Four two dial one thousand jins of reducer is ubiquitous, but high precision gear reducer is the state monopoly - bearing knowledge

Between gear reducer is the prime mover and work machine or actuator has a function in matching speed and transfer torque is widely applied in modern machinery. Reducer is a relatively sophisticated machinery, the use of its purpose is to reduce rotation speed, increase torque. Basic structure ▼ 01 reducer reducer 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 the use of gear rotates splashing through the thin oil and lubrication. Body is the base of the transmission parts, should have sufficient strength and rigidity. Cabinet is usually made of gray cast iron, for overloading or an impact load reducer can also cast steel casing. Reducer attachments should be considered as reducer oil lubricating oil pool, oil discharge, check the oil level height, processing, maintenance when assembling and disassembling of the box cover and the box accurate positioning, loading auxiliary parts and components, such as reasonable selection and design. The working principle of gear reducer: generally used for low speed high torque transmission device, the electric motor, internal combustion engine, or other high speed operating of power by less teeth of gear reducer input shaft, gear wheel on the output shaft to achieve the purpose of deceleration, ordinary reducer also can have a few on the same principle gears to achieve the ideal effect, the ratio of the size of the number of teeth on the gear, the transmission ratio. 02 classification ▼ general 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, has a large carrying capacity, low noise, long service life, high efficiency, stable operation, etc. Bring planetary gear reducer planetary gear reducer with small volume, high transmission efficiency, speed range, high precision of many advantages, is widely applied to the servo motor, stepper motor, dc motor drive system. Its role is on the premise of guarantee precision 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, the formation of 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 dynamic convey institutions, using gear speed converter, motor ( The motor) Number of rotary rotary deceleration to want, and get a larger torque. In the present that is used to transfer power and motion speed reducer application scope is quite wide. Bring planetary reducer planetary reducer is a kind of new reducer, with a broad range of general internal gear are 20 CVMNT carburizing and quenching and grinding. The machine has a structure of small size, large output torque, speed ratio in, high efficiency, safe and reliable performance, etc. 03 precision reducer monopoly ▼ by Japan as the traditional manufacturing powerhouse, Germany, Italy, Japan and other countries of the speed reducer product in material, design, quality control, accuracy, power density, is the industry leader in reliability and service life, etc. Precision reducer, it is a kind of dynamic convey institutions, the use of gear speed converter, the motor of rotary rotary deceleration to want, and get a bigger torque device. Bring Nabtesco reducer global market share of the vast majority of precision reducer is occupied by a Japanese companies: Nabtesco accounted for about 60% of the RV reducer, Harmonica harmonic reducer accounted for about 15%. Bring about dismantling the internal structure of precision gear reducer Nabtesco precision reducer has been spread all over satellite, radar antenna, industrial robots, semiconductor and welding technology of numerous applications in the field of industrial automation products.
