Abstract
The invention provides a nonstandard ultralight precise angular contact ball bearing of an RV speed reducer. The precise angular contact bearing provided by the invention comprises an outer ring, an inner ring, a rolling body and a retainer, wherein the rolling body is arranged on the retainer to form an assembly; the outer ring is arranged at the periphery of the assembly of the rolling body and the retainer; and the inner ring is arranged in the assembly of the rolling body and the retainer. The precise angular contact ball bearing provided by the invention is mainly applied to the precision transmission industries with small space and high speed ratio, such as robots, welding positioning tables (roll-over tables), numerical control machines, precision radar driving control. The precise angular contact ball bearing provided by the invention has the advantages of complex structure, high precision, high technology additional value and obvious economic benefit.
Description
(1) technical field
The present invention relates to the precision drive industry, be specifically related to a kind of accurate angular contact ball bearing.
(2) background technique
RV speed reducer---precision bearing speed reducer, accurate cycloid speed reducer are the speed reducers that robot uses.As its name suggests, the key point of its speed reducer is the precision positioning of bearing.It is big to require bearing to have output torque, highi degree of accuracy, load is big, volume is little, in light weight, high rigidity, low noise, long lifetime, running steadily, safety reliability is big, can adapt to premium properties such as carrying under the HI high impact continuous operation for a long time in rugged environment.
Because the limited space and the precision height of robot, the existing standard bearing can't meet the demands, so the accurate angular contact ball bearing of the series of the bearing criteria of right and wrong ultralight on the RV speed reducer.At present domestic still do not have a RV speed reducer upper bearing (metal) that any manufacturer production robot uses, the RV speed reducer of domestic production supporting bearing all by import.
(3) summary of the invention
The object of the present invention is to provide that a kind of volume is little, in light weight, the accurate angular contact ball bearing of the non-standard ultralight series of RV speed reducer of high loading, high rigidity, highi degree of accuracy, high safety reliability.
The object of the present invention is achieved like this: it comprises outer ring 1, inner ring 2, rolling element 3, retainer 4, rolling element 3 is arranged on the retainer 4 forms assemblying body, outer ring 1 is arranged on the assemblying body periphery of rolling element 3 and retainer 4, and inner ring 2 is arranged in rolling element 3 and retainer 4 assemblying bodys.
The present invention also has some technical characteristicss like this:
1, described retainer 4 is provided with breach;
2, described outer ring 1 is provided with inclined flange;
3, described inner ring 2 is provided with not contour rib.
For satisfying the requirement of bearing usability, design proposal of the present invention is as follows:
1. adopt optimizing design scheme, reasonably adjusted main parameter, when improving the bearing load rating to greatest extent, also will guarantee the requirement of the high rigidity of bearing.Therefore, we determine that at the little characteristics of sectional area of ultralight series bearing the rolling element diameter increases than unidimensional rolling element diameter, and the quantity of rolling element has increased a plurality of.
2. for making bearing can bear axial and united load, determine that according to the shaft strength analysis wrapping angle of bearing of the present invention is 50 °.
3. retainer has been chosen new engineering material nylon PA66, but molding and forming, therefore, can process the complicated shape that helps bearing working, under the certain situation in space, can hold the rolling element more down, that diameter is bigger, meet design requirement to greatest extent, lubrication state is improved simultaneously.
4. the shaped design of retainer has changed traditional ring-like design.On normal annular, cut a fritter, promptly on annulus, form a small gap, the requirement that helps the bearing assembling and expand with heat and contract with cold.
5. outer ring inclined flange, inner ring is the design of contour rib not, helps bearing lubrication and heat radiation.
6. adopt press hardening technology: because very easily distortion in the ultralight series product heat treatment process is controlled deformation, adopt press hardening, reduced reject rate, thereby reduced the cost of bearing.
The present invention is mainly used in robot, welding displacement platform (roll-over table), numerical control machine tool, precision radar drive controlling etc. and requires the precision drive industry that the space is little, speed ratio is big." the accurate angular contact ball bearing of the non-standard ultralight series of RV speed reducer " complex structure, precision height, technical value added height, remarkable in economical benefits.
The present invention has adopted optimizing design scheme, and it is big to have satisfied RV speed reducer output torque, and volume is little, in light weight, the requirement of high loading, high rigidity, highi degree of accuracy, safety and reliability; Retainer has adopted nylon PA66 material, makes its impact resistance significantly improve when bearing 5 times of nominal torques (even, product can not damage yet), running steadily, noise is low, self-lubricating property good, bearing life is improved; Owing to determined the rational wrapping angle of bearing, made bearing can bear axial and united load.Therefore, can guarantee that the RV speed reducer is in the medium-term and long-term continuous operation of the rugged environment of bearing the HI high impact carrying.
Along with industrial expansion, the increase year by year of robot consumption, the trend that the output of RV speed reducer linearly rises over past ten years.Year is produced 6000 robots approximately, needs 18000 RV speed reducers.External each advanced industrial country is all being developed the research of robot, especially with Japan for.Demand to the RV speed reducer is very big, and the RV speed reducer of international most advanced level all has wide market both at home and abroad, and prospect is quite optimistic.Therefore the exploitation of estimating these series product occupancy in market at home can reach more than 90%, and the occupancy of international market can reach about 30%.The technology of the present invention content height, remarkable in economical benefits, has vast market prospect.
