Abstract
The invention discloses a bearing design method and a bearing structure for preventing slippage, relating to the technical field of bearings. According to the method, the outer surface of a bearing outer ring (1) is set to be of a square structure, the mounting surface of a bearing base matched with the outer surface of the bearing outer ring (1) is set to be of a square structure, the inner surface of a bearing inner ring (2) is set to be of a square structure, and a shaft mounting surface matched with the inner surface of the bearing inner ring (2) is set to be of a square structure. By adopting the bearing design method and the bearing structure, the problems of slippage, creepage and the like between the bearing inner ring 2 as well as the bearing outer ring 1 and a matching surface under a heavy load are solved; the bearing inner ring 2 and the bearing outer ring 1 are in clearance fit with the bearing matching surface, so that the problem of breakage of a bearing ring in a big-interference state is solved effectively, and relevant rotating and positioning accuracies are not influenced. Meanwhile, the problem of difficulty in assembling and disassembling of the bearing is solved effectively, and the production cost is low.
Description
[technical field]
The present invention relates to technical field of bearings, specifically the present invention relates to a kind of design bearing method and structure thereof of anti-slip.
[background technique]
Known, cooperation between Machine Design middle (center) bearing and axle and bearing support generally coordinates and adopts interference fit according to movement parts, static element coordinates the principle that adopts Spielpassung, to guarantee that effective combination of movement parts and bearing fit face guarantees the normal delivery of motion, but large in some temperature variation, load is large, load fluctuation is large and structure connects the high occasion of reliability requirement, Internal and external cycle often all needs to adopt interference fit simultaneously.
For internal-and external diameter, adopt the bearing of interference fit simultaneously, traditional bearing structure Internal and external cycle fitting surface is cylndrical surface, the advantage of this structure is that Internal and external cycle is that cylinder revolution processing is more convenient, but in the situation that internal-and external diameter is interference fit, it is very thorny that bearing installation question just becomes, the general method adopting is first bearing enclose separation to be passed through respectively to heating or freezing method now, inner and outer ring is respectively installed to axle and bearing support specified position, then by retainer and rolling element being locked into an assembly with the retainer of lock ball or lock roller, be installed on bearing inner race or bearing outer ring, and then be mounted to one with bearing outer ring or inner ring together with axle or bearing support, such assembly method, easily there is following problem, first said method requires bearing enclose be able to separate, this is for radial ball bearing, the indissociable bearing such as spheric roller bearing just cannot adopt the method, secondly said method requires retainer can lock rolling element, has increased the structural design of retainer and the difficulty of processing, and lock is too tight simultaneously, affects bearing operation performance, and the too pine of lock, easily drops in rolling element installation process, in addition due to Internal and external cycle respectively interference be arranged in axle and bearing support, the dimensional accuracy of bearing location and installation position necessarily requires the very tight of control, otherwise after easily occurring that bearing is installed, the too large and too little situation in bearing internal void, affect the usability of bearing, be a technical barrier so internal-and external diameter is the installation question that how to solve bearing in the situation of interference fit always.
[summary of the invention]
In order to overcome the deficiency in background technique, the invention discloses a kind of design bearing method and structure thereof of anti-slip, outer surface and bearing inner race 2 internal surfaces by bearing outer ring 1 are set to square structure, the mounting surface of the bearing support matching with the outer surface of bearing outer ring 1 is set to square structure, be set to square structure with the match mounting surface of sympodium of bearing inner race 2 internal surfaces, the present invention efficiently solves in temperature variation large, load is large, load fluctuation is large, structure connects the high occasion of reliability requirement, the problem that bearing enclose lasso skids and the installation question of bearing.
For achieving the above object, the present invention adopts following technological scheme:
A kind of design bearing method of anti-slip, comprise the bearing body that bearing outer ring, bearing inner race, retainer and rolling element form, described method is that the outer surface of bearing outer ring is set to square structure, the mounting surface of the bearing support matching with bearing outer ring outer surface is set to square structure, the internal surface of bearing inner race is set to square structure, and the axle mounting surface matching with bearing inner race internal surface is set to square structure.
The design bearing method of described anti-slip, the outer surface of described bearing outer ring and the mounting surface of bearing support are Spielpassung.
The design bearing method of described anti-slip, described bearing inner race internal surface and axle mounting surface are Spielpassung.
The design bearing method of described anti-slip, the equal 0-30um of described Spielpassung.
A kind of bearing structure of anti-slip, comprise bearing outer ring, bearing inner race, retainer and rolling element, the outer surface of described bearing outer ring is square structure, inside at bearing outer ring is provided with bearing inner race, the internal surface of described bearing inner race is square structure, described rolling element is arranged in the raceway between bearing outer ring internal surface and bearing inner race outer surface, and described retainer is evenly separated a plurality of rolling elements.
Owing to having adopted technique scheme, the present invention has following superiority:
The design bearing method of anti-slip of the present invention and structure thereof are set to square structure by outer surface and bearing inner race 2 internal surfaces of bearing outer ring 1, the mounting surface of the bearing support matching with the outer surface of bearing outer ring 1 is set to square structure, and the axle mounting surface matching with bearing inner race 2 internal surfaces is set to square structure; The present invention has fundamentally avoided occurring between heavily loaded lower bearing inner ring 2 and bearing outer ring 1 and fitting surface skids and the problem such as creep; Between bearing inner race 2 and bearing outer ring 1 and bearing fit face, adopt Spielpassung, effectively avoided the problem that bearing ring breaks when large interference state, and do not affect relevant rotation positioning precision, effectively solved again bearing and installed and removed difficult problem simultaneously, when bearing is installed, do not need can install bearing inner race 2 is separated with bearing outer ring 1, cost of production is lower.
