Full Automatic Speed Increasing Gear Box for Finishing Mill Equipment

Velocity rising equipment box of 135m ending mill

Composition of pace growing gearbox
Spare areas of velocity increasing gearbox case(decrease circumstance, middle situation and go over), assist foundation, huge equipment, transmission axis, bevel wheel and lubrication program.

Complex characteristics
Box is soften with thick metal with great good quality to reach the intensity that the scenario essential. Circumstance must take stress growing older treatment just before the make to attain the balance that needed. High precision lathe machining is employed for the assembly of circumstances to insure the locating accuracy of each and every bearing holes and related joint floor.

Huge gears and equipment shaft used carbon alloy steel forging blank, following roughing, workpiece require to consider ultrasonic flaw detection method to quench. In purchase to guarantee the tooth surface with higher hardness, tooth area want to consider carburizing and quenching therapy right after semi-finishing. Wonderful grind of tooth surface to insure the high precision, following ending the production of gear, the equilibrium take a look at is required, the trail speed is 1500r/min and the equilibrium precision quality is G2.5. The path speed of bevel wheel is 3500r/min, the harmony precision quality is G1, in so to ensure the rotary precision of the gears.

Transmission shaft use the alloy metal forging blank, transmission shaft requires quenched to make positive the intensity and durableness. After the semi- finishing, transmission need to grind to promise the precision of each and every workpiece.
When the assemble finished, the no-loading take a look at must be keep 2-4hours, the velocity is 1100r/min, the temperature of shaft should not exceed 40º C, the work of equipment must be smooth, no hitting sound and concussion, each and every joint floor must not have oil spill phenomenon.
