Abstract

The invention discloses an electric cylinder with a circulation cooling channel, and belongs to the field of driving machines. The electric cylinder comprises a machine case, a motor, a lead screw, alead screw nut which are mounted in the machine case, and a front end cover and a rear end cover which are used for sealing the two ends of the machine case. The electric cylinder further comprises acooling mechanism, wherein the cooling mechanism is provided with a lubricating oil circulation channel; the lubricating oil circulation channel comprises a first oil storage area formed by the frontend cover and the gap between the machine case and the motor, a second oil storage area formed in the machine case, and a third oil storage area formed by the rear end cover and the gap between the machine case and the motor, wherein the first oil storage area is communicated with the second oil storage area, and the second oil storage area is communicated with the third oil storage area. The cooling mechanism is utilized to transfer the heat in the electric cylinder out of the machine case through circulation flowing in the lubricating oil circulation channel, the double effects of cooling and lubricating of the electric cylinder are achieved, thermal abrasion is reduced, the stability of the electric cylinder is improved, and the service life of the electric cylinder is prolonged.

Description

technical field [0001] The invention belongs to the field of transmission machinery, and in particular relates to an electric cylinder with a circulating cooling channel. Background technique [0002] The electric cylinder is a device that converts the rotary motion of the servo motor into the linear motion of the piston rod, and drives the electric cylinder screw to expand and contract to generate tension. Electric cylinders have high motion precision, fast response, and good rigidity, and have replaced servo hydraulic cylinders in many fields. During the operation of the traditional electric cylinder, the cooling water directly cools the cavity of the machine body, and takes away the surface heat of the machine body, so as to reduce the frictional heat during operation. Such a cooling method cannot be cooled by circulating flow, and the electric cylinder rotates positively and negatively and reciprocates axially for a long time, resulting in high frictional heat of the pa...
