Abstract
The utility model relates to a punching bowl shape maintaining rack pushing center adjustable roller bear, comprising a seat ring, a roller, a maintaining rack and a shaft ring, wherein the maintaining rack is bowl shaped, a locking port of the maintaining rack makes the shaft ring and the roller an inseparable assembly. The beneficial effect of the utility model is that the successful invention and application of the bowl shaped punching maintaining rack pushing center adjustable roller bear create a considerable economic benefit, fill the researching blank of such kind of bear in China, and increase the product competition ability of the company. Compared with a existent rack structure the bear has a low cost and high rotary speed, whose burden is increased by 15% and life is prolonged by two times, with a high reliability and strong stability, easy to be detached and maintained.
Description
Technical field
The utility model retainer relates to a kind of self-aligning thrust roller bearing.Be widely used in metallurgy industry and universal machine.
Background technique
At present, self-aligning thrust roller bearing commonly used is made up of seat ring, blowout patche, roller, retainer and lining five big parts, and retainer is casting brass car system solid cage, makes retainer, roller and blowout patche form an inseparable assembly by lining.Because lining is a thin-wall part, therefore exist defectives such as processing, trap difficulty, because the retainer material is a casting brass, the bearing cost is improved greatly in addition.
Summary of the invention
At the deficiency of above-mentioned bearing structure, the purpose of this utility model proposes a kind of bowl-type pressing cage self-aligning thrust roller bearing exactly, has adopted a kind of brand-new punching press bowl-type retainer structure, unless the retainer damage, roller can not drop out.Can bear heavier axial load, also can bear radial load, have the self-aligning performance.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of punching press bowl-type retainer self-aligning thrust roller bearing, form by seat ring 1, roller 2, retainer 3 and blowout patche 4, retainer 3 is a bowl-type, and the fore shaft of retainer 3 makes retainer 3 cover into an inseparable assembly to blowout patche 4, roller 2.
The beneficial effects of the utility model are: compare that entity shelf structure bearing cost is low, rotating speed is high, load has improved 15%, the life-span prolongs 2 times, and reliability height, stability are strong.Be easy to dismounting and maintenance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. seat ring, 2. roller, 3. retainer, 4. blowout patche.
Embodiment
As shown in Figure 1, the utility model is made up of seat ring 1, roller 2, retainer 3 and blowout patche 4, and retainer 3 is a bowl-type, and the fore shaft of retainer 3 makes retainer 3 cover into an inseparable assembly to blowout patche 4, roller 2.The utility model has not only satisfied user's usage requirement, but also has solved the deficiency of aspects such as processing and cost well.
