Embodiment
In Fig. 1, a kind of overload of mud scraper sprocket wheel, unbalanced load protection device, it includes a sprocket wheel 1 and an adapter sleeve 2.
As shown in figure 1, adapter sleeve 2 includes sleeve 201 and terminal pad 202, the sleeve 201 and terminal pad 202 are coaxially, integrally
Shaping.
In Fig. 1, sprocket wheel 1 is sleeved on sleeve 201, and it coordinates with the gap of sleeve 201.As shown in figure 1, for sprocket wheel 1
Axial limiting, the end face of sprocket wheel 1 are resisted against on a side end face of terminal pad 202, and its other end is by being connected on sleeve 201
The axial limiting of back-up ring 3.
As shown in figure 1, offering connection through hole 4 with corresponding respectively on sprocket wheel 1 in terminal pad 202, passed through in connection through hole 4
It is installed with torque protection pin 5.
The broken circumpolar for being no more than torque protection pin 5 in driving torque is prescribed a time limit, and torque protection pin 5 is the drive connection of sprocket wheel 1 set 2
Rotate and driving torque, the coaxial, synchronous axial system with sprocket wheel 1 under the transmission of sprocket wheel 1 of adapter sleeve 2 are provided.Exceed in driving torque and turn round
The broken circumpolar of guard pin 5 of trying hard to keep is prescribed a time limit, and torque protection pin 5 is twisted off, and sprocket wheel 1 is rotated further on the sleeve 201 of adapter sleeve 2, even
Female connector 2 be no longer driven by sprocket wheel 1 and with sprocket wheel 1 is coaxial, synchronous axial system.
As shown in FIG. 1 to 3, a curved wedge surface groove 6 is opened up on the end face of terminal pad 202 in sprocket wheel 1, in terminal pad
Curved wedge surface groove 6 is corresponded on 202 and opens up a pin-and-hole 7, an alignment pin 8 coordinates in curved wedge surface groove 6 through the pin-and-hole 7.Turning round
After guard pin 5 of trying hard to keep is twisted off, curved wedge surface groove 6 relatively rotates with pin-and-hole 7, and alignment pin 8 is pushed away by the groove face of curved wedge surface groove 6
Go out, it is through the protruding adapter sleeve 2 of pin-and-hole 7.
As shown in figure 1, being externally provided with a shake-up ring 9 in a side end face of the terminal pad 202 away from sprocket wheel 1, the outer of ring 9 is being touched
