Problems solved by technology

However, for cylindrical roller bearings with large batches, high operating speed, impact resistance and stability, the traditional copper and nylon cages cannot meet the requirements of the equipment.
Although the copper cage has good impact strength, the processing technology is complicated, which is not conducive to mass production and processing and the cost is high; while the nylon cage has a high working speed and is easy to mass produce, but because of its brittle material, the impact resistance weak strength

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 2 As shown, the stamping cage of the new high-strength and high-stability cylindrical roller bearing is made of a steel plate with a thickness of 1.5mm. The pocket hole is in the form of a square hole, its width is designed to be 0.985 times the diameter of the roller, and its length is designed to be 1.02 times the length of the roller.

[0012] Apply the cage prepared above to figure 1 On the cylindrical roller bearing shown, the cylindrical roller bearing includes an outer ring 1 , a retaining ring 2 , cylindrical rollers 3 , a cage 4 and an inner ring 5 . The cylindrical rollers 3 are distributed on the raceway formed by the outer ring 1 and the inner ring 5 and are evenly separated by several pockets on the cage 4; The groove is in interference contact, so as to ensure that the outer ring 1 is not separated from other parts.

Abstract

The invention relates to a novel high strength and high stability stamping retainer of a cylinder roller bearing. The retainer uses the steel plates with thickness being not more than 2mm as the materials, thus fully reducing the dead weight of the bearing and improving the rotating speed of the bearing. The pockets and the appearance of the retainer are stamped once and finally undergo secondary reshaping and phosphating. The pockets of the retainer are square, thus reducing the machining difficulty and fully meeting the requirement of mass production. The width of the pockets of the retainer is 0.985 times the diameter of the roller in design and the length thereof is 1.02 times that of the roller in design, thus ensuring the external diameter of the roller set not to interfere with the outer ring flange, ensuring final smooth assembly of the bearing, tightly pressing sag of the retainer and effectively improving the stability of operation.

Description

technical field [0001] The invention relates to a novel high-strength and high-stability cylindrical roller bearing stamping cage. Background technique [0002] Cylindrical roller bearings are bearings that can withstand large radial loads and a small amount of axial loads. They have high load carrying capacity and are also suitable for high speeds. It is widely used in various mechanical parts and plays an extremely important role. The cages are mostly made of brass and nylon materials. However, for cylindrical roller bearings with large batch size, high operating speed, impact resistance and stability, the traditional copper and nylon cages can no longer meet the requirements of the equipment. Although the copper cage has good impact strength, the processing technology is complicated, which is not conducive to mass production and processing and the cost is high; while the nylon cage has a high working speed and is easy to mass produce, but because of its brittle material,...
