Abstract
The invention relates to a gear reduction unit, and relates to the technical field of machines. The gear reduction unit comprises a gear seat, a cylindrical inner gear, sun wheels and a rear cover. The sun wheels comprise the first sun wheel and the second sun wheel. Three first straight gears are arranged at the rear end of the first sun wheel. Three second straight gears are arranged on the rear face of the second sun wheel. A pinion is arranged on the front face of the second sun wheel. The pinion is meshed with the three first straight gears. The cylindrical inner gear is arranged in the gear seat. The sun wheels are arranged in the cylindrical inner gear. The second straight gear is meshed with teeth of the cylindrical inner gear. The rear cover covers the gear seat. The gear reduction unit can be applied to different deceleration systems, conducts double reduction, and is good in reduction effect, and high in practicability.
Description
Technical field
The invention belongs to field of mechanical technique, particularly relate to a kind of gear reducer.
Background technique
Speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtains the mechanism of larger torque.Current in the mechanism of transferring power and motion, the application area of speed reducer is quite extensive.Its trace almost can be seen in the transmission system of various machinery, from boats and ships, automobile, the locomotive of the traffic tool, heavy machinery for building, the machining machine and tool that mechanical industry is used and automated production equipment, household electrical appliances common in daily life, clock and watch etc.Its application is from the transmission work of large power, and to Smaller load, accurate angle transmission can see the application of speed reducer, and in commercial Application, speed reducer has deceleration and increases torque functions.Therefore the conversion equipment of speed and moment of torsion is widely used in.
Speed reducer is a kind of relatively accurate machinery, uses its object to be reduce rotating speed, increases torque.It of a great variety, model is different, and variety classes has different purposes.Retarder of a great variety, can be divided into gear reducer, worm reducer and plane table thermoconductivity meter according to actuation types; Single-stage and multi-stage speed reducer can be divided into according to transmission progression difference; Cylinder gear speed reducer, cone gear reducer and circular cone one cylinder gear speed reducer can be divided into according to gear shape; Expansion, flow deviding type and coaxial-type retarder can be divided into again according to the setting type of transmission.The present invention accordingly provides a kind of gear reducer, carries out double reduction, and slowing effect is good, and applicability is strong.
Summary of the invention
For meeting above-mentioned technical requirements, the object of the invention is to provide a kind of gear reducer.
The solution of the present invention is as follows:
A kind of gear reducer, comprises pinion stand, cylindrical internal gear, sun gear and bonnet; Described sun gear comprises sun gear one and sun gear two, and sun gear one rear end is provided with three spur gears one; Sun gear two is below provided with three spur gears two, before be provided with a small gear; Small gear and three spur gears one engage; Be provided with cylindrical internal gear in described pinion stand, sun gear is arranged in cylindrical internal gear, the tooth engagement of spur gear two and cylindrical internal gear; Described bonnet covers on pinion stand.
