Abstract
The invention provides a double-row cylindrical roller retainer with hold depths on a single side. The whole retainer is ring-shaped, and a plurality of pocket holes with opposite opening directions are uniformly formed in two sides of the retainer, and are distributed in a staggered manner. The double-row cylindrical roller retainer with the lock amounts on the single side is characterized in that the hold depths are arranged on the pocket holes in one side of the retainer. The retainer can be used for a double-row cylindrical roller bearing with a flange on an outer ring, a mounting notch is not required to be formed in the outer ring, and an inner ring does not have a flange. When the inner ring is separated from an outer assembly, rollers cannot be scattered; the circumstance that rolling bodies cannot be pushed into the retainer or drop voluntarily after being pushed into the retainer in an assembling process of the bearing is avoided; the retainer is assembled and disassembled repeatedly to maintain the enough hold depths; and the rollers cannot be scattered.
Description
Technical field
The present invention relates to the double-row cylindrical roller retainer of one-sided band hold depth, be applied to the collateral support roller bearing of milling train, belong to field of metallurgy.
Background technique
In heavy industry field, no matter be cold rolling or the actual conditions of hot rolling is all very severe, in order to ensure the service precision of equipment, so need regularly to carry out maintaining and maintenance to the component of equipment.This retainer bearing used also must regular dismounting cleaning maintenance, there will be the technical barrier such as mechanical deterioration and trap difficulty when dismounting bearing simultaneously.
Summary of the invention
Reduce when dismounting bearing the mechanical deterioration of bearing for reducing user and reduce trap difficulty, the invention provides the double-row cylindrical roller retainer of one-sided band hold depth, adopt the installation process of self-compiling program simulation retainer, impact is installed to the given rational design parameter in lock point place, pocket hole of rolling element, avoid bearing occur in assembly process rolling element by do not enter retainer or by after rolling element situation about dropping voluntarily occur.
To achieve these goals, the technical solution adopted in the present invention is: the double-row cylindrical roller retainer of one-sided band hold depth, retainer entirety is in ring, retainer both sides are evenly provided with some pocket holes that opening direction is contrary, described two side pocket holes are interspersed, and it is characterized in that being provided with hold depth on retainer one side pocket hole.
The design parameter of described hold depth is determined according to the overall precision of bearing and rolling element size; Hold depth scope is 5-30 silk, 1=0.01mm.
Fore shaft place with retainer pocket hole, hold depth side designs for circular arc type, when inner ring and outer components apart, roller is not scattered, even if after being dismounted for multiple times, retainer still can have enough hold depths to pin roller, making it not to be scattered, also reducing the resistance when assembling roller simultaneously.
The invention has the beneficial effects as follows: this retainer can be applicable to the Biserial cylindrical roller bearing of outer ring being provided with raised edge, outer ring does not need design and installation breach, and inner ring is not with rib.When inner ring and outer components apart, roller is not scattered; Avoid bearing occur in assembly process rolling element by do not enter retainer or by after rolling element situation about dropping voluntarily; Being dismounted for multiple times retainer keeps enough hold depths, and roller is not scattered.

Fig. 2 is retainer axial subdivision schematic diagram.
Fig. 3 is retainer locking measurement pocket hole elevational schematic.
Fig. 4 is the close-up schematic view of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Fig. 1 to Fig. 4, the double-row cylindrical roller retainer of one-sided band hold depth, retainer entirety is in ring, retainer both sides are evenly provided with some pocket holes that opening direction is contrary, described two side pocket holes are interspersed, it is characterized in that being provided with hold depth on retainer one side pocket hole, the snap close place, pocket hole of locking measurement is simultaneously arc-shaped structure.Hold depth be come according to the overall precision of bearing and rolling element size fixed.When the precision of bearing is high, when the size of rolling element is less, designed hold depth can be suitable less, and hold depth scope also can be slightly narrow, otherwise then get large hold depth, and the scope of hold depth also should be relaxed.Usual hold depth is chosen according to bearing integral calculation of design parameters in 5-30 silk (1=0.01mm) scope, and choosing of hold depth also will in conjunction with the restriction of actual working ability and process engineering, this design parameter is based on theory calculate, in conjunction with what determine after empirical value correction.
Claims (3)
1. the double-row cylindrical roller retainer of one-sided band hold depth, retainer entirety is in ring, retainer both sides are evenly provided with some pocket holes that opening direction is contrary, described two side pocket holes are interspersed, it is characterized in that being provided with hold depth on retainer one side pocket hole, the snap close place, pocket hole being simultaneously with hold depth side is arc-shaped structure.
2. the double-row cylindrical roller retainer of one-sided band hold depth according to claim 1 is characterized in that: the design parameter of described hold depth is determined according to the overall precision of bearing and rolling element size; Hold depth scope is 5-30 silk, 1=0.01mm.
