Speed adjusting type hydraulic synchronizator

Abstract

The invention belongs to the technical field of hydraulic transmission and relates to a speed-adjusting hydraulic synchronizer used for solving the speed adjusting of fans and water pumps with large power in particular. The invention is characterized in that one side of an end cover is provided with a shell cover; a shell is provided with the end cover and a bearing seat; a canal penetrates the bearing seat by the other end of the shell of the canal and extends into a boundary cavity formed by the end cover and the shell cover; the canal can move along the shell cavity of the canal; speed adjusting and clutching can be realized by adjusting the position of the canal in the boundary cavity. The speed-adjusting hydraulic synchronizer has the advantages of energy saving, large density of a transferring power, easy operation and control, low cost, and the like. The speed-adjusting hydraulic synchronizer is suitable for fans and water pumps with large power.

Description

Technical field: [0001] The invention belongs to the technical field of hydraulic transmission, in particular to a speed-regulating hydraulic synchronizer for speed regulation of high-power fans, water pumps and the like. Background technique: [0002] As we all know, the existing methods for solving the problem of speed regulation and energy saving of high-power fans, water pumps, etc. mainly include: speed-regulating hydraulic coupling and viscous clutch. In order to achieve the purpose of adjusting the output speed, the speed-regulating hydraulic coupling has the following disadvantages: 1. The speed-regulating hydraulic coupling has a 3-5% slip in the rated working condition of the transmission, that is, There is a power loss; 2. The transmission of the speed-regulating fluid coupling needs an additional oil supply system, which will increase the power loss; 3. The transmission capacity of the speed-regulating fluid coupling drops sharply at low speeds, which will make t...

[0002] As we all know, the existing methods for solving the problem of speed regulation and energy saving of high-power fans, water pumps, etc. mainly include: speed-regulating hydraulic coupling and viscous clutch. In order to achieve the purpose of adjusting the output speed, the speed-regulating hydraulic coupling has the following disadvantages: 1. The speed-regulating hydraulic coupling has a 3-5% slip in the rated working condition of the transmission, that is, There is a power loss; 2. The transmission of the speed-regulating fluid coupling needs an additional oil supply system, which will increase the power loss; 3. The transmission capacity of the speed-regulating fluid coupling drops sharply at low speeds, which will make the low-speed When the coupling is bulky, the fluid viscous clutch achieves the purpose of adjusting the output speed by adjusting the thickness of the oil film between the friction plates. The fluid viscous clutch has the following disadvantages when used for speed regulation: 1. It needs another oil supply system, which will have power Loss; 2. Complicated control system; 3. Higher requirements on oil quality, which will increase the cost of use; 4. Higher requirements on processing technology, otherwise it will be difficult to meet the design requirements and the production cost will be high

[0003] I invented a "hydraulic synchronizer" in August 2006. The patent number is 2006100698771. It is equipped with an input shaft, an output shaft, a rotating body, a bucket wheel, a planetary wheel, and a fusible plug. Composed of left and right end covers, there is a bracket in the rotating body, the bucket wheel is supported on the left end cover and the bracket of the rotating body through the bucket wheel shaft, the planetary wheel is cantilever supported on the bucket wheel shaft, the planetary wheel and the sun gear are internally meshed, and the input shaft is connected to the rotating body Connection, the sun gear is connected with the output shaft, the shortcoming is that the box oil enters the bearing seat through the oil circuit and the throttling device, and then enters the rotating body to participate in the work and adjust the time of soft start. The shortcoming is that the clutch cannot be performed quickly and easy shifting
