Opposite-side double-output-shaft large-transmission-ratio speed reducer with self-locking function

Abstract

The invention provides an opposite-side double-output-shaft large-transmission-ratio speed reducer with a self-locking function and belongs to the technical field of mechanical transmission. The speed reducer comprises an input shaft, a multifunctional disc, left steel balls, right steel balls, a left movable tooth carrier, a right movable tooth carrier, a left output disc, a right output disc, a left output shaft, a right output shaft and a machine frame. Movement is transmitted between the input shaft and the multifunctional disc through tooth profile engagement. The machine frame is composed of a left machine frame body and a right machine frame body. The left movable tooth carrier and the right movable tooth carrier are fixedly connected to the left machine frame body and the right machine frame body correspondingly. The left steel balls are uniformly distributed in a radial groove which is distributed in the circumferential direction of the left movable tooth carrier and located in the staggered area between a tooth profile groove in the left end face of the multifunctional disc and the left output disc all the time. Similarly, the right steel balls are uniformly distributed in a radial groove which is distributed in the circumferential direction of the right movable tooth carrier and located in the staggered area between a tooth profile groove in the right end face of the multifunctional disc and the right output disc all the time. The left output disc and the right output disc are fixedly connected with the left output shaft and the right output shaft correspondingly. By the adoption of the speed reducer, single-shaft input and opposite-side double-shaft reduction output can be achieved, the rotation directions and reduction ratios of single-shaft input and opposite-side double-shaft reduction output are identical or different, and the speed reducer has the characteristics that the structure is compact, self-locking can be achieved, and the transmission ratio range is wide.

Description

technical field [0001] The patent of the present invention relates to a self-locking double output shaft large transmission ratio reducer, which belongs to the technical field of mechanical transmission. Background technique [0002] At present, the reduction gears that have been widely used in production are mostly single-input and single-output structures, and the range of transmission ratio is relatively small, which cannot well adapt to the development of modern industry. Therefore, in order to meet the needs of industrial production for reducers, a single-input, opposite-side double-output reducer with small size, compact structure, strong bearing capacity, wide range of reduction ratios, high transmission precision, and self-locking is designed. Contents of the invention [0003] The patent of the invention realizes the uniform speed input of one input shaft, and the simultaneous deceleration output of the two shafts on the opposite side. [0004] A self-locking lar...
