Application characteristics of gear-type rotary cylinder, working principle of gear-type rotary cylinder structure

Gear-type rotary cylinder application

Mainly used in underground operations, chemical industry, metallurgical industry and heavy industry, used to drive power conveying equipment, winches, etc.;used to drive pumps and safety devices, converters, mixers, etc. The driving of charging equipment, oxygen blowing guns, turrets and other types of furnaces and the start-up of diesel enginesRotating cylinderetc.

Features of gear-type rotating cylinder

①Simple structure, reliable operation, low requirements on air source quality, impact resistance and low inertia;

②The output power per unit weight is high and the overall volume is small;

③The torque pulsation is large, the air consumption is large, and the efficiency is low;

④The output power can reach about 70kW, the output power of the herringbone rotary cylinder can even be about 330kW, and the speed is as low as 1000~3000r/min.

Gear-type rotating cylinder structurePrinciple

The working chamber of this rotating cylinder is composed of a pair of gears. Compressed air is input from the center of symmetry, and the gears rotate under the action of pressure. The rotary cylinder using spur gears can rotate forward and reverse, but the rotary cylinder using herringbone gears or helical gears cannot rotate reversely.

If a spur gear rotating cylinder is used, the supplied compressed air will not expand when passing through the gear, so the efficiency is low. When using herringbone gears or helical gears, the compressed air expands by 60% to 70%, improving efficiency.

Working principle of gear-type rotating cylinder

In the gear-type rotating cylinder, compressed air acts on the tooth flanks of the two gears. Among the gears, one is fixed on the working shaft, and the other is meshed with it. The force to rotate it is the product of the pressure and the tooth side area.

Gear-type rotating cylinders include double-gear type and multi-gear type, and the double-gear type is the most widely used. Its structural forms include: spur gear rotating cylinder;helical gear rotating cylinder;herringbone gear rotating cylinder.

Spur gear rotating cylinder is a machine that works entirely on the static pressure of the filled medium. Compressed air does not expand during the entire working process, that is, its expansion work is not utilized. Helical gear and herringbone gear rotating cylinder are two forms of rotationThe cylinder utilizes part of the expansion work of the compressed air during its working process.
