Abstract
The invention discloses a compound speed-increasing hydraulic coupler, which comprises a box and a hydraulic coupling component positioned in the box, and is characterized in that a pump wheel shaft in front of the hydraulic coupling component is coupled with a primary gear speed-increasing mechanism, an input shaft in the primary gear speed-increasing mechanism is supported on the side wall of the box through a bearing, a turbine shaft behind the hydraulic coupling component is coupled with a secondary gear speed-increasing mechanism, and an output shaft of the secondary gear speed-increasing mechanism is supported on the side wall of the box through a bearing. Compared with the prior art, the compound speed-increasing hydraulic coupler is internally provided with the primary gear speed-increasing mechanism and the secondary gear speed-increasing mechanism, so that the rotational speed of the input shaft is obviously increased, and speed-increasing mechanisms don't need to be arranged in front of and behind the coupler in occasions with high requirements on the operating rotational speed. Besides, the compound speed-increasing hydraulic coupler has the advantages of compactness in integral structure, small occupied space, less components, less fault points and convenience in mounting and maintenance.
Description
Technical field

Background technique
Fluid coupling is to utilize liquid kinetic energy and potential energy to come a kind of hydraudynamic drive equipment of transferring power, has stepless speed regulation, improves the startup ability of asynchronous motor; The protection dynamic overload, the load allocating between the even multiple electric motors, separating vibration; Relax and impact; Reliable operation, therefore advantages such as life-span length are used widely in departments such as metallurgy, generating, mine, chemical industry, transportation.Pump wheel shaft in the existing fluid coupling is as the input shaft of fluid coupling; Turbine shaft in the fluid coupling is as the output shaft of fluid coupling, and the occasion that the fluid coupling of this structure is had relatively high expectations to number of moving part is not too suitable, and main cause is not have speed increasing mechanism in the coupler; Can only before coupler, install speed increasing mechanism additional in the practice; Simultaneously after coupler, install speed increasing mechanism additional, this mode takes up room greatly, uses parts many; The fault point is many, brings inconvenience to operation and maintenance.
Summary of the invention
The purpose of this invention is to provide a kind of compact structure, few, the compound acceleration type fluid coupling little, convenient for installation and maintenance, that can have higher output speed that takes up room of parts, overcome the deficiency of existing technology.
Compound acceleration type fluid coupling of the present invention; Comprise casing and the fluid coupling parts that are positioned at casing; Pump wheel shaft before the fluid coupling parts is connected to one-level gear up mechanism, and the input shaft in the one-level gear up mechanism passes through bearings on the sidewall of casing; Turbine shaft after the fluid coupling parts is connected to the secondary gear speed increasing mechanism, and the output shaft in the secondary gear speed increasing mechanism passes through bearings on the sidewall of casing.
Compound acceleration type fluid coupling of the present invention, the gear in the wherein said gear up mechanism is a helical gear; Be equipped with the radial bearing of bearing radial force between Pump wheel shaft and turbine shaft and the casing and bear the thrust-bearing of axial force.
Compound acceleration type fluid coupling of the present invention; Compared with prior art since within it portion be provided with firsts and seconds gear up mechanism; The rotating speed of output shaft is obviously improved; Need not before coupler He behind the coupler, speed increasing mechanism to be set for the demanding occasion of working speed, have compact overall structure, advantage little, that parts are few, the fault point is few, convenient for installation and maintenance takes up room.
