Liquid sticky planetary speed regulating device

Abstract

The invention discloses a liquid viscous planetary speeder which comprises a liquid viscous speed regulating system and a planetary speed regulator; outer teeth are arranged on an outer gear sleeve of the planetary speed regulator; teeth of a gear shaft are engaged with the outer teeth of the outer gear sleeve; the gear shaft is rotatably positioned on a gear box body; an output shaft of a prime motor is directly connected with the gear shaft of the planetary speed regulator through a direct coupling shaft and a connecting shaft; a transmission wheel is arranged on the output shaft of the prime motor and is connected with a synchronizing transmission wheel of a drive shaft of a speed regulator core of the liquid viscous speed regulator through a transmission belt or a chain; a transmission wheel of an output shaft of the speed regulator core is connected with an input shaft of the planetary speed regulator through the belt or the chain; and an output shaft of the planetary speed regulator is connected with a main shaft of a loading machine. The liquid viscous planetary speeder realizes the aim of using the small-power liquid viscous speed regulator to control the large-power loading machine and has the advantages of small size, small occupied area, simple structure, low cost and reliable operation.

AI Technical Summary

Problems solved by technology

[0003] The existing liquid-viscous governor is a soft-start and speed-adjusting and torque-transmitting device, which is used in high-power fans and water pumps to achieve the purpose of speed regulation and energy saving. However, because its power needs to be the same as the load power of the speed regulation, its volume is huge. It not only occupies a large area, but also has high cost, high cost of use and maintenance

Its structure is complex and its reliability is low

The planetary governor is hard-connected to start, its structure is simple and reliable, it is convenient to use and maintain, and it has a large range of carrying capacity, but it cannot be used for energy-saving speed regulation and soft start of high-power fans and water pumps.
