Dual-speed planet speed reducer

Abstract

The invention relates to a planetary double-speed reducer. It is characterized in that it includes a box body and a planetary transmission gear set. The planetary transmission gear set includes an input gear that meshes with the sun gear and is a sliding gear that can slide along the input shaft. A shift fork is provided on the outer circumference of the sliding gear near the input end. groove; the inner circumference of the other end is provided with internal teeth capable of engaging with the sun gear, and the outer circumference is provided with external teeth capable of engaging with a fixed gear sleeve, which is fixedly connected to the planet carrier of the planetary transmission gear set, The shift fork slot on the outer circumference of the sliding gear is connected to the shift fork mechanism, and the shift fork mechanism is installed on the box body. The invention has large bearing capacity, small size, reliable operation, and realizes coaxial double-speed output, and is suitable for various fields such as mine hoists, mines, metallurgy, cement, building materials, energy, light industry, chemical industry, marine, and bridging machinery.

Description

technical field [0001] The invention relates to a reducer, in particular to a planetary double-speed reducer. Background technique [0002] At present, in many industries, especially the hoisting and hoisting industries, in order to improve work efficiency, the lifting speed needs to be slow when lifting heavy loads, and the speed needs to be fast when lifting no load. The existing speed regulation means mainly There are motor speed regulation and clutch (electromagnetic clutch and hydraulic clutch) speed regulation, but the speed ratio of motor speed regulation is limited, generally not more than 2; the electromagnetic clutch transmits small torque, and the speed ratio change is small; the cost of hydraulic clutch is high. The planetary reducer is usually a single speed output, which cannot meet the requirements of speed regulation. Contents of the invention [0003] The present invention provides a planetary double-speed reducer with large transmission torque and capabl...

[0002] At present, in many industries, especially the hoisting and hoisting industries, in order to improve work efficiency, the lifting speed needs to be slow when lifting with heavy loads, and the speed should be fast when lifting with no load. The existing speed regulation means mainly There are motor speed regulation and clutch (electromagnetic clutch and hydraulic clutch) speed regulation, but the speed ratio of motor speed regulation is limited, generally not more than 2; the electromagnetic clutch transmits small torque, and the speed ratio change is small; the cost of hydraulic clutch is high

The planetary reducer is usually a single speed output, which cannot meet the requirements of speed regulation.
