As final drive shaft and driven shaft need to adjust coaxiality error in assembling, and the size of coaxiality error will directly affect shaft coupling
Transmission accuracy, traveling comfort and the life-span of operation are driven, current shaft coupling joins after driving shaft and driven shaft install
Difficulty typically can not be dismantled or dismantled to the drive link of axle device, and driving shaft and driven shaft each can not be rotated individually, therefore two
The calibration measurement of coaxiality error between power transmission shaft and adjustment are relatively difficult, when such as changing consumable accessory in maintenance in addition,
What is had must reinstall power transmission shaft part, and readjust its coaxiality error.
The content of the invention
The purpose of this utility model is to provide a kind of shaft coupling, convenient disassembly, can facilitate and accurately calibrate two transmissions
The coaxiality error of axle.
According to a kind of shaft coupling of the utility model embodiment, including：Main coupling head, driven coupling head, movable block, connection
Block, protective case A, protective case B, beam A and beam B, the main coupling head are installed inside the side of driven coupling head
There is rotatable movable block, protective case A, the both ends of the movable block and protective case are fixedly connected with the outside of the main coupling head
Crash roll A is housed between A, the driven coupling head be provided with inside the side of main coupling head can Small-angle Rotation square
The coupling block of shape, it is fixedly connected between protective case B, coupling block and the protective case B on the outside of the driven coupling head and is equipped with
Crash roll B, the movable block are provided with elongated slot close to the side of coupling block, and the coupling block is inserted in the elongated slot of movable block.
Further, spiral shell is passed through between the protective case A and main coupling head and between protective case B and driven coupling head
Bolt is fixedly connected.
Further, the beam A and beam B are made of elastomeric material.
Further, the beam A and beam B are made of polyurethane material.
Further, the rotary part of the movable block and coupling block is similar to spherical, and the movable block is close to connection
The side of block is provided with elongated slot, and the coupling block is provided with square projection close to the side of movable block, and the square projection is inserted in length
Leave in groove and between the two gap.
The utility model has an advantageous effect in that compared with prior art：This shaft coupling is equal due to coupling block and movable block
Using formula structure, driving axle part and driven shaft part is inserted radially into assembling, main coupling head and driven coupling head can be removed
On protective case A, protective case B, after beam A and beam B, from radially loading, tear coupling block open, couple driving shaft and driven shaft
Or disengage.In disengaged condition, each self energy of two axles individually rotates for driving shaft and driven shaft, so as to calibrate conveniently and accurately two
The coaxiality error of power transmission shaft.Mechanically apply, while remove and install conveniently in precision drive for this this shaft coupling is particularly suitable
Advantage is provided for the operational maintenance maintenance of shaft coupling.
