Two-way manual input structure for electric cylinder

Abstract

The invention discloses a two-way manual input structure for an electric cylinder. The two-way manual input structure for the electric cylinder comprises a transfer plate, a gear, a gear case, an upper bearing pressing plate, a lower bearing pressing plate, an upper bearing, a lower bearing, a cover plate, a pressing plate, a manual input shaft, a large bevel gear, a small bevel gear, an adjusting backup ring, a bearing sleeve and a manual shell. The two-way manual input structure is added at the rear portion of the gear case through an output shaft of a reducer or a motor and the connecting gear, the purpose of integrating a manual function in a small space is achieved, and the manual structure has an input-direction choosing function; the structure achieves the manual function by fully utilizing a rear support lug side space size of the foldback type electric cylinder, the manual input shaft of the structure is coaxial with an electric cylinder rear hinged shaft, and thus the manual function is easy to achieve; the structure has the characteristics of being compact in structure and low in weight, and the axial length of the electric cylinder is not added; and the two-way manual input structure for the electric cylinder has a watertight structure and meets the requirements for environment of outdoor use.

Description

technical field [0001] The invention belongs to the technical field of transmission systems, and mainly relates to a bidirectional manual input structure for an electric cylinder. Background technique [0002] Electric cylinder is a kind of mechanical execution structure with motor as energy. It has the characteristics of easy control, no pollution, high reliability, low maintenance cost and few accessories. It is one of the ideal linear actuators to replace hydraulic system in the future. The main power source of the electric cylinder is the motor. Relying on the power supply, the motor and the control system, once the power source fails, how to complete the emergency function or maintenance operation must be considered. Therefore, many electric cylinder products require manual functions. At present, the manual driving methods of electric cylinders mainly include the following: one is to customize the motor, leaving a manual input interface at the end of the motor, and usin...
