Crucial effect, end cap generallys use cake formula structure in the prior art, and structure is simple, at low cost, but there are weight weights, branch
The disadvantages of supportting intensity difference and poor heat-sinking capability, urgent need will be improved.
Utility model content
The applicant provides a kind of bearing end with assistant reinforcement muscle for the disadvantage in above-mentioned existing production technology
Lid, so as to support raising intensity, meets cooling requirements.
Technical solution used by the utility model is as follows:
A kind of bearing (ball) cover with assistant reinforcement muscle, including end cap ontology, the equal shape in inside and outside side of the end cap ontology
At there is interior concaved circular cambered surface, through-hole is provided in the middle part of end cap ontology, the inner ring of through-hole forms bearing chamber, the end cap sheet positioned at through-hole outer ring
On outside, the first outside of multiple groups radiating ribs are circumferentially arranged at intervals with, are equipped with second between every group of first outside radiating ribs
Outside radiating ribs, it is circumferentially square on the end cap outer body face of the first outside radiating ribs and the second outside radiating ribs outer ring
To multiple groups third radiating ribs are uniformly arranged, seam allowance end is equipped between every group of third radiating ribs；End cap ontology positioned at through-hole outer ring
On medial surface, along the circumferential direction multiple medial support muscle are arranged in uniform intervals, and end cap ontology medial surface outer edge is provided with step
Face is provided with multiple location holes on the step surface, and location hole break-through is in the seam allowance end middle position at the back side.
Its further technical solution is:
Every group of first outside radiating ribs include two rectangular radiating ribs in section, and the section of the second outside radiating ribs is at three
It is angular.
Medial support muscle camber bladed structure, curved end are abutted with interior concaved circular cambered surface.
The length of first outside radiating ribs and the second outside radiating ribs is respectively less than the length of medial support muscle.
The end cap ontology uses gray cast iron HT250.
The beneficial effects of the utility model are as follows:
The utility model is structurally reasonable, by increasing radiating ribs in the outside of bearing (ball) cover, helps to radiate, inside increases
Supporting rib reinforces the rigidity of end cap, reduces its thickness and weight, reduces cost.Simultaneously as the effect of radiating ribs, increases
Heat dissipation area substantially increases the service life of bearing；
The utility model is by the disposable casting and forming of gray cast iron, and easy to process, the material of use is reduced, with the prior art
Middle cake formula structure is compared, and the utility model weight saving 42% reduces end cap production cost；
The utility model heat dissipation area increases 255% compared with cake formula structure in the prior art, and bearing temperature has dropped
12℃；
The design of first outside radiating ribs and the second outside radiating ribs, third radiating ribs and medial support muscle greatly improves
The support strength of end cap, intrinsic frequency increase by 25%, and vibration displacement reduces 37%, so that receiving of the end cap to machine vibration
Power greatly reinforces.
