Bearing production method

Abstract

The invention relates to a bearing manufacturing method. The bearing manufactured by the method comprises an outer race, rolling elements and an inner race. The rolling elements are evenly arranged between the outer race and the inner race. The outer race of the bearing is stamped so that the end face of the outer race bends inwards in the radial direction to form a stop collar and to hold up the rolling elements from moving in the axial direction; the rolling elements are matched with and connected with the inner race and the outer race in a sliding way. Both ends of the rolling elements are arranged in the stop collar formed by bending the outer race inwards, respectively. When the inner race of the bearing rotates with an axis, the rolling elements move around the axis along the stop collar formed by bending the outer race of the bearing inwards. As both ends of the rolling elements of the bearing provided by the invention are movably arranged, the rolling elements can rotate around the axial lead of the bearing so that no clearance exists between the rolling elements. In addition, the rolling elements are positioned primarily by the radial force produced when the outer race of the bearing is bent inwards to form the stop collar through axial holding-up of the stop collar, thus effectively improving the carrying capacity and the use characteristics of the bearing and prolonging the service life of the bearing.

Description

technical field [0001] The invention relates to a production method of a bearing. Background technique [0002] Bearings are widely used in the mechanical field to support the shaft. It can guide the rotation of the shaft and can also bear the idling parts on the shaft. It is generally composed of an outer ring, a rolling element, a cage and an inner ring. The function of the inner ring is to cooperate with the The shaft matches and rotates together with the shaft. The function of the outer ring is to cooperate with the bearing seat and play a supporting role. In production, holes are usually drilled at equidistant distances on the cage and connected to the rolling elements by screws so that the rolling elements are evenly distributed. Between the inner ring and the outer ring, it can be seen that the structure of the bearing makes the high-speed operation of the shaft drive the bearing to rotate during use, and the direct contact between the cage and the bearing seat makes ...

[0002] Bearings are widely used in the mechanical field to support the shaft. It can guide the rotation of the shaft and can also bear the idling parts on the shaft. It is generally composed of an outer ring, a rolling element, a cage and an inner ring. The function of the inner ring is to cooperate with the The shaft matches and rotates together with the shaft. The function of the outer ring is to cooperate with the bearing seat and play a supporting role. In production, holes are usually drilled at equidistant distances on the cage and connected to the rolling elements by screws so that the rolling elements are evenly distributed. Between the inner ring and the outer ring, it can be seen that the structure of the bearing makes the high-speed operation of the shaft drive the bearing to rotate during use, and the direct contact between the cage and the bearing seat makes the cage easy to be worn, and the wear of the cage The deformation will cause deviation between the center of motion and the axis of the rolling elements fixed on it or the rolling elements will fall off from the cage, which will affect the normal use of the bearing and greatly affect the service life of the bearing. In addition, this method will also cause various There is a gap between the rolling elements, that is, the number of rolling elements is small, which greatly limits the load capacity and performance of the bearing
