Specific implementation mode
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
A kind of tautness adjustable axle sleeve disclosed by the utility model, embodiment one：
As shown in Figure 1, include two outer shafts 11 being nested and internal axle sleeve 12, the outer shaft 11 and internal axle sleeve 12 it is same
Flange flange 111/121 is respectively equipped on one end, the flange flange 111 when using installation on the outer shaft 11 is for locking
In mechanical rack, mechanical shaft or shaft pass through internal axle sleeve 12, the appearance of the inner surface and internal axle sleeve 12 of the outer shaft 11
It is corresponding nested taper surface 112/122 between face, the cone of the taper surface 112 and internal axle sleeve 12 of outer shaft 11 as illustrated in the drawing
Shape face 122 be the small one end of diameter downward, the big one end of diameter upward, axially uniformly offers a plurality of prolong on the internal axle sleeve 12
The straight slot 123 of end is reached, is equipped with and adjusts between the flange flange 111 of the outer shaft 11 and the flange flange 121 of internal axle sleeve 12
Adjust bit architecture, occur loosen gap when, by adjusting adjustment location structure by internal axle sleeve 12 into outer shaft 11
It is pressed into, since the pressure that the effect of 112 taper surface 122 of taper surface is pressed into internal axle sleeve 12 acts on taper surface 112, and outer shaft 11
It is fixed structure again, therefore pressure is turned to internal axle sleeve and pressed by taper surface 112, due to offering straight slot 123 on internal axle sleeve 12,
The surface that 12 side wall of internal axle sleeve between straight slot 123 and straight slot 123 is curved inwardly close to shaft or shaft also just solves
Determined solve backlash the problem of, realize the purpose of adjustment.
In the present embodiment, the adjustment location structure includes the flange flange 111 and internal axle sleeve of outer shaft 11 as shown in Figure 1
The threaded hole 132 that is opened up on the flange flange 111 of the elastic washer 131, outer shaft 11 that are arranged between 12 flange flange 121,
The through-hole 133 and be screwed on threaded hole 132 across through-hole 133 that threaded hole 132 opens up are corresponded on the flange flange 121 of internal axle sleeve 12
On bolt 134, as shown in the figure, the flange flange 111 of the outer shaft 11 and 121 opposite face of flange flange of internal axle sleeve 12
Between be equipped with the gasket groove that be embedded in for elastic washer 131, be conducive to the embedded of elastic washer 131 and position, do not deviate by；By turning
Dynamic bolt 134 makes bolt 134 screw togather into threaded hole 132, also can be realized as compression internal axle sleeve；If ordinary circumstance shaft or
The gap occurred by frictional dissipation between shaft and axle sleeve is all not too large, therefore adjustment amplitude generally also very little when adjusting, because
The thickness of this spring washer also very little, therefore the elastic washer 131 can be the spring ring being set on internal axle sleeve 12 or can
Realize the rubber ring of preferable deformation；When in addition being operated for ease of adjustment, adjustment balance, the threaded hole 132, through-hole 133 and spiral shell
The correspondence of bolt 134 is laid with two groups, and adjustment pressure so more balances, when adjustment can two bolts 134 operate simultaneously.To prevent
Impurity can be entered by stating between the flange flange 111 of outer shaft 11 and 121 opposite face of flange flange of internal axle sleeve 12, influence to adjust,
The present embodiment can lean on outer edge to be equipped with sealing ring 14 therebetween, and rubber material can be used in sealing ring 14, and sealing effect is good,
Compression also easy tos produce deformation.
A kind of tautness adjustable axle sleeve disclosed by the utility model, embodiment two：
As shown in Figure 1, include two outer shafts 21 being nested and internal axle sleeve 22, the outer shaft 21 and internal axle sleeve 22 it is same
Flange flange 211/221 is respectively equipped on one end, the flange flange 211 when using installation on the outer shaft 21 is for locking
In mechanical rack, mechanical shaft or shaft pass through internal axle sleeve 22, the appearance of the inner surface and internal axle sleeve 22 of the outer shaft 21
It is corresponding nested taper surface 212/222 between face, the cone of the taper surface 212 and internal axle sleeve 22 of outer shaft 21 as illustrated in the drawing
Shape face 222 be the small one end of diameter downward, the big one end of diameter upward, axially uniformly offers a plurality of prolong on the internal axle sleeve 22
The straight slot 223 of end is reached, is equipped with and adjusts between the flange flange 211 of the outer shaft 11 and the flange flange 221 of internal axle sleeve 22
Adjust bit architecture, occur loosen gap when, by adjusting adjustment location structure by internal axle sleeve 22 into outer shaft 21
It is pressed into, since the pressure that the effect of 212 taper surface 222 of taper surface is pressed into internal axle sleeve 22 acts on taper surface 212, and outer shaft 21
It is fixed structure again, therefore pressure is turned to internal axle sleeve and pressed by taper surface 212, due to offering straight slot 223 on internal axle sleeve 22,
The surface that 22 side wall of internal axle sleeve between straight slot 223 and straight slot 223 is curved inwardly close to shaft or shaft also just solves
Determined solve backlash the problem of, realize the purpose of adjustment.
In the present embodiment, the adjustment location structure includes the flange flange 211 and internal axle sleeve of outer shaft 21 as shown in Figure 1
Internal thread 232 that the madial wall end of the elastic washer 231, outer shaft 21 that are arranged between 22 flange flange 221 is equipped with and
Internal thread 232 is corresponded on the lateral wall of internal axle sleeve 22, matched external screw thread outer 233 is set, when adjustment, directly pass through and rotate inner shaft
Set 22, you can internal axle sleeve 22 is pressed by realization, pressure imbalance when without having to worry about adjustment.As shown in the figure, the outer shaft 21
Flange flange 211 and 221 opposite face of flange flange of internal axle sleeve 22 between be equipped with the gasket groove that is embedded in for elastic washer 231,
The embedded positioning for being conducive to elastic washer 231, does not deviate by；If because friction is damaged between ordinary circumstance shaft or shaft and axle sleeve
Adjustment amplitude generally also very little when it is all not too large to consume the gap occurred, therefore adjusting, therefore the thickness of spring washer also very little,
Therefore the elastic washer 231 can be the spring ring being set on internal axle sleeve 122 or can realize the rubber ring of preferable deformation；Separately
Outside, for convenience of rotation internal axle sleeve 22, the inner shaft, 22 flange flange 221, which is equipped with, to be convenient for turning by being located by connecting with tool
The structure connection structure of dynamic internal axle sleeve 22, concretely the flange flange outer profile of the internal axle sleeve is polygonized structure, as usual
See nut use hexagonal structure, but also other empty slots cooperation structure.To prevent the flange flange 211 of the outer shaft 21
Impurity can be entered between 221 opposite face of flange flange of internal axle sleeve 22, influence to adjust, the present embodiment can be outer therebetween
Edge is equipped with sealing ring 24, and rubber material can be used in sealing ring 24, and sealing effect is good, and compression also easy tos produce deformation.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
