Reducer introduction:

Reducer in the prime mover and working machine or actuator between the matching speed and torque transmission, reducer is a relatively sophisticated machinery, the purpose is to reduce speed, increase torque.

According to the transmission series, it can be divided into single-stage and multi-stage reducer; according to the gear wheel shape of the gear mill, it can be divided into cylindrical gear reducer, bevel gear reducer and cone cylinder gear reducer;According to the layout of transmission, it can be divided into expansion type, split flow type and the same shaft type reducer.The reducer is a kind of independent parts enclosed by a rigid shell gear, worm gear, gear - worm gear reducer, commonly used as a prime mover and work machine.The matching speed and torque transmission between the prime mover and the working machine or the actuator are widely used in modern machinery.

RV reducer worm reducer

RV reducer worm reducer is one of Shanghai a special reducer factory production, which is composed of worm and worm wheel, has the advantages of compact structure, large transmission ratio, and has the self-locking function under certain conditions, the mechanical drive, speed reducer is one of the most commonly used and small vibration, low noise, low energy consumption.

NMRV series reducer is suitable for food, leather, textile, glass, ceramics, medical, chemical, light industry and other machinery and equipment, especially suitable for all kinds of automatic transmission reducer.

Performance characteristics:

Worm fly rod drive the vertical output, compact structure, high precision and good work smoothly with low noise and long service life. The installation: foot mounting, hollow shaft, flange installation, torque arm installation, small flange installation. Input mode: motor direct electrical connection or a belt input shaft flange type connection. The output mode: hollow or solid shaft output shaft output, the average rate is 80%. The double combination can have greater speed ratio.

Technical parameters:

speed ratio range: basic type 5~5500, more than three combinations can reach 32625 torque range: 2~300 Nm power range: 0.045 ~ 22kW

2.type:

The input type of aluminum alloy reducer is divided into four types: hole input, shaft input, shaft input with extension, and flange input with extension. The output form is divided into four types: hole output, one-way shaft output, bidirectional shaft output and flange output. F... (1 - 2) with output flange. VS with the same direction input shaft. AS with one way output shaft. AB with two way output shaft.

Note: with the output flange basic price plus 10% yuan, one-way output shaft basic price plus 10% yuan, AZ two-way output shaft plus 10% yuan, torque arm 11% yuan.

The speed ratio of the 3. reducer is 7.5, 10, 15, 20, 25, 30, 40, 50, 60, 80,100
