Embodiment Construction
[0021] The present invention will be further described in detail below, which is an explanation of the present invention rather than a limitation. The present invention will be further described below in conjunction with the accompanying drawings.
[0022] According to the characteristics of the planetary gear reducer, when the inner gear is fixed, turning the sun gear can drive the planetary gear to drive the planet carrier to rotate and output; when the sun gear is fixed, turning the inner gear can also drive the planet gear to drive the planet carrier to rotate and output. The outer casing of the inner gear of the planetary gear reducer is made into a worm gear, and connected with the worm to form a worm reducer. Due to the self-locking performance of the worm, the worm gear can only be driven to rotate when the worm rotates, and the worm wheel cannot rotate when the worm does not move, that is, the internal gear cannot rotate either.
[0023] According to the above charac...

The invention provides a dual-input integration speed reducer. The dual-input integration speed reducer comprises a driving wheel, a transmission mechanism, a linkage part and a driving part, whereinthe driving wheel is connected with an input shaft, the transmission mechanism is connected with the driving wheel and an output shaft, the linkage part is arranged on the outer side of the transmission mechanism, and the driving part is connected with the transmission mechanism through the linkage part. The linkage part is a worm gear, the driving part is a worm, and the driving part is engaged with the linkage part. The inner edge of the linkage part is provided with internal teeth. The transmission mechanism comprises a plurality of planet gears and a planet carrier, wherein the planet gears are engaged with the driving wheel and the linkage part; and the planet carrier is arranged on the planet gears and connected with the output shaft. The multiple planet gears are connected through the planet carrier. The driving wheel is a sun gear. Compared with the prior art, the dual-input integration speed reducer has the following beneficial effects that switching of electric driving and manual driving of a transmission device can be conveniently achieved; the transmission device is compact in structure and light; and a connecting rod and a universal spindle coupling are used so that remote arrangement of the manual operating position can be achieved.
Description
technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a dual-input integrated reducer. Background technique [0002] The reducer is a mechanical device that is widely used in mechanical transmission. It is usually installed in the transmission link to reduce the speed and increase the torque. When designing some mechanical transmissions, it is necessary to consider setting up the electric drive link and the manual drive link at the same time (under working conditions, the motor or other device drives the device through the electric drive link, and in the case of maintenance and inspection, etc. Human power is driven by manual drive link drive device), and convenient switching between the two can be achieved. Usually, when designing this aspect, measures to increase the clutch are taken, such as figure 1 As shown, it includes a planetary gear reducer 1, a motor input shaft 2, a manual input shaft 3, a clutch gear 4 ...
