Abstract
The utility model discloses a linear bearing, round guide rail with advantages of simple structure, long service life and small resistance. The linear bearing disclosed by the utility model comprises a ball and a shaft sleeve, the ball tiers are arranged on the inner circumference of shaft sleeve along the shaft direction in turn, both ends of the ball tier is respectively provided with a holding frame, and a spacing sleeve is arranged between the balls of the ball tiers. The round guide rail base is connected to a shaft, and the linear bearing is arranged between the shaft and a shell. The utility model does not only enhance the moving velocity and reduce the noise but also prolongs the service life and enhances the transmission accuracy.
Description
Technical field
The utility model relates to the mechanical transmissioning technology field, in particular, relates to a kind of linear bearing and round guide thereof.
Background technique
Linear bearing mostly is and arranges the multiple row ball vertically in axle sleeve at present, wherein ball is classified the closely order arrangement of a plurality of balls as, because ball closely contacts, wearing and tearing appear in the high speed operation process easily, but also produce a large amount of heat, influence movement velocity like this, and produce big noise simultaneously.Use the round guide of above-mentioned linear bearing manufacturing to have above-mentioned defective equally.
The model utility content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of simple in structure, the life-span is long, resistance is little linear bearing and round guide are provided.
The utility model linear bearing is achieved by following technical proposals, comprises ball and axle sleeve, and the axle sleeve inner peripheral surface is arranged in order the ball row vertically, and described ball row two ends are respectively arranged with retainer, are provided with spacer between the described ball row ball.
The utility model linear bearing, the described retainer outside is respectively arranged with fixed plate; The described fixed plate outside is respectively arranged with dust cover.
The utility model round guide base is connected with axle, between described axle and housing, be provided with above-mentioned linear bearing, be that the axle sleeve inner peripheral surface is arranged in order the ball row vertically, described ball row two ends are respectively arranged with retainer, are provided with spacer between the described ball row ball.
The ball row are owing to increased spacer structure in the utility model, ball total quantity required in the axle sleeve is reduced, and then gross weight reduces, and the resistance in the axle sleeve moving process reduces thereupon, and owing to do not rub between the ball, effectively reduce the wearing and tearing of ball, not only improved movement velocity, reduced noise, and prolonged working life, improved transmission accuracy, spacer has heat insulation function, can play the purpose that increases the service life equally.
Description of drawings
Fig. 1 is the structural representation of linear bearing,
Fig. 2 is the structural representation of round guide.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, comprise ball 5 and axle sleeve 3, axle sleeve 3 inner peripheral surfaces are arranged in order the ball row of being made up of a plurality of balls 5 vertically, and a plurality of ball row form circumferential surface; Ball row two ends are respectively arranged with retainer 6, are provided with spacer 4 between the ball of ball row.Be respectively arranged with fixed plate 2 in the inboard retainer of axle sleeve 3 both ends of the surface 6 outsides, the doughnut-shaped steel plate that described fixed plate generally adopts size and axle to adapt; Be respectively arranged with dust cover 1 in the inboard fixed plate of axle sleeve 3 both ends of the surface 3 outsides, described dust cover is a size and an annular that adapts.
As shown in Figure 2, base 14 is connected by screw 15 with axle 12, spools 12 and housing 11 between be provided with as shown in Figure 1 linear bearing 13.
Claims (4)
