AI Technical Summary

Technical Problem

In existing technologies, when bidirectional lubricating oil needs to be transported, two independent gear oil pumps and drive components are required, which increases the system construction cost and energy consumption.

Method used

The system employs a dual-rotation, bidirectional gear oil pump. A single drive motor drives a bevel gear, which in turn drives two transmission bevel gears, enabling bidirectional delivery of lubricating oil. A stable mechanical support system is constructed using a mounting bracket and a positioning ring, ensuring stable meshing accuracy of the transmission system under high load conditions.

Benefits of technology

It enables bidirectional delivery of lubricating oil, reduces equipment costs, maintains the stability and reliability of the transmission system under high load conditions, and extends service life.

Abstract

This utility model discloses a dual-rotation, bidirectional gear oil pump, relating to the field of oil pump technology. It includes a dual-rotation drive assembly and a bidirectional gear oil pump assembly. The bidirectional gear oil pump assembly includes a mounting base plate and two lubricating oil delivery chambers, with a transmission cylinder fixedly connected between the two lubricating oil delivery chambers. The dual-rotation drive assembly includes a drive bevel gear, two transmission bevel gears, and a mounting bracket. One end of the drive bevel gear meshes with the other ends of the two transmission bevel gears. A first drive shaft is fixedly connected inside one transmission bevel gear, and a second drive shaft is fixedly connected inside the other transmission bevel gear. This utility model uses a drive motor to drive the drive bevel gear to rotate, causing the oil delivery gears in the two lubricating oil delivery chambers to rotate in opposite directions, achieving bidirectional lubricating oil delivery. Furthermore, only a single drive motor is needed to drive both lubricating oil delivery chambers, reducing equipment costs.
