Problems solved by technology

However, if the structure of the traditional rotary planetary gear reducer is used, an intermediate conversion device needs to be added when driving the corresponding equipment to move linearly, which increases the cost investment and has certain limitations. Therefore, a planet that can realize high-speed and stable linear reciprocating motion is urgently needed. wheel reducer

Abstract

The invention belongs to the technical field of mechanical reducers, and relates to a planetary gear reducer whose output shaft can reciprocate in a straight line and its application. The upper casing and the lower casing are fixedly connected, the frame is fixedly connected to the lower casing, an input shaft is installed on the upper casing, a gear is arranged on the input shaft, and the gears are meshed and connected There is a gear drum, and mounting holes are arranged on the upper and lower parts of the gear drum, and the axis of the mounting hole is parallel to the axis of the gear drum, and a planetary shaft is arranged in the two mounting holes, and the planetary shaft is arranged in the two mounting holes. The middle key is connected with a planetary gear, the planetary gear is meshed with an internal gear, the internal gear is fixed on the frame, and the upper end of the planetary shaft passes through the No. 2 end cover and is provided with a connecting block, on the upper part of the connecting block The surface is eccentrically provided with an output shaft. The planetary gear reducer of the invention has compact structure, low manufacturing cost, high transmission efficiency, shortens the transmission chain, improves efficiency, and meets the requirements of linear reciprocating motion in different application scenarios.

Description

technical field [0001] The invention belongs to the technical field of mechanical reducers, and relates to a planetary gear reducer whose output shaft can reciprocate in a straight line. Background technique [0002] Planetary gear reducers are widely used in metallurgical machinery, engineering machinery, chemical machinery, textile machinery and other transmission systems due to their small size, high transmission efficiency, wide deceleration range, and high precision. Under the premise, it is mainly used to reduce the rotational speed, increase the torque and reduce the load / motor inertia moment ratio, so as to realize the rotary motion of the corresponding mechanical part. The main transmission structure of planetary gear reducer is composed of planetary gear, sun gear, ring gear and planet carrier. With the rapid development of the national economy, the application of planetary gear reducers has become more and more extensive, and more requirements have been placed on...
