Abstract
The utility model discloses a rolling friction device which comprises a device body (1) which is provided with a rectangular tope surface and served as a guide rail, and a slide plate component (2) clamped at the upper part of the device body (1) through a notch, wherein the both side walls of the notch of the slide plate component (2) are provided with circular arc-shaped chutes and ball channels communicated with the circular arc-shaped chutes and arranged in the slide plate component (2); both side walls of the guide rail are provided with spherical arc-shaped grooves which correspond to the circular arc-shaped chutes on the side of the notch; the circular arc-shaped chutes on the side wall of the notch on one side, the spherical arc-shaped grooves on the side wall of the guide rail and the ball channels form a smooth ball track; and balls are fully distributed in the track. The rolling friction device presents a motion friction reduction design according to the friction force characteristic, replaces sliding friction with rolling friction, effectively improves the stress state of the device body and a slide plate and reduces the friction consumption to the device body and the slide plate, thereby improving the service life of the device body and the component.
Description
Technical field
The present invention relates to a kind of rolling antifriction apparatus, more particularly, it relates to a kind of rolling antifriction apparatus that has ball.
Background technique
At present, various traditional sliding devices have been used in the machinery industry, they are that body is fixed, slide plate is arranged to form of grooves, and notch is downward, and slide plate is connected on the body, such sliding device is that body directly contacts slip with slide plate, it is very big to rub, and very big to the loss of body and slide plate, working life is not long.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of simple in structure, be easy to manufacturing, easy to use, the rolling antifriction apparatus that can reduce to rub, improve body and slide plate working life.
In order to achieve the above object, a kind of rolling antifriction apparatus of the present invention comprises having the body that rectangular top is used as guide rail, and the skateboard component that is stuck in described body upper with recess.Wherein, offer arc groove respectively on its recess both sides sidewall of described skateboard component and be communicated with the ball channel that is positioned at the skateboard component body with arc groove; Arc groove on the corresponding described recess sidewall of described guide rail both sides sidewall offers the sphere curve bath; Be positioned at arc groove and sphere curve bath on the described guiding cheekn and the level and smooth ball orbit of ball channel formation on the described recess sidewall of a side, in described track, be covered with ball.
Above-mentioned rolling antifriction apparatus, improvement are that skateboard component comprises that the panel on top and bottom are positioned at two ball housings that both sides constitute recess.Described arc groove is positioned on the described ball housing, and described ball channel is positioned at described ball housing.In addition, under the optimal way, panel and ball housing are one by bolt.
In order to address the above problem, the present invention proposes a kind of motion antifriction design according to the frictional force characteristic, replace sliding friction with rolling friction, effectively improve the stress of body and slide plate, reduce frictional loss body and slide plate, and the working life of therefore improving body and assembly.
Description of drawings
Fig. 1 is the schematic top plan view of body when combining with slide plate;
Fig. 2 is the cross-sectional view of A-A direction among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, a kind of rolling antifriction apparatus, below body 1 is rectangular track, track is wide at the top and narrow at the bottom, and the bilateral symmetry of wide section part processes the circular groove track on middle body 1, and notch is towards both sides, the skateboard component 2 that body 1 moves for orbital path is installed in body 1 top, skateboard component 2 is clamping with the Placement of body, and skateboard component 2 is recess shape, and the recess groove is stuck in last wide section part of body 1.
The skateboard component 2 that ball 3, ball housing 4, bolt 5 and square panel 6 are formed snaps fit onto on the body 1, the part that ball housing 4 is contacted with body 1 just in time is embedded in the groove on the body 1, promptly allow ring track and the circular groove on the body 1 in the ball housing 4 coincide, ball 3 can freely be rolled in the groove of ball housing 4 and body 1.In the using process, roll in the annular channels that ball 3 is formed along the ring track of the groove of body 1 and ball housing 4,, drive skateboard component 2 body 1 cofree moving along with the rolling of ball 3.
Claims (3)
1. rolling antifriction apparatus comprises having the body (1) that rectangular top is used as guide rail, and is stuck in the skateboard component (2) on described body (1) top with recess, it is characterized in that,
