AI Technical Summary

Problems solved by technology

There are also very few that use an additional pumping station outside the mechanism itself for forced lubrication, but the structure is relatively loose, requiring additional oil pumps and motors (or additional transmission-driven oil pumps)
In some special applications, the speed reducer is required to have a compact structure, large transmission power (above 5.5KW), high speed (above 190,000RPM of the high-speed shaft), and forced oil supply is required for circulating lubrication and cooling. Traditional split lubrication Oil system or grease lubrication is not applicable

Abstract

The invention discloses a friction speed increaser for high speed transmission. The friction speed increaser comprises a speed increasing mechanism connected with a motor, and is characterized in that: a vane pump is coaxially arranged on a sun wheel shaft of the speed increasing mechanism, and is externally connected with a lubricating oil tank provided with a radiating structure. The friction speed increaser has a compact structure, and is forcibly lubricated and circularly cooled by lubricating oil, so that high lubrication and temperature rise of the speed increaser are guaranteed, and the lubricating oil is prevented from leaking.

Description

technical field [0001] The invention relates to the technical field of speed increasers, in particular to a transmission mechanism used in mechanical transmission that requires a high gear ratio, high linear velocity or angular velocity. Background technique [0002] The friction planetary speed reducer relies on the friction force between the parts to transmit torque power and change the angular velocity of the driven part. During the movement, the heat generated by deformation and friction on the contact surface of the parts will cause the temperature to rise and even the sintering of the contact surface material. Therefore, there must be good lubrication in the structure to form an oil film on the contact surface, while ensuring good heat dissipation to ensure good heat dissipation. Avoid damage to parts and oil film. The traditional friction speed increaser is mostly lubricated by grease or oil because of its low operating speed and low temperature rise of the parts, or...
