Crossed Roller Bearings abnormal sound occurred during the operation, a wide range of formation mechanism is more complex, factors that are multifaceted, and various abnormal sound often added together, it is difficult to distinguish, mainly due to the following categories:1. The bearing inner and outer raceway presence bump hurt, scratched or periodic vibration pulse serious defect.2. Scroll surface bump hurt of rolling bearing, aperiodic oscillation pulse scratches and other defects caused.Periodic or aperiodic oscillation pulse3. Since residual magnetism adsorption iron powder present on the raceways or rolling elements caused.4. impurities or dust into the bearing raceway pulse caused by aperiodic vibration. Must be done in space when high cleanliness of cross roller bearing assembly.5. aperiodic oscillation pulse violent collision between the rolling element and spacer blocks caused.6. poor performance lubricants, rolling vibration pulse generated when the lubricant sliding friction between the rolling element and spacer blocks and the rolling elements running. Crossed roller Slewing Bearing senior grease, in order to ensure the use of sophisticated demand environment.

Thrust ball bearings are divided into one-way thrust ball bearings and double direction thrust ball bearing, thrust ball bearings with aligning seat two-way thrust ball bearings, one-way thrust ball bearings with aligning seat thrust ball bearing ring. Thrust ball bearings include a shaft washer, two races and two ball - cage assembly. The bearings are separated type, all the parts can be installed independently. Two-way and one-way bearing is bearing the same shaft ring, seat ring and ball - cage assembly, in order to get a good running bearings, thrust ball bearings, like all ball bearings and roller bearings, must bear a certain minimum load , especially in the high speed or high acceleration, or if rapid changes in the load direction. Friction in these conditions, the inertia forces of the balls and cage and rolling bearing lubricant will have a negative impact, may produce damaging bearings sliding motion between the ball and the raceways. The case started at low temperatures or very high viscosity of the lubricant, may require larger minimum load. Weight bearing support, coupled with external forces, especially in the vertical axis of the condition, usually more than the minimum load required, it must be subjected to preload, such as a spring.

Show cross spiral line traces the emergence of such traces is mainly due to the bus straight wheel of existence, bump phenomenon, when in grinding, the grinding wheel and the workpiece is only part of the contact, when the workpiece or the grinding wheel reciprocating motion after several times, linear plain bearings cross spiral line and the naked eye reproduced on the workpiece performance will be observed. The helix pitch and workpiece speed, rotational speed of workpiece size, but also with the wheel axis and the guide rail is not parallel to the working table.(a) the main reason for the formation of the spiral line1 grinding wheel dressing is bad, not chamfered corner, without the use of cooling liquid dressing;Track 2 table guide lubrication oil too much, cause the work station floating;3 machine tool accuracy is not good;4 the grinding pressure and so.(two) with the formation of the spiral line1.V guide not good rigidity, the grinding wheel edge offset, mobile crane bearing just contact with the work surface;2 dressing noisy round table reversing speed is not stable, the precision is not high, the grinding wheel is a slightly less edge trimming;The 3 workpiece itself poor rigidity;4 wheel is broken too peeled off the sand and grinding of iron deposition in the grinding wheel on the surface, this should be trimmed grinding wheel with cooling water rinse or wash clean;5 wheel dressing is not good, local projection etc..Analysis of causes of bearing grinding traces generated View Details

How to improve the matching precision cross ball and roller combined bearing installation.In order to improve the matching precision crossed roller bearing installation, must use the measurement methods and tools do not make the ball and roller combined bearing, precision measurement of bearing inner and outer circle with the surface size of the actual project, the measurement can be related to the inner and outer diameters of all be measured, and make a comprehensive analysis of the measured data according to this, precision, matching with the shaft and hole of shaftThe installation part size. The distribution of shaft and hole in the actual measurement of the corresponding size and geometry, temperature and measurement should be carried out in the bearing under the same. To guarantee the higher actual tie effect, the shaft and hole matched with a bearing surface, the roughness should be as small as possible.In the above measurement, should be in the outer circle and cross self-aligning roller bearing inner hole, and the corresponding surface of the shaft and the seat hole, on both sides near the assembly chamfer, respectively two groups of marker can indicate the maximum deviation direction, so that in the actual assembly, so that the large deviation match two party aimed at the same azimuth, in this assembly, both of deviation to partially offset.

The quality of judgment ball and roller combined bearing

Bearing surfaces should be bright is kind of glossy black, glossy black is the cause of this steel bearings are used in compliance with its grinding and cutting fluid used, such as generated, which dominated the previous two. 2, chamfer is bright Bearing chamfer does not determine the quality of the bearing, but it reflects the processing method of NSK bearings. Chamfer is black, after hardening heat treatment, thus increasing the hardness of the bearing, and some people think that black does not look good chamfering processing is not perfect, this is a misunderstanding.

Discussion on thin-walled deep groove ball bearing in the concrete development trend in the future
2015-01-15
The development level of thin-walled deep groove ball bearing, deep groove ball bearing common thin-wall can completely replace the imported ball and roller combined bearing, but the function of thin-walled deep groove ball bearings with high technical content is still to be developed, will be the future of thin-walled deep groove ball bearing indu... The development level of thin-walled deep groove ball bearing, deep groove ball bearing common thin-wall can completely replace the imported ball and roller combined bearing, but the function of thin-walled deep groove ball bearings with high technical content is still to be developed, will be the future of thin-walled deep groove ball bearing industry has a new transformation and upgrading:With the development of society, the domestic and foreign customers put forward higher requirements on the product, customers put forward style and requirement is very likely not matching with the roller bearing member. In order to meet customer requirements, development needs the co-operation of thin-walled deep groove ball bearing the company's involvement in the new product. The manufacturer and the thin-walled deep groove ball bearings manufacturers cooperation, make full use of both the design, technology, equipment advantage, the formation of a new format, thin-walled deep groove ball bearing parts and new synchronous design, synchronous manufacturing, common debugging, make the best allocation of social resources.Thin-walled deep groove ball bearing into roller bearing parts and decorative function of roller bearing two categories. A lot of thin-walled deep groove ball bearing parts maker invisible to the two separated, decorative thin-walled deep groove ball bearing parts do not pay attention to functional development, function of double direction thrust ball bearing the decorative development research, between the dislocation. With the trip to Sacramento roller bearing as an example, for many years, the structure function of improving continuously improve, but do not pay attention to the unity of the many decorative products, although very good, but always looks not pleasing to the eye. With increasing the level of innovative design in recent years, there are many designers in the attention of thin-walled deep groove ball bearings, to the industrial design philosophy to examine the roller bearing, the appearance and function better thin-walled deep groove ball bearing fusion is the development trend of the thin-walled deep groove ball bearing.
