Because the bearing capacity of the Automobile Tire Co., during the lifting operation must put down the leg, make tire overhead, and the car must be the away leg. There are two legs before and after the crane bearing , each leg were controlled by the manual reversing valve, the legs with horizontal and vertical hydraulic cylinder hydraulic cylinder (mobile crane bearing ).Vertical hydraulic cylinder with bidirectional hydraulic lock, to ensure that the leg is reliably locked, prevent the lifting operations occurring in the process of Soft Legs phenomenon or in the driving process of hydraulic legs automatically falls,ferris wheel bearing .

How to choose the axial bearing

In order to obtain the high accuracy, high rigidity of the feed system, should not only choose the ball screw with high precision and high rigidity to the side, and must attach great importance to the design of ball screw support.

In order to obtain the high accuracy, high rigidity of the feed system, should not only choose the ball screw with high precision and high rigidity to the side, and must attach great importance to the design of ball screw support. Because the main load of the ball screw's axial load, radial load weight, from the horizontal screw therefore, required axial precision ball screw and stiffness is very high. Due to the feed system of CNC engraving and milling machine request flexible movement, the small displacement of the (small angle screw) response to sensitive, so should choose high running precision, miniature linear bearings stiffness and high, little friction torque of rolling bearing. At present, various types of bearings is the most used 60b contact angle of angular contact thrust ball bearing.CNC engraving and milling machineBed choose this angular contact ball bearings, usually need to combine 2 or more bearings, and the preload to use. The combination of the form of back-to-back group (DB mode), face to face group (DF mode), the series group (DT mode). This kind of bearing used in CNC engraving and milling machine when, in order to easy to absorb different axis between a ball nut and a bearing, the general use of DF group mode. View Details

Thrust into the thrust bearing and thrust ball bearing roller bearings.Thrust ball bearings are divided into thrust ball double row ball slewing bearing and angular contact ball bearings with raceways from the washer and ball and cage components and the shaft with raceway ring called shaft washer, and the shell with the raceway ring called seat bidirectional bearing will be in the ring and the shaft with one-way bearings can withstand axial load, two-way bearings can withstand axial load. appear before the installation of seat spherical bearings with aligning properties, can reduce installation impact of errors. these bearings are mainly used in automobile steering mechanism, the machine spindle.Thrust into thrust cylindrical roller bearing roller bearings, spherical roller thrust bearings, thrust tapered roller bearings, thrust needle roller metallurgical bearing.Thrust cylindrical roller bearings are mainly used in oil drilling rig, the system iron steel machinery.Spherical Roller Bearings Thrust bearings are mainly used in such hydroelectric power, vertical motors, marine propeller shafts, crane, extrusion machines.Thrust Tapered Roller Bearings These bearings main purposes: one-way: crane hooks, swivels bi oil rig: rolling mill roll neck.Thrust bearing assembly major axial load, its wide range of applications. Although the thrust bearing installation operation is relatively simple, but the actual service is still often an error occurs, the tight and loose ring ring bearing installation location that is incorrect, the results of the ship loader bearing out of action, the journal soon be worn. Clamping ring mounted on the end face of the stationary member, i.e., the error assembling. Tight inner ring and the journal for transition fit to drive when the shaft rotates tight ring, and the end surface friction with the stationary element, axial forces in the subject (Fx), it will appear larger than the inner diameter of the friction torque with the drag torque, resulting in tight ring and the shaft with face mandatory rotation, increased wear journal.

Induction heater, is widely used in metallurgy, coal, petroleum, railway, construction machinery, mining, paper, textiles, building materials and other industries.Induction heater is suitable for heating the assembly process requires interference fit construction machinery bearing, gears, bushings, diameter ring, pulleys, contractile ring, connectors and other specifications of the annular cylindrical metal workpiece, the workpiece to achieve the best too surplus assembly needs.Traditional installation ----- percussion, press pressure, flame heating, cooking oil, etc. There are a lot of drawbacks. Compared with traditional methods of induction heating method shows great advantages, the installation program is worthy choice.Traditional methods and induction heating method was moreTraditional methods:1, percussion: big labor intensity and easy to damage to the workpiece.2, press pressure: reduce the accuracy of the mating surfaces and affect the results.3, flame heating: temperature easy to control, easy to damage the workpiece.4, the oil and cook: a serious loss, reduce the accuracy of the workpiece, pollute the environment.Induction heating method:1, high: in a very short period of time to heat the workpiece, and low labor intensity.2, environmental protection: pollution.3, energy: just use of power, and high thermal efficiency.4. Quality: no damage to the workpiece and the mating surface, and to achieve the best installation results. View Details

Thrust bearings are generally made up of two or more thrust washers thrust washer and several rolling body composition, general thrust washer into the shaft piece and seat sheet, generally the most common type of rolling by iron or copper mass holder integrally combined. The most common type is the ball bearing type thrust bearings. Thrust bearings are used exclusively dedicated bearing axial force is the force in the direction parallel to the axis of the axial bearing.Thrust bearings are also known as thrust bearings.Thrust ball bearing is a separate type of bearings, shaft ring, seat ring and the cage can be, the ball component separation. Shaft ring is cooperating with the shaft collar, seat is compatible with the bearing hole of the ring, and there is a gap between the shaft; thrust ball bearings can only bear axial load, one-way thrust ball bearings can withstand axial load in one direction, two-way thrust ball bearings can withstand axial load in both directions; thrust ball bearings can not limit the radial displacement of the shaft, low speed limits, one-way thrust ball bearings can limit a shaft and housing axial displacement direction, two-way bearing can limit the axial displacement in both directions.Thrust roller slewing ring bearing for axial load mainly axial, radial joint load, but the radial load shall not exceed 55% of the axial load. With the other thrust roller bearings, such bearings lower friction coefficient, high speed, and with self-aligning performance. 29000-type non-stick bearing symmetrical spherical roller, can reduce the roller and raceway relative sliding at work, and roller long, large diameter roller quantity, high load capacity, usually in oil lubrication, individual low speeds available grease. In the design selection, preference should be given; 80000 Thrust cylindrical roller bearings, 90000 Thrust tapered roller bearings and thrust needle roller bearings AXK type, can withstand a one-way axial load, than the axial thrust ball bearings much greater load capacity and rigidity, occupying a smallaxial space. Thrust cylindrical roller bearings and thrust needle roller bearings for low speed applications, thrust tapered roller bearings speed slightly higher than the thrust cylindrical roller bearings.

Since the new assembly parts with the gap is small and due to assembly and other reasons, it is difficult to ensure uniformity with the gap axial bearing, the lubricant (grease) of the friction surface is not easy to form a uniform film, to prevent wear. Angular contact ball bearings Thereby reducing the effectiveness of lubrication, causing the early parts of abnormal wear. Will cause serious friction with precision surface scratches or bite, leading to failure. 3. Loosening The new processing and assembly of components, there is a deviation of the geometry and with the size of the initial period, due to shock, vibration, etc. turntable bearings alternating load, and the effects of heat, deformation and other factors, coupled with excessive wear and tear and other reasons, easy to make the original fastening parts loosening.
