Enhanced heavy-duty deep groove ball bearing

Abstract

The invention provides an enhanced heavy-duty deep groove ball bearing. The bearing comprises an outer ring, an inner ring, rolling bodies and retainers, wherein the rolling bodies are arranged in a spherical pocket hole formed by two retainers; the inner ring and the outer ring are respectively arranged on the inner and outer sides of an annular body formed by the rolling bodies and the retainers; and a roller way of the inner ring and a roller way of the outer ring are respectively contacted with the rolling bodies. Platy rivets are adopted, and the two ribbon retainers are not directly contacted during riveting, so that inner space is increased; the enhanced heavy-duty deep groove ball bearing is provided with two to three more rolling bodies than the conventional deep groove ball bearing, and the diameter of the rolling bodies is one to two times larger than that of the rolling bodies of the conventional deep groove ball bearing, so that the bearing capacity of the bearing is 20 to 30 percent higher than that of the deep groove ball bearing of the same overall dimension, and the rated load of the bearing is equivalent to that of a cylindrical roller bearing of the same overall dimension; meanwhile, the limit rotating speed of the bearing is improved, and the rotating speed of the series bearing is 20 to 30 percent higher than that of the cylindrical roller bearing.

Description

(1) Technical field [0001] The invention relates to the fields of bearing structure design and bearing ring processing, in particular to a heavy-duty deep groove ball bearing. (2) Background technology [0002] At present, it is difficult for the cylindrical roller bearings in the rear axle gearboxes of heavy-duty trucks in my country to truly meet the high-speed and heavy-duty performance requirements. However, many well-known foreign bearing companies such as NSK, SKF, and FAG are developing and manufacturing new structures. Reinforced heavy-duty deep groove ball bearing series products, there is no such product in my country at present, and it cannot replace the cylindrical roller bearings used in road transport vehicles to meet the needs of its high-speed development. (3) Contents of the invention [0003] The purpose of the present invention is to provide a reinforced heavy-duty deep groove ball bearing which not only has the high-speed performance of a ball bearing, b...
