Four two dial one thousand jins of reducer is ubiquitous, but by the state monopoly high-end fine reducer

Reducer is the prime mover and work machine or actuator between matching speed and transmission torque of the role, is used widely in modern machinery. Reducer is a relatively sophisticated machinery, using its purpose is to reduce rotation speed, increase torque. 01 ▼ reducer reducer fundamental structure is mainly composed of transmission parts ( Gear or worm) , shaft, bearing, box and its accessories. Bring about the gear shaft with gear shaft of reducer transmission parts or flat key connection way of gear and shaft, bearing is splashing through the thin oil gear rotates, smooth stop. Body is the base of the transmission parts, should have sufficient strength and rigidity. Cabinet is usually made of gray cast iron, on overloading or an impact load reducer can also cast steel casing. Reducer fittings should be thought to the smooth oil pool oil for gear reducer, oil discharge, check the oil level height, processing, maintenance when assembling and disassembling of the box cover and the box of accurate positioning, loading auxiliary parts and components, such as reasonable selection and design. Working principle of gear reducer, general used for low speed high torque transmission device, the electric motor, internal combustion engine, or other high speed operating of power after a less number of teeth of gear reducer input shaft, gear on the output shaft to reach the big gear deceleration, the purpose of the ordinary there is few on the same principle of gear reducer and reach the ideal slowing effect, the size of the ratio of the number of teeth on the gears, transmission ratio. 02 classification ▼ ordinary gear reducer reducer has a helical gear reducer ( Including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc. ) , planetary gear reducer, cycloid pin wheel reducer, the worm gear and worm gear reducer, planetary reducer, etc. Bring bring helical gear reducer gear USES gleason spiral bevel gear reducer reducer hyperbolic gear type, hard tooth surface gear for, have bearing ability, low noise, long life, high efficiency and smooth operation. Bring planetary gear reducer planetary gear reducer with small volume, high transmission efficiency, speed range, high precision of many advantages, and is widely applied to the servo motor, stepper motor, dc motor drive system. Its role is on the premise of guarantee the fine transmission, mainly used to reduce speed increase torque and lower than the rotational inertia of the load/motor. Bring cycloidal pinwheel reducer cycloidal pinwheel reducer on the input shaft is equipped with a displacement of 180 ° double eccentric sleeve, turn on the eccentric sleeve is equipped with two called arm of roller bearing, a H, two cycloid gear center hole is the eccentric sleeve on the turning arm bearing raceway, and by a group of cycloid gear and pin gear mesh circular permutation needle, to form tooth difference for the internal meshing gear reducer. Bring about worm gear and worm reducer worm reducer is a kind of power convey agencies, and the gear speed converter motor ( The motor) Number of rotary rotary deceleration to want, and get a larger torque. In the current used in transmitting power and movement of institutions, the application range of the speed reducer is fairly common. Bring planetary reducer planetary reducer is a kind of universal general new reducer, internal gear are 20 CVMNT carburizing and quenching and grinding. The machine has the structure size is small, large output torque, speed ratio in safe reliable, high efficiency and performance characteristics. 03 fine reducer monopoly ▼ by Japan as the traditional manufacturing powerhouse, Germany, Italy, Japan and other countries of the reducer in the degree of information, design, quality control, product accuracy, power density and strong in the industry first position and using life, etc. Fine reducer, it is a kind of dynamic convey institutions, the application of gear speed converter, the motor of rotary rotary deceleration to want, and get the installation of large torque. Bring Nabtesco global most elaborate reducer reducer market share occupied by Japanese companies: Nabtesco accounted for about 60% of the RV reducer, Harmonica harmonic reducer accounted for about 15%. Bring about dismantling precision reducer internal structure Nabtesco precision reducer used in satellites, radar antenna, industrial robots, welding technology and semiconductor industrial automation product category of many applications.
