Problems solved by technology

[0002] In the reducer family, the planetary reducer is widely used for its small size, high transmission efficiency, wide deceleration range, high precision and many other advantages. However, when the transmitted power is large, it is necessary to increase the weight of each part of the reducer. In order to increase the reduction ratio, the size and weight of the reducer will inevitably increase, and it cannot be installed in small equipment, which does not conform to the current development trend of equipment miniaturization.

Abstract

The invention relates to a bevel gear staggered tooth speed reducer. The bevel gear staggered tooth speed reducer comprises a machine shell, a planet carrier output shaft, at least three output conical planetary gears, an upper conical gear, a lower conical gear and a driving mechanism, wherein output shaft mounting holes are coaxially formed in the top and the bottom of the machine shell correspondingly; the upper end and the lower end of the planet carrier output shaft are coaxially and rotationally connected with the upper output shaft mounting hole and the lower output shaft mounting holecorrespondingly, and at least three connecting shafts extending in the radial direction of the planet carrier output shaft are arranged on the periphery of the planet carrier output shaft at equal intervals in the circumferential direction; the at least three output conical planetary gears are coaxially and rotatably mounted on the connecting shafts in a one-to-one correspondence manner; upper inner conical teeth meshing with the output conical planetary gears are arranged on the inner edge of the lower end of the upper conical gear; lower inner conical teeth meshing with the output conical planetary gears are arranged on the inner edge of the upper end of the lower conical gear, and the number of the upper inner conical teeth is consistent with that of the lower inner conical teeth; and the driving mechanism is installed on the machine shell, the driving end of the driving mechanism extends into the machine shell and is in transmission connection with the upper conical gear and the lower conical gear, and the driving mechanism is used for driving the upper conical gear and the lower conical gear to synchronously and reversely rotate. The speed reducer has the advantages of small size and large reduction ratio.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a bevel gear staggered-tooth reducer. Background technique [0002] In the reducer family, the planetary reducer is widely used for its small size, high transmission efficiency, wide deceleration range, high precision and many other advantages. However, when the transmitted power is large, it is necessary to increase the weight of each part of the reducer. Size, in order to increase the reduction ratio, this will inevitably increase the size and weight of the reducer, which cannot be installed in small equipment, and does not conform to the current development trend of equipment miniaturization. [0003] To sum up, how to reduce the volume of the planetary reducer under the condition of obtaining a large reduction ratio has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The technical problem to be solved by the present in...
