1. A pressure plate bearing device comprising:
a bearing, and
a pressure plate comprising:
a sleeving hole located around the outside of an outer race of the bearing;
a limiting groove provided in a position where the outer race of the bearing is nested in the sleeving hole; and
a steel ball arranged in the limiting groove;
wherein a connection between the steel ball and the sleeving hole and a connection between the steel ball and the outer race of the bearing at least form an axial limit between the bearing and the pressure plate;
wherein the outer race of the bearing or the pressure plate is provided with a mounting channel in communication with the limiting groove; and
wherein a limiting member configured for limiting and holding the steel ball in the limiting groove is arranged in the mounting channel;
wherein the limiting groove further comprises an annular rolling groove and a groove;
wherein the mounting channel is provided in the pressure plate;
wherein the annular rolling groove is provided in an outer circumferential surface of the outer race of the bearing;
wherein the groove is provided in an inner circumferential surface of the sleeving hole of the pressure plate;
wherein the mounting channel further comprises a radial extension section and an axial extension section,
wherein one end of the radial extension section is connected to the inner circumferential surface of the sleeving hole;
wherein the axial extension section is provided with a mounting hole at an axial end face on at least one side of the pressure plate;
wherein the limiting member is fixed into the axial extension section; and
wherein a ball support is movably arranged in the radial extension section; and a first end of the ball support is provided with a ball socket in rolling contact with the steel ball, and a second end of the ball support abuts against the limiting member for a limit.
