Abstract
The utility model provides a plurality of pocket holes that biserial cylindrical roller holder of unilateral area hold depth, the whole ring that is of holder appears, evenly is equipped with opening opposite direction on the holder both sides both sides pocket hole is crisscross the distribution, and its characterized in that is equipped with the hold depth on a holder side pocket hole. The biserial cylindrical roller bearing of outer astragal flange can be applied to to this holder, and the outer lane does not need the design and installation breach, and the flange is not taken to the inner circle. The roller does not fall scattered when the inner circle separates with outer subassembly, avoid the bearing rolling element to appear according to the condition of not advancing the holder or dropping by oneself according to last back rolling element in assembling process, the dismouting holder keeps enough hold depths many times, and the roller does not fall scattered.
Description
Technical field
This utility model relates to the double-row cylindrical roller retainer of unilateral band hold depth, is applied to milling train collateral support roller bearing, belongs to field of metallurgy.
Background technology
In heavy industry field, no matter it is cold rolling or the actual condition of hot rolling is all very severe, in order to ensure the service precision of equipment, so needing periodically the parts of equipment to be carried out maintaining and maintenance.Bearing used by this retainer also must regular dismounting cleaning maintenance, there will be the technical barrier such as mechanical damage and trap difficulty when dismounting bearing simultaneously.
Summary of the invention
Reduce the mechanical damage to bearing when dismounting bearing for reducing user and reduce trap difficulty, this utility model provides the double-row cylindrical roller retainer of unilateral band hold depth, use the installation process of self-compiling program simulation retainer, impact is installed the given rational design parameter in lock point place, pocket hole of rolling element, it is to avoid bearing occur during assembling rolling element by do not enter retainer or by after the situation appearance dropped voluntarily of rolling element.
To achieve these goals, this utility model be the technical scheme is that the double-row cylindrical roller retainer of a kind of unilateral band hold depth, retainer is overall in annular, the plurality of pockets that opening direction is contrary it is uniformly provided with on retainer both sides, described two side pocket holes are interspersed, it is characterised in that be provided with hold depth on retainer one side pocket hole.
The design parameter of described hold depth determines according to overall precision and the rolling element size of bearing；Hold depth scope is 5-30 silk, 1=0.01mm.
Design for circular arc type at fore shaft with retainer pocket hole, hold depth side, when inner ring and outer components apart, roller is not scattered, even if after being dismounted for multiple times, retainer remains able to enough hold depths and pins roller, it is allowed to not be scattered, also reduces the resistance when assembling roller simultaneously.
The beneficial effects of the utility model are: this retainer can be applicable to the Biserial cylindrical roller bearing of outer ring being provided with raised edge, and outer ring need not design and installation breach, and inner ring is without rib.When inner ring and outer components apart, roller is not scattered；Avoid bearing occur during assembling 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. 4 is the close-up schematic view of Fig. 3.
In figure: I, arc-shaped structure, 1, retainer, 2, fore shaft, 3, pocket hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
Fig. 1 to Fig. 4, a kind of double-row cylindrical roller retainer of unilateral band hold depth, retainer is overall in annular, the plurality of pockets that opening direction is contrary it is uniformly provided with on retainer both sides, described two side pocket holes are interspersed, it is characterized in that being provided with hold depth on retainer one side pocket hole, be arc-shaped structure at the pocket hole fore shaft of band hold depth side simultaneously.Hold depth is the overall precision according to bearing and rolling element size come the most fixed.When the precision of bearing is high, and when the size of rolling element is less, designed hold depth can be suitable less, and hold depth scope also can be the narrowest, otherwise then takes big hold depth, and the scope of hold depth also should be relaxed.Generally hold depth calculates according to bearing overall design parameters in the range of 5-30 silk (1=0.01mm) and chooses, and choosing of hold depth also will be in conjunction with actual working ability and the restriction of Technology, this design parameter is based on Theoretical Calculation, determines after incorporating experience into value correction.
