Abstract
The application discloses special rolling bearing unit suitable for heavy track dolly, including bearing and bearing frame, the bearing frame has the outer lane, has a dead eye in the middle part of the outer lane, install the bearing in the dead eye, the outer tip of bearing frame is provided with a retaining ring, is equipped with the screw hole on the retaining ring, the screw hole cooperation is connected with ejecting screw, the lower extreme of bearing frame is provided with two mounting holes. Rolling bearing unit is convenient to be dismantled, and reasonable size design makes the special bearing bearing capacity bigger, and the cost is lower.
Description
Technical field
The application relates to a kind of rolling bearing units, particularly a kind of special rolling bearing units being applicable to heavy track dolly.
Background technique
Small rail car is widely used in enterprise, and it is applicable to short-range article transmission, produce in chain and play important effect, and heavy track dolly is generally applied in the industry-by-industries such as mining industry, smelting, steel in enterprise.At present, because heavy track dolly working environment gravity is large, the large various factors that waits of dust easily causes its bearing damage used, thus heavy dolly cannot normally be used, and causes the loss of enterprise.Common standard rolling bearing units, it uses material to be cast iron, and bearing seat wall thickness is too thin, meet the easy fragmentation of impact force rear bearing pedestal damaging internal bearing then in actual use, and when assembling, Bearing support external force is knocked and is had certain destruction into the bearing capacity of bearing support to rolling bearing units.
Model utility content
The object of the application is: for the defect of prior art, a kind of special rolling bearing units being applicable to heavy track dolly are provided, these rolling bearing units not only structure are simple, rationally distributed, and effectively can overcome the deficiency of common standard rolling bearing units, ensure bearing capacity and the dust-proof effect of bearing, installation for convenience detach.
The technological scheme that the application adopts is: a kind of special rolling bearing units being applicable to heavy track dolly, and comprise bearing and bearing support, described bearing support has outer ring, has a bearing hole, be provided with bearing in described bearing hole in the middle part of outer ring; Bearing support outer end is provided with a back-up ring, and back-up ring is provided with tapped hole, and described tapped hole is connected with and ejects screw; The lower end of bearing support is provided with two mounting holes.
Described tapped hole is 6, is uniformly distributed along the circumference on back-up ring.
Described bearing support outer ring thickness t the best is 8mm.
The material of described bearing support is preferably A3 steel.
After adopting technique scheme, the beneficial effect of the application is: the design of bearing hole makes the shaft strength of installation even, and can not damage bearing and bearing support; Only need rotate during dismounting bearing and eject screw detachably, on bearing support, rational bearing hole and outer ring thickness add the bearing capacity of bearing, and cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the application;
Fig. 2 is the structural representation of the application's bearing support;
Fig. 3 is the sectional view at A place in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing to the application's further instruction:
In figure: 1. bearing support; 2. bearing; 3. eject screw; 101. bearing hole; 102. back-up ring; 103. tapped hole; 104. mounting hole; 105. outer ring.
Be applicable to special rolling bearing units for heavy track dolly, comprise bearing 2 and bearing support 1, bearing support 1 has outer ring 105, and outer ring thickness is 8mm; There is a bearing hole 101 in the middle part of outer ring, in bearing hole, bearing is installed; Bearing support 1 outer end is provided with a back-up ring 102, and back-up ring is provided with tapped hole 103, and tapped hole is connected with and ejects screw 3; The lower end of bearing support is provided with two mounting holes 104.
The tapped hole 103 of above-mentioned bearing support 1 is 6, is uniformly distributed along the circumference on back-up ring 102.
The material of above-mentioned bearing support 1 is A3 steel.
When installing bearing 2, only need to be placed on bearing hole 101 place smooth for bearing 2, then evenly knock installation and enter, bearing accepts evenly, can not damage bearing and bearing support; During dismounting bearing 2, only need rotate and eject screw 3 and bearing 2 can be ejected from bearing hole 101.
