Abstract
The utility model provides a novel subdivision formula bearing cylindrical roller bearing retainer, is including dividing into two semicircular outer lanes, two semicircular inner circles of share, a set of cylindrical roller, dividing into two semicircular holders, dividing into two semicircular location snap rings and the fixed spring card of using of holder. Two semicircular holders are the semi -circular holder that has roller pocket hole and both ends and have the connecting hole, first one of the pocket hole in roller pocket hole adopts square straight hole, the convex straight hole of pocket hole lower half adoption, two semi -circular holders adopt all disposable injection molding of aluminum alloy, when two semi -circular holders assemble, through both ends spring card holder that links into an integrated entity for the connecting hole. The utility model discloses a cylindrical pocket hole increase oil storage space is protected than the conventionality in particular form's roller pocket hole, is favorable to the formation of lubricating oil film, has reduced the stress concentration that the holder produced when guiding to the roller, has improved the behavior in service and the life of bearing.
Description
Technical field
The utility model relates to bearing mnanufacture technical field, particularly relates to a kind of Novel subdivision formula bearing roller retainer.
Background technique
Split type bearing with cylinder roller develops on the basis of integrated type roller bearing.Its structure by being divided into two semicircular outer rings, be divided into two semicircular inner rings, be divided into two semicircular retainer assemblies with cylindrical roller and two semicircular location snap rings form.
Traditional Split type bearing with cylinder roller retainer links together by being divided into two semicircular maintenance stands and retainer lid employing rivet and screw, a kind of mode started as bearing by roller guide retainer., there is certain drawback in the joint cage of this employing more than one piece Combined machining assembling.By mechanical processing process such as car, milling, brill, wire cutting machine tools, roller and retainer pocket hole, maintenance stand and the often bad connection of retainer lid, simultaneously because adopting rivet and screw fixed retainer, easily misplace after keeping stand and the assembling of retainer lid, rivet and screw in use easily produce loose or dislocation.
Model utility content
The technical problems to be solved in the utility model is, there is provided one can improve retainer join strength and stability, realize the accurate guiding of retainer, roller contacts well with pocket hole, reduce the shifting amount of roller in pocket hole, simplify the Novel subdivision formula bearing roller retainer of bearing assemble process.
The technological scheme adopted is:
A kind of Novel subdivision formula bearing roller retainer, comprises and is divided into two semicircular outer rings, is divided into two semicircular inner rings, one group of cylindrical roller between inner ring and outer ring, separation guide being divided into two semicircular retainers, being divided into two semicircular location snap rings and retainer fixing spring card of cylindrical roller.Described be divided into two semicircular retainers and be with roller pocket hole and the two ends semicircle retainer with attachment hole, described two semicircle retainers with roller pocket hole and two ends attachment hole adopt all disposable die cast of aluminum alloy, when two semicircle retainers assemblings, to be linked into an integrated entity retainer by two ends attachment hole spring clip.
The pocket hole first half in the roller pocket hole of above-mentioned retainer adopts square straight hole, and pocket hole Lower Half adopts circular arc straight hole, and the square straight hole of the pocket hole first half and Lower Half circular arc straight hole all adopt the disposable die cast of aluminum alloy.
After above-mentioned cylindrical roller and retainer roller pocket hole are assembled, retainer roller pocket hole axis and retainer external diameter intersection, adopt mold integral to roll the locking pressure point pinning roller.
The utility model semicircle Integral retainer pocket hole first half adopts square straight hole, pocket hole more cylindrical than conventional retainer, increase oil storage space, be conducive to the formation of lubricant film, roller is contacted well with retainer, improves the greasy property of bearing, improve the guiding of retainer to cylindrical roller, special pocket hole shape decreases retainer concentrating the stress produced during roller guide, improves runnability and the working life of bearing.
The semicircle Integral retainer of the utility model adopts aluminum alloy one-step die casting, improves retainer bulk strength, substitutes brass and saves material.
