Abstract

The invention discloses a coaxial input transmission device. The coaxial input transmission device comprises a base, an outer cylinder, an inner cylinder, a rotary knob, an output shaft, a rotary table bearing, a bevel gear wheel, an upper locking sleeve, an upper locking sheet, a lower locking sleeve, a lower locking sheet, an upper spring and a lower spring; the upper locking sleeve, the lower locking sleeve and the base form a moving pair, and one spring is arranged between the upper locking sleeve and the base as well as the lower locking sleeve and the base; the rotary knob and the upperlocking sleeve form a revolute pair; the inner cylinder and the lower locking sleeve form a revolute pair; anti-skid teeth I which can mesh with each other are arranged at the center of the bevel gearwheel and the lower end of the rotary knob separately; anti-skid teeth II which can mesh with each other are arranged at the lower end of the inner cylinder and the lower end of the inner side of theouter cylinder separately; the upper locking sleeve can lock the rotation of the output shaft; the lower locking sleeve can lock the rotation of an output arm; a hand wheel can control the output armto rotate; when the hand wheel does not rotate, the output arm is locked, and the rotary knob can control the output shaft to rotate; and when the rotary knob does not rotate, the output shaft is locked.

Description

technical field [0001] The invention relates to a transmission device, in particular to a coaxial input transmission device. Background technique [0002] In some existing transmission devices, the positioning locking structure is usually a separate device. When power input is required, the locking device needs to be unlocked. After the power input is stopped, the locking device needs to be restarted. Such a structure is inconvenient to operate. The locking device wears a lot and affects the timeliness of the transmission. [0003] Chinese patent document CN201410472765.5, published on December 31, 2014, discloses a brake positioning device for a power-assisted mechanical arm, which includes a fixed connection seat and a rotating arm mounted on the fixed connection seat through a drive spindle. When the brake is required to position and stop, The single-acting cylinder is fed with compressed air, and the single-acting cylinder pushes the brake disc to move downward and enga...
