Summary of the invention:
The purpose of the utility model is to provide a kind of main structure to comprise belt pulley (clutch outer member), bearing, clutch core, guard shield, the anti-mud collar of waterproof, bearing cup, clutch pawl, clutch pawl guide pin bushing, clutch seat, the anti-mud cover of waterproof, clutch stay cord, bearing, power input shaft; Belt pulley is bearing in the axle head of power input shaft through bearing; The inner clutch core of installing of belt pulley, guard shield is installed in the hollow side of belt pulley, and circle is installed the anti-mud collar of waterproof in the guard shield; Circle is pressed on the bearing cup outer surface in the anti-mud collar of waterproof; The clutch pawl is enclosed within outside the clutch pawl guide pin bushing, and clutch pawl guide pin bushing is fixed in the clutch seat, and the clutch seat is fixed on the tank wall outer side surface of machine; It is downward that the bigger end of the anti-mud cover of waterproof packs into the cylindrical and the indentation, there of the anti-mud collar ring stiffening rib of waterproof, the less end of the anti-mud cover of waterproof pack on the clutch seat outer round surface and with bolt or screw at clutch seat cylindrical.Can splash into body component such as erosion bearing fulcrum, clutches by the anti-mud of waterproof, simple in structure, easy to manufacture, easy to install, safe and reliable waterproof is prevented the mud cover.
The technical solution of the utility model is such: a kind of clutch waterproof is prevented the mud cover; Comprise belt pulley, clutch shaft bearing, clutch core, guard shield, the anti-mud collar of waterproof, bearing cup, clutch pawl, the anti-mud cover of waterproof, bolt, clutch seat, clutch pawl guide pin bushing, power input shaft, second bearing, clutch stay cord; It is characterized in that in the anti-mud cover of the waterproof inner chamber bearing cup, clutch pawl, second bearing, clutch pawl guide pin bushing, power input shaft, clutch seat being housed; The anti-mud cover of the waterproof large port anti-mud collar of waterproof of packing into; Guard shield covers on the belt pulley large port; The belt pulley inner chamber is installed clutch core, clutch shaft bearing, and the clutch stay cord is connected with clutch pawl latch spoon, and is contained in breach.
The anti-mud of waterproof overlaps the front-end face that big breach is installed in the anti-mud collar of waterproof, and the anti-mud cover of waterproof inner chamber is installed bearing cup, clutch pawl, and clutch pawl internal diameter has clutch pawl guide pin bushing to be inserted in; The dynamic input shaft of clutch pawl guide pin bushing internal diameter is inserted in; The bearing cup internal diameter has second bearing to be inserted in, and the dynamic input shaft of second bearing bore diameter is inserted in, and bearing cup is installed clutch core and clutch shaft bearing, guard shield, belt pulley port with end face; The clutch core is installed in the belt pulley inner chamber; The anti-mud cover of waterproof front end inner chamber is directly installed the clutch seat, and clutch seat internal diameter has clutch pawl guide pin bushing to be inserted in, the dynamic input shaft of clutch pawl guide pin bushing internal diameter.
The anti-mud cover of waterproof is coaxial bicylindrical outer surface, boring, and great circle cylinder one side has breach.
The anti-mud collar of waterproof has band ring stiffening rib, the anti-mud collar external diameter dress of waterproof guard shield, and front end is installed the anti-mud cover of waterproof.
The utility model has the advantages that notched bicylindrical face waterproof prevents the mud cover; The bigger end of the anti-mud cover of waterproof is enclosed within waterproof and prevents that the cylindrical and the breach of mud collar ring stiffener are downward, and a less end packs on the clutch seat outer round surface and with bolt or screw; More than this structure be installed on tillage machine or the microtilling machine and can drench with rain or preventing that Ni Heshui from splashing when tillage machine or microtilling machine work gets into bearing cup the inside bearing rust on rainy day, the space that perhaps gets into the mating face of clutch and clutch pawl increases friction and causes clutch after detachment dynamic, to compare the difficulty power that closes.Simple in structure, easy to manufacture, easy to install, safe and reliable.
