Abstract

The utility model provides a lightweight structure of an electric cylinder, and relates to the technical field of application of electric cylinders. The output torque of the motor is transmitted to the screw shaft through the gear pair to drive the screw to rotate so as to drive the screw nut to do linear motion, and the flange plate welded on the push rod is acted by the screw nut to drive the load to do linear motion along the guide post. Through the guide post with the guiding function, the utility model can reduce the weight of the electric cylinder under the condition that the cylinder barrel of the electric cylinder is not stressed or is stressed little by matching with the mode that the organ cover with the protecting function replaces the cylinder barrel of the electric cylinder under the condition that the cylinder barrel is not stressed or is stressed little, thereby saving the cost and improving the competitiveness.

Description

Structure of electronic jar lightweight

Technical Field

The utility model provides a lightweight structure of an electric cylinder, and relates to the technical field of application of electric cylinders.

Background

The electric cylinder is widely applied to power equipment in the fields of engineering machinery, military equipment, automation and the like. The traditional electric cylinder structure generally adopts metal materials such as cast iron or steel as a cylinder barrel shell, and the weight of the structure is large and the energy efficiency is low. With the development of the trends of light weight, high efficiency, energy saving and the like, the light weight requirement of the electric cylinder is more and more urgent. Therefore, the utility model provides a novel lightweight structural design of the electric cylinder, and the weight of the electric cylinder is reduced under the condition that the cylinder barrel of the electric cylinder is not stressed or is stressed little, so that the cost is saved, and the competitiveness is improved.

Disclosure of Invention

The utility model aims to provide a lightweight structure of an electric cylinder, which aims to solve the problem that the electric cylinder in the background art has large weight.

In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a structure of electronic jar lightweight, includes motor reducer subassembly, cylindrical gear pair, lead screw subassembly, gear box body, gear box lid, bearing frame subassembly, ring flange, guide post, organ cover.

The input end of the speed reducer is connected with the output end of the motor, the output end of the speed reducer is connected with the input end flange of the gear box body, the cylindrical gear pair is arranged inside the gear box, the cylindrical driven gear is connected with the input end of the lead screw, the lead screw is connected with the push rod, the flange plate is welded with the push rod, the bearing seat is connected with the gear box body, and the guide post penetrates through the through hole of the flange plate and is fixed on the bearing seat.

The flange plate is welded on the push rod and moves linearly along the guide post fixed on the bearing seat with the push rod under the action of the screw nut. The guide key is arranged on the outer wall of the push rod in the traditional design, and the guide key and the cylinder barrel key groove are matched, so that the guide effect of the cylinder barrel is replaced.

One end of the organ cover is fixed on the bearing seat, and the other end of the organ cover is connected with the lower end of the flange plate and contracts or stretches along with the up-and-down movement of the flange plate. The organ cover stretches along with the extension of the electric cylinder, can prevent water and dust, and plays a role in protecting the screw rod assembly.

The design of no electronic jar cylinder, when load and electronic jar adoption side flange joint, cylinder atress or atress in the traditional design is little, and the atress is mainly concentrated on the lead screw, and the cylinder weight is great but only provides the effect of direction and protection, through the effectual weight that reduces this part of the design of guide post and organ cover.
