Abstract

The invention discloses a manufacturing method of a tooth difference speed reducer of a double-row planetary gear, belongs to speed reducers, and particularly relates to a speed reducer which is highin precision, large in reduction ratio and easy to manufacture. The problems that a traditional speed reducer is difficult to manufacture and assemble, small in reduction ratio, small in transmissionpower, poor in precision, prone to abrasion and large in weight and size are solved. Two rows of planetary gear sets with the tooth number difference of one tooth or two teeth are adopted for connection, and the large reduction ratio is obtained through the tooth difference. The manufacturing method disclosed by the invention is mainly applied to speed reduction equipment which is small in size, light in weight, high in precision, large in transmission ratio and large in transmission force, and particularly the speed reducer needed by automatic production.

Description

technical field [0001] The present invention belongs to a speed reducer, in particular to a speed reduction device with high precision and large reduction ratio. Background technique [0002] With the continuous improvement of technology and living standards, the demand for reducers in automated production and mechanical equipment is also increasing, especially reducers with small size, simple and reliable structure, high precision, high suburban rate and large reduction ratio. At present, the existing reducers are divided into conventional cylindrical gear reducers, planetary reducers, worm reducers, harmonic reducers, and RV cycloid reducers. The cylindrical gear reducer has a large volume and a small reduction ratio. The planetary reducer is small in size and can support large torque, but the reduction ratio is small. The transmission rate of the worm reducer is low and easy to wear, and the harmonic reducer is small in size and large in transmission ratio, but it is no...
