Drawings
Fig. 1 is an exploded view of the overall structure of the present invention.
The utility model discloses the name that well reference numeral corresponds:
the self-lubricating device comprises a longitudinal shaft 1, a transverse shaft 2, an O-shaped ring 3, a cross shaft 4, a self-lubricating bush 5, a bush groove 6, a bush axial elastic sheet 7 and a control rod assembly 8.
Detailed Description
The following provides a preferred embodiment of the present invention with reference to the accompanying drawings to explain the technical solutions of the present invention in detail.
The utility model provides a gear-shifting control mechanism with a cross shaft structure, which is matched with a gear-shifting control rod assembly 8; the gear shifting control mechanism of the cross shaft structure comprises: vertical axis 1, horizontal axis 2, cross 4, self-lubricating bush 5.
The longitudinal axis 1 and the transverse axis 2 are mutually crossed, and the longitudinal axis 1 and the transverse axis 2 are respectively arranged in two directions of a cross shaft 4; the freedom degree in the direction of X, Y, Z is restricted by matching the inner hole of the cross shaft 4 through the cross matching of the longitudinal shaft 1 and the transverse shaft 1.
A bush groove 6 is formed on the self-lubricating bush 5, and a bush axial elastic sheet 7 is matched with the self-lubricating bush 5; the bush axial spring 7 is arranged between the cross shaft 2 and the self-lubricating bush 5, and the self-lubricating bush 5 is sleeved on one end of the cross shaft 2 close to the cross shaft 4.
The self-lubricating bush 5 is formed by injection molding of a self-lubricating material POM and is assembled in an inner hole of the cross shaft 4. The cross 4 is injection molded from PA66GF 50. An O-shaped ring 3 is arranged between the self-lubricating bushing 5 and the cross shaft 4.
The self-lubricating bushing 5 is designed in a radial bushing groove 6 and a bushing axial elastic sheet 7, so that a radial and axial movement gap is eliminated, and the problem of a fit gap is solved more effectively by the design of transversely assembling and pre-tightening an O-shaped ring 3.
In order to meet the requirements of front and back shifting and left and right movement, the operating rod assembly 8 is connected with the transverse shaft 2 through a side hole, the operating rod assembly is in clearance fit with the transverse shaft 2, the self-lubricating bushing 5 in the middle is in transition connection, the bushing plays a role in reducing friction resistance, and front and back shifting and rotary movement around the transverse shaft can be easily achieved. The cross shaft 2 is in cross connection with the longitudinal shaft 1 through the cross shaft 4, and the left and right gear shifting can be easily realized to rotate around the longitudinal shaft 1 by adopting clearance fit.
The bush groove 6 of the self-lubricating bush 5 is adjusted to adapt to the dimensional tolerance in the diameter direction and eliminate the axial clearance in order to eliminate the tolerance of the inner hole of the operating rod assembly and the tolerance of the outer circle of the transverse shaft 2, namely the operating rod assembly moves up and down along the metal rod. The bush axial spring piece 7 eliminates the clearance of the inner side width dimension tolerance of the operating rod assembly and the cross axle width dimension tolerance, namely eliminates the movement clearance of the cross axle 4 along the left and right sides of the transverse shaft 2.
