Abstract
The invention relates to an external-bearing axial adjustment mechanism for a rotating member. The external-bearing axial adjustment mechanism is mainly composed of a spline spindle 1, the rotating member 2, a spline sleeve 3, an adjusting shaft 4, an adjusting arm 5, an adjusting bearing 6 and tapered rollers 7. The spline spindle 1 is connected with the spline sleeve 3 through a spline; the spline sleeve 3 can axially slide on the spline spindle 1; the rotating member 2 is fixedly connected with the spline sleeve 3; an annular groove with a tapered opening is formed in the spline sleeve 3 and is in clearance fit with the tapered rollers 7 through the annular groove; the adjusting bearing 6 is connected to inside of the tapered rollers 7; the adjusting bearing 6 is connected with the adjusting arm 5 through the adjusting shaft 4; and the adjusting arm 5 is connected with an actuator. During working, the rotating member 2 rotates synchronously together with the spline sleeve 3 and the spline spindle 1; the tapered rollers 7 roll along one side of the annular groove of the spline sleeve 3 and the other sides of the tapered rollers do not make contact with the annular groove; and the actuator adjusts the positions of the tapered rollers 7 in the axial direction of the spline spindle 1 through the adjusting arm 5, so that the spline sleeve 3 and the rotating member 2 are pushed to perform axial movement. The external-bearing axial adjustment mechanism for the rotating member has the characteristics that the structure is simple and the bearing is convenient to replace.
Description
Technical field
The present invention relates to the bearing external mechanism for axial adjusting of a kind of revolving part, there is simple in construction, be convenient for changing the feature of bearing.
Background technology
In mechanical design field, spline pair is the design that a kind of conventional revolving part moves axially.For realizing moving axially of revolving part, it is common practice to connect with spline housing for axle and bearing, bearing connect bearing holder (housing, cover), again bearing holder (housing, cover) be connected to actuator, control moving axially of revolving part by adjusting the axial location of bearing holder (housing, cover).
Although this kind of method is simple, if but bearing be damaged, think that replacing must all remove above-mentioned all parts, process is more complicated, consuming time requires great effort again.
Summary of the invention
Problem to be solved by this invention is to provide the bearing external mechanism for axial adjusting of a kind of revolving part, simplifies the Renewal process of bearing, improves work efficiency.
Present invention provide the technical scheme that spline spindle 1 is connected by spline with spline housing 3, spline housing 3 can slide axially on spline spindle 1；Revolving part 2 is fixing with spline housing 3 to be connected；Spline housing 3 is provided with the cannelure of tapered opening, and is coordinated with the rolling of tapered roller 7 gap by cannelure；Connect adjustment bearing 6 in tapered roller 7, regulate bearing 6 and be connected with regulating arm 5 by regulating axle 4；Regulating arm 5 connects actuator.
Above-mentioned a kind of revolving part bearing external mechanism for axial adjusting includes spline spindle 1, revolving part 2, spline housing 3, regulates axle 4, regulating arm 5, regulates bearing 6 and tapered roller 7.
The above-mentioned tapered roller 7 of a kind of revolving part bearing external mechanism for axial adjusting is that clearance-type rolling coordinates with the cannelure of the upper conical opening of spline housing 3, during work, the sidewall of cannelure is along Impact direction one side Structure deformation with on spline housing 3 for tapered roller 7, and opposite side does not contact；
The tapered roller 7 of above-mentioned a kind of revolving part bearing external mechanism for axial adjusting with the cannelure taper fit of the upper conical opening of spline housing 3 as in figure 2 it is shown, r1/r2=R1/R2, it is ensured that tapered roller 3 is coordinate without entirely rolling of inside and outside slippage with cannelure sidewall；
Above-mentioned a kind of revolving part bearing external mechanism for axial adjusting may be designed as single tapered roller 7 and spline housing annular slot fit, it is also possible to two or more along spline housing cannelure circumferencial direction symmetric design, to strengthen support force and to ensure stress balance.

Detailed description of the invention
Embodiment 1:
Referring to Fig. 1, when a kind of revolving part bearing external mechanism for axial adjusting in the present embodiment works, revolving part 2 and spline housing 3, spline spindle 1 synchronous axial system, tapered roller 7 along spline housing 3 side roll of cannelure, opposite side not in contact with, the regulating arm 5 position axially regulating tapered roller 7 along spline spindle 1 is passed through in actuator, thus promoting spline housing 3 and revolving part 2 to carry out axially-movable.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all make within the spirit and principles in the present invention any amendment, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
