In, the top of round pin axle is provided with circular shaft roof, is provided with rectangular shape constant head tank at shaft roof top, the clamp plate is rectangular shape, and cross sectional shape and constant head tank cross sectional shape phase-match, length are good at the constant head tank, and the both ends of constant head tank are provided with the bolt hole
The flat head
The outer walls of the two sides of the mounting hole are provided with bolt holes
The bolt hole
Bolt hole
Is matched with the bolt hole
Bolt hole
Are matched.
The cross section of the pressing plate is trapezoidal.
The thread diameter of the bolt is 4-20 mm.
The diameter of the outer edge of the shaft top plate is 20-200 mm larger than that of the bolt.
The beneficial effects of utility model are that: the utility model discloses the device is made and is processed simply, can effectually guarantee driven safe and reliable, prevents that the round pin axle from rotating when equipment operation, moving the defect that causes the transmission inefficacy, avoids equipment to break down, has popularization and application and worth.
