Problems solved by technology

Single-point and multi-point automatic grease supply devices are mainly used for regular automatic grease supply of vehicles and mechanical equipment. The grease supply is discontinuous and the grease supply speed is too low, so it is not suitable for the automatic grease supply of the test device.

Abstract

The invention discloses an automatic trace grease supply apparatus for a test. The apparatus comprises a foundation support, a servo motor, a coupler, a reducer, a ball nut screw, a guide rod, a piston, a grease bucket, a sealing ring, a screw and a nut, wherein the servo motor is fixed on the foundation support by virtue of the screw, and a motor output shaft is connected with a reducer input shaft by virtue of the coupler; an output shaft of the reducer is connected with the screw by virtue of the coupler and drives the screw to rotate at a low speed; a nut pair of the ball nut screw is connected with the piston; when the screw rotates, the nut pair is pushed to move, the nut pair drives the piston to move along the axis direction under the guiding effect of the guide rod, and lubricating grease is extruded from a grease outlet on the bottom of the grease bucket; and the grease supply speed and the grease supply amount can be adjusted by adjusting the rotation speed of the servo motor so as to meet the requirements of different test apparatuses. The automatic trace grease supply apparatus is simple in structure, convenient to operate, stable and adjustable in lubricating grease output speed and flow and free from being influenced by the external environment.

Description

technical field [0001] The invention relates to a fat supply device, in particular to a micro-volume automatic fat supply device for testing. Background technique [0002] As a lubricating medium, grease plays an important role in reducing energy consumption, reducing wear and improving equipment life. In order to understand the performance of grease, many devices for testing the performance of grease have been developed, and many experimental devices require continuous grease supply. The traditional manual fat injection method is labor-intensive and the amount of fat supplied is uneven, which has a great influence on the test results and is generally not adopted. Existing automatic grease supply devices mainly include: pneumatic grease injection pump, automatic liposuction pump, single-point and multi-point automatic grease supply devices. Among these devices, the pneumatic grease injection pump is the most widely used, but the grease output speed of the pneumatic grease ...
