Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] According to the performance parameters of the KSB type motor and the large-scale boiler water supply pump, the transmission scheme of the speed-regulating hydraulic coupling is determined as the compound gear speed-up before the speed-up and the speed-up after the speed-up. The rated power transmitted by the invention is 12000kw, the rated input speed is 3000r / min, and the rated output speed is 10000r / min. The purpose of this transmission scheme is to improve the input speed and transmission power capacity of the hydraulic coupling, while reducing the specification of the coupling and meeting the requirements of the input speed of the boiler water pump.

[0020] Determine the original design parameters of the hydraulic coupling based on the performance parameters of the KSB type motor and the large boiler water supply pump: rated transm...

Abstract

The utility model relates to a speed-regulating hydraulic coupler transmission device of a large-power compound gear capable of speeding up front and rear. The device consists of a hydraulic coupler, a front speed-up herringbone gear, a rear speed-up herringbone gear and an oil line system; the hydraulic coupler adopts a speed regulation mode of adjusting a telescopic conduit at an outlet; the front part and the rear part of the hydraulic coupler are provided with a primary herringbone gear speed-up transmission mechanism respectively; the input rotating speed and capability for transmitting power of the hydraulic coupler are improved by the front speed-up gear transmission, thus reducing the specification of the coupler; the oil line system comprises a working oil pump, a main lubricating oil pump and an auxiliary lubricating oil pump that are gear oil pumps. The device leads a motor and a working machine to match well, improves the transmission quality, improves the running efficiency of the working machine, leads a water supply pump of a boiler to work at a high-efficiency area all the time, greatly improves the working efficiency of the water supply pump of the boiler by the hydraulic speed regulation, saves a large amount of electric energy, and greatly reduces the consumption of energy resource.

Description

technical field [0001] The invention relates to a high-power composite gear speed-increasing front speed-up rear speed-regulating type hydraulic coupling transmission device applied to large-scale boiler feed water pump mechanical equipment. Background technique [0002] A fluid coupling transmission is a combination of a fluid coupling and a gear transmission element. The speed-regulating hydraulic coupling transmission device can realize stepless adjustment of the output speed under the condition that the motor speed is constant. It can improve the starting ability of the motor, reduce shock and vibration, and coordinate the load distribution of multi-machine drives. It is also easy to Realize remote control and automatic control and can save a lot of electric energy. It has no limit on the voltage of the motor, and can adapt to high voltage, high power, and high speed conditions. It is currently widely used in various mechanical equipment such as fans, water pumps, and m...
