Description
Technical field
The present invention relates to shift fork technical field, specifically refer to a kind of floating shift fork driving mechanism be applied on rotation major axis.
Background technique
Transmission machinery or equipment Industry, in rotation transmission process, rotatingshaft all can have a small amount of distortion or bending, especially major axis is rotated, distortion or bending even more serious in rotation transmission process, even can affect driving mechanism and rotate the transmission on major axis, to overhaul or to eliminate distortion or just can remain in operation after bending, and then have influence on the runnability of whole machine or equipment.For this kind of situation, be extremely extremely at present, in industry or market does not also have and a kind ofly can eliminate or prevent major axis in rotation transmission process distortion or bending, and the major axis technological scheme that still can run well when rotating transmission process distortion or bending or method appearance.
Summary of the invention
The object of this invention is to provide a kind of structure simple, cost is low, easy to use, is applied to and rotates on major axis, major axis can be prevented in the distortion or bending of rotation transmission process, and still can the floating shift fork driving mechanism of smooth and easy transmission when major axis rotation process produces distortion or be bending.
To achieve these goals, the present invention designs a kind of shift fork driving mechanism that floats, it comprises rotation major axis, drive wheel and bearing, drive wheel band dynamic bearing rotates on rotation major axis, also comprise thrust axis, fixing device and mobile plate, described mobile plate is provided with the circular hole matched with bearing outer ring, described bearing outer ring is located in the circular hole of mobile plate, inner ring is enclosed within and rotates on major axis, is provided with fixing device, is connected between mobile plate and fixing device by thrust axis above mobile plate, thrust axis is two, lays respectively at the both sides of rotating major axis.
Described mobile plate is provided with the long-round-shape through hole matched with thrust axis, and one end of thrust axis is connected with fixing device, and the other end inserts in long-round-shape through hole.
Described fixing device is preferably fixed plate, and other also can be adopted if fixed base, fixing rod etc. are as fixing device.
Described bearing is deep groove ball bearing.
Described rotation major axis is circular shaft or square shaft.
The present invention floats the beneficial effect of shift fork driving mechanism: the present invention's shift fork driving mechanism that floats utilizes fork principle, through conceiving cleverly, be applied to rotate in the transmission device on major axis, produce when being out of shape or bending in rotation major axis operation process, can float to producing the direction be out of shape or bend, this effectively can not only prevent rotating major axis in rotation process, produce distortion or bending, and rotation major axis produces in rotation process distortion or bend in also can transmission smooth and easy, thus, the transmission device making to install additional this floating shift fork driving mechanism in rotation major axis operation process can transmission smooth and easy, and the present invention's shift fork driving mechanism structure of floating is simple, cost is low, be suitable for rotating transmission field at major axis extensively to promote the use of.
accompanying drawing illustrates:
Fig. 1 is that the present invention floats the structural representation of shift fork driving mechanism;
Fig. 2 is A-A cross-sectional view in Fig. 1;
Fig. 3 is B-B cross-sectional view in Fig. 1;
Fig. 4 is that the present invention floats the cross-sectional view of shift fork driving mechanism quick condition.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with specific embodiment and accompanying drawing, structural principle of the present invention is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of shift fork driving mechanism that floats, it comprises rotates major axis 1, drive wheel 6 and bearing 7, drive wheel 6 is with dynamic bearing 7 to rotate on rotation major axis 1, the shift fork driving mechanism that floats also comprises thrust axis 2, fixing device 3 and mobile plate 5, described mobile plate 5 is provided with the circular hole matched with bearing 7 outer ring, described bearing 7 outer ring is located in the circular hole of mobile plate 5, inner ring is enclosed within and rotates on major axis 1, fixing device 3 is provided with above mobile plate 5, connected by thrust axis 2 between mobile plate 5 and fixing device 3, thrust axis 2 is two, lay respectively at the both sides of rotating major axis 1, described mobile plate 5 is provided with the long-round-shape through hole 4 matched with thrust axis 2, one end of thrust axis 2 is connected with fixing device 3, the other end inserts in long-round-shape through hole 4.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, described fixing device 3 is fixed plate, and fixed plate is provided with transmission device, and transmission device is driven by driving mechanism and drives the shift fork driving mechanism that floats at rotation major axis upper driving.
As shown in Figure 2, described bearing 7 is deep groove ball bearing.
As shown in Figure 3, Figure 4, described rotation major axis 1 is square shaft.
As shown in Figure 4, when rotation major axis produces distortion or is bending in operation process, the present invention floats the meeting of shift fork driving mechanism one side along with distortion or bending generation floating continuation transmission, on the other hand because thrust axis 2 maintains static, effectively can prevent rotating major axis 1 and produce distortion or bending dynamic turning in journey, Fig. 4 be the present invention float shift fork driving mechanism rotate in major axis 1 operation process produce distortion or bending time quick condition schematic diagram.
