Description
Technical field
The present invention relates to the technical field of farm machinery, it is specifically a kind of it is responsible engagement or dialysis power transmit carry bone
The wet clutch of frame oil sealing.
Background technology
Agricultural machine is essential dynamic power machine in modern agricultural production, the clutch that the transmission device of agricultural machine uses
It is the belt pulley type clutch of external, this belt pulley type clutch is mounted in engine and gearbox（Gear mechanism）It
Between, it is responsible for the engagement and dialysis of power and transmission system.It relies on and rubs between the driving link and driven member of belt pulley type clutch
Pad transmits torque, ensures the smooth-going when gentle start and shift of agricultural machine, also prevents the overload of transmission system.
The agricultural machine of the prior art continues to use always dry type without oil type belt pulley type clutch in decades.Dry type is without oil type
Belt pulley type clutch mainly includes clutch shaft, belt pulley and belt wheel set lid, and belt pulley and belt wheel set lid enclose
Cavity be built-in with friction plate, between clutch shaft and belt wheel set lid be equipped with axle envelope, the axle envelope be used in fording operation prevent
Sealing enters in the cavity of clutch.There is prodigious defects without oil type belt pulley type clutch for this dry type：1, dry type without
For oil type belt pulley type clutch due to oil-free lubrication, intracavitary friction plate is slightly long in the discrete state duration, can cause to rub
Piece is burnt and early stage wear out failure because dry friction is rapidly heated.2, dry type without oil type belt pulley type clutch due to without glossy
Sliding, the isolation sealing component in belt pulley type clutch can only use loose waterproof rubber ring；Once using the anti-of tight fit
Water rubber ring, then the waterproof rubber ring can be risen in belt pulley type clutch operation process medium temperature because of oil-free lubrication and oil-free cooling
It is high and burn out；And loose waterproof rubber ring can cause agricultural machine in fording operation in belt pulley type clutch cavity water inlet make
It skids at friction plate group, frictional force is insufficient and the transmission effect that runs out of steam, friction plate assembly（Containing fixed plate and connecting screw etc.）
The problems such as touching water also and can get rusty damage.Above-mentioned factor causes the functional reliability of the belt pulley type clutch of existing agricultural machine
It is low.Therefore, people have developed using the belt pulley type clutch that lubricating oil is cooling and lubricates, and open source literature also reports some profits
With lubricating oil is cooling and the belt pulley type clutch of lubrication, such as：
1, Chinese patent：Belt pulley type clutch and agricultural machine, application number：201220554104.3 applying date 2012.10.26,
Patentee：China of Guangxi Luzhai county opto-mechanical manufactures Co., Ltd, address：545600 Liuzhou City, GuangXi Zhuang Autonomous nationality District deer
The centers Zhai Xian industrial park inlet, inventor：Lin Jianwu, abstract：The invention discloses a kind of belt pulley type clutch and agricultures
With machine, it is related to manufacture of agricultural machinery technical field, the belt pulley type clutch wherein used in agricultural machine is：Top cover be sleeved on from
On clutch axis, top cover positive stop lug boss abuts against on the inside of belt wheel set lid, and belt wheel set lid connects over pulleys carried.Pass through top cover ring
The oil sealing in 0 type circle and belt wheel set bezel ring, type groove in type groove can inject oil into the pre- tightening seal of clutch shaft
Belt pulley type clutch intracavitary, to which the traditional agricultural machine belt pulley type clutch of effective solution is due to oil-free lubrication, chamber
Inner attrition piece is burnt and belt pulley type clutch when early stage wear out failure, agricultural machine are in fording operation because dry friction is rapidly heated
Water inlet causes friction plate to skid in cavity, and frictional force is insufficient and the transmission effect that runs out of steam, friction plate touches water can also get rusty
The problems such as damage.
