Device and method for filling solid lubricant on spherical sub-textured surface

Abstract

The invention provides a solid lubricant filling device and method for a spherical pair structure surface. The solid lubricant filling device comprises a clamping mechanism, a pressurizing mechanism,a first driving mechanism, a second driving mechanism and a heating mechanism, wherein the clamping mechanism is used for clamping workpieces; the pressurizing mechanism includes a hydraulic chuck anda plurality of spherical clamping plates, the hydraulic chuck comprises a chuck body and a plurality of movable jaws, the spherical clamping plates correspond to the movable jaws one to one, and thespherical clamping plates are mounted on the movable jaws; the first driving mechanism is used for driving the pressurizing mechanism to operate; the second driving mechanism is used for driving the clamping mechanism to move so that the workpieces can move among the multiple spherical clamping plates; and the heating mechanism wraps the clamping mechanism and the pressurizing mechanism and is used for heating and thermal insulation of the workpieces. According to the solid lubricant filling device and method for the spherical pair structure surface, the workpieces are clamped by the clampingmechanism, and spherical pair surfaces of the workpieces are uniformly pressurized by the spherical clamping plates of the pressurizing mechanism, so that the spherical pair structure surfaces are filled with a solid lubricant, and the spherical pair structure surfaces can be uniformly filled with the solid lubricant.

Description

technical field [0001] The invention relates to the field of lubricant filling on textured surfaces, in particular to a device and method for filling solid lubricants on spherical sub-textured surfaces. Background technique [0002] With the rapid development of industrial technology, the spherical pair as a kind of kinematic pair is more and more widely used in various mechanical systems. For example, the joint bearing is a kind of spherical sliding bearing, which has a simple and compact structure and a strong bearing capacity. The spherical pair can perform low-speed swing and tilt motion within a certain angle range, so it is widely used in aerospace, rail transportation and military equipment and other fields. As the demand for spherical plain bearings gradually increases, the requirements for the reliability and wear resistance of spherical plain bearings are also getting higher and higher. Some spherical plain bearings working under harsh working conditions such as ...

Problems solved by technology

This method is to complete the filling process at room temperature, which cannot fully fill and solidify the solid lubricant, and the device uses mechanical transmission, the overall equipment is relatively complicated, and it is difficult to promote industrialization

[0005] The traditional filling method can only fill the solid lubricant on the plane texture surface, and generally fill the solid lubricant on the spherical surface texture by manual filling. This method is not only low in filling efficiency, but also labor-intensive, and cannot achieve the desired filling effect.
