Description
Technical field
The utility model relates to a kind of bearing, and more particularly, it relates to a kind of novel resistance to compression bearing.
Background technique
Existing bearing generally only has row's steel ball, the lifting surface area of the inside and outside ring of its steel ball and bearing is less, and the pressure that causes the steel ball of bearing to bear is very big, and under long-time pressure, steel ball is yielding, cause the rolling of steel ball limited, thereby affect the rolling effect of bearing.
At present, (Chinese patent that application number is 201320438619.1 discloses a kind of resistance to compression bearing) on market, it comprises outer shroud and interior ring, between outer shroud and interior ring, be provided with main steel ball, inner and the outside main slot rolling rolling for main steel ball that is provided with of interior ring at outer shroud, it is characterized in that: be respectively equipped with the second slot rolling and the 3rd slot rolling on the both sides of the described main slot rolling of outer shroud, on described interior ring outside, be provided with the 4th slot rolling and the 5th slot rolling that match with the second slot rolling and the 3rd slot rolling, and be equipped with secondary steel ball between the second slot rolling and the 4th slot rolling and the 3rd slot rolling and the 5th slot rolling, the diameter of described main steel ball is greater than the diameter of secondary steel ball.Although this resistance to compression bearing reduces the pressure that bears of each steel ball; thereby improve the bearing capacity of bearing; improve the working life of bearing; but bearing cannot effectively be protected steel ball; the Main Function that still can be under pressure on steel ball, steel ball is still than being easier to distortion, thereby anti-pressure ability is limited; and three groups of steel balls have increased friction, the burden while making bearing running.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of anti-extrusion ability strong, the bearing of burden can not increase bearing running time.
For achieving the above object, the utility model provides following technological scheme: a kind of novel resistance to compression bearing, comprise outer shroud and interior ring, and between described outer shroud and interior ring, be provided with steel ball; Described at outer shroud inside and the outside slot rolling rolling for steel ball that is equipped with of interior ring; Described steel ball is provided with retainer; Described outer shroud is made up of two coaxial annulus that arrange; Described two annulus interconnect and form by several trapezoid blocks; Described every two trapezoid blocks are oppositely arranged, and its two relative surface elastics connect, and described trapezoid block inclined-plane is all tangent with steel ball; Between described every two adjacent trapezoid blocks, elasticity connects.
By adopting technique scheme, in the time of bearing pressurized, pressurized position is subject to positive pressure, make under pressure trapezoid block pressurized along alignment both sides in outer ring separately, inwardly ring direction motion simultaneously, trapezoid block inclined-plane is along sliding with steel ball surface direction tangential, effectively convert the pressure on a part of vertical direction to pulling force in substantially horizontal, because elasticity between described every two trapezoid blocks connects, thereby generation elastic force, this elastic force will offset with the pulling force of being changed by pressure, thereby on steel ball surface, suffered pressure will reduce greatly, just be not easy to occur being under pressure effect, cause the problem of steel ball generation deformation, can not affect bearing normally works.In the time that bearing is not under pressured state, pressure is cancelled, and is subject to elastic force effect, make adjacent trapezoid block mutually recover motion, trapezoid block inclined-plane is along moving away from interior ring with steel ball direction tangential, make trapezoidal again with together with, the steel ball impact that can not be under pressure, it is normal that bearing recovers.
The utility model is further set to: between described every two trapezoid blocks, use shell fragment to connect, and be V-arrangement shape.
By adopting technique scheme, be fixedly connected on trapezoid block and the setting for V-arrangement shape by shell fragment, the suffered elastic force of trapezoid block is maximized, bearing anti-pressure ability is strengthened, increase the performance of bearing integral.
In the utility model embodiment: trapezoid block inclined-plane is greater than steel ball radius; Trapezoid block is tall and big in diameter of the steel ball; Trapezoid block quantity is the twice of steel ball quantity; Shell fragment quantity is three times of steel ball quantity; Shell fragment and trapezoid block use and are welded and fixed; Area that shell fragment forms is greater than interval area between trapezoid block; Shell fragment is made up of stainless steel material.

Embodiment
Referring to figs. 1 through Fig. 3, the utility model resistance to compression bearing embodiment is described further.
As shown in Figure 1 to Figure 3, a kind of novel resistance to compression bearing, comprises outer shroud 1 and interior ring 2, between described outer shroud 1 and interior ring 2, is provided with steel ball 3; It is described that at outer shroud 1, inner and interior ring 2 outsides are equipped with the slot rolling 4 that confession steel ball 3 rolls; Described steel ball 3 is provided with retainer 5; Described outer shroud 1 is made up of two coaxial annulus that arrange; Described two annulus interconnect and form by several trapezoid blocks 12; Described every two trapezoid blocks 12 are oppositely arranged, and its two relative surface elastics connect, and described trapezoid block 12 inclined-planes are all tangent with steel ball 3; Between described every two adjacent trapezoid blocks 12, elasticity connects.Between described every two trapezoid blocks 12, use shell fragment to connect; Described shell fragment 11 is V-arrangement shape.
By adopting technique scheme, in the time of bearing pressurized, pressurized position is subject to positive pressure, make under pressure trapezoid block 12 pressurizeds along alignment both sides in outer ring separately, inwardly ring direction motion simultaneously, trapezoid block 12 inclined-planes slide along the surperficial direction tangential of steel ball 3, shell fragment 11 also stretches to both sides pressurized, shell fragment 11 is gradually converted into self elastic force by pressure in stretching process, until pressure is all converted into just stop motion of elastic force, effectively convert the pressure on a part of vertical direction to pulling force in substantially horizontal, the elastic force of shell fragment 11 will offset with the pulling force of being changed by pressure, thereby the steel ball 3 upper suffered pressure in surface will reduce greatly, just be not easy to occur being under pressure effect, cause steel ball 3 that the problem of deformation occurs, can not affect bearing normally works.In the time that bearing is not under pressured state, pressure is cancelled, be subject to the elastic force effect of shell fragment 11, make adjacent trapezoid block 12 mutually recover motion, trapezoid block 12 inclined-planes are along moving away from interior ring 2 with steel ball 3 direction tangential, make trapezoid block 12 again with together with, steel ball 3 impact that can not be under pressure, it is normal that bearing recovers.And shell fragment 11 area that forms is greater than the area in adjacent two trapezoid block 12 gaps that form, the outer shroud 1 that can make shell fragment 11 and trapezoid block 12 form forms sealing state, thereby has avoided dust in air to enter bearing, has extended the working life of bearing.
In sum, the utility model is by the setting of trapezoid block 12 and shell fragment 11, and between mating reaction to have realized the anti-extrusion ability of bearing strong, effectively decompose suffered pressure, make stressed reducing on steel ball, burden can not increase bearing running time, long service life, the comprehensive performance that promotes bearing.
The above makes preferred implementation of the present utility model, does not depart from for the person of ordinary skill of the art under the prerequisite of the utility model principle, can also make some modification and improvement, and these also should be considered as protection domain of the present utility model.
