AI Technical Summary

Technical Problem

Existing cooling devices for geared pneumatic motors are energy-intensive and complex in structure, making it difficult to effectively cool the reduction gear and braking device.

Method used

An air-cooled device is used, with a cooling pipeline connected to the buffer tank via the pneumatic motor exhaust pipe. A control valve controls the opening and closing of the cooling pipeline. A cooler located at the bottom of the gearbox provides jet oil cooling, which is combined with the brake cooling pipeline to provide jet cooling for the brake device. A pressure exhaust valve is installed on the buffer tank to prevent air blockage.

Benefits of technology

It achieves a simple structure and significant cooling effect, improving the working efficiency and cooling effect of the pneumatic motor and reducing energy consumption.

Abstract

The utility model discloses a kind of air cooling device of deceleration type pneumatic motor, including pneumatic motor, buffer tank, reduction gearbox, brake device, brake cooling pipeline and reducer cooling pipeline. The exhaust pipe of pneumatic motor is communicated with buffer tank, and control valve is arranged on the cooling pipe of buffer tank;Control valve controls brake cooling pipeline to spray gas cooling work to brake device. The cooler of reducer cooling pipeline passes through cooling lubricating oil at the bottom of deceleration, and takes away the heat in the inside of reduction gearbox. Or cooler carries out jet oil injection cooling work, and moves component inside reduction gearbox is lubricated by jet oil injection. The utility model is circulated cooling or gas injection cooling work by the pressure air discharged by pneumatic motor, and structure is simple, cooling efficiency is high.
