Abstract

The invention discloses a high-durability single-wave-line speed reduction bearing which comprises an input shaft. The input shaft comprises a first installation part, an eccentric part and a second installation part. The periphery of the first installation part is movably sleeved with a first shell, an avoiding groove is formed in the first shell, the periphery of the eccentric part is movably sleeved with a driving disc, and the driving disc is located in the avoiding groove. A ball mechanism is arranged between the driving disc and the avoiding groove. The periphery of the second installation part is movably sleeved with a second shell, and multiple ball positioning grooves are formed in the end, opposite to the driving disc, of the second shell in the circumferential direction. An outer cycloid groove is formed in the end, opposite to the second shell, of the driving disc. First balls are arranged in the ball positioning grooves, one ends of the first balls are located in the ballpositioning grooves, and the other ends of the first balls are located in the outer colloid groove. The high-durability single-wave-line speed reduction bearing is high in durability, low in noise andlong in service life.

Description

technical field [0001] The invention relates to the field of reduction bearings, in particular to a high-durability single-wave linear reduction bearing. Background technique [0002] In the production process of mechanical equipment, it is necessary to adjust the rotational speed ratio of the two stages through the reducer, so as to reduce the high-speed rotation of the upper-stage equipment, so as to obtain a larger torque. Existing deceleration bearings generally adopt the gear meshing mode for transmission, and the deceleration effect is realized through the tooth difference generated between the gears. [0003] Greater wear occurs between the gears, resulting in faster wear of the gears. When the worn gears are in transmission, they will generate greater noise, reduce the transmission efficiency and transmission accuracy, shorten the service life of the bearings, and increase the equipment cost. use cost. Contents of the invention [0004] The purpose of the present...
