The cavity for accommodating the jam plate folder folding is formed on shape belt pulley, the jam plate folder includes the main jam plate being oppositely arranged and secondary lock
It plate, the spring being fixedly connected between the main jam plate and the secondary jam plate and is separately formed in the main jam plate and the secondary lock
The reversed acanthoid denticle of plate lateral surface forms the tooth socket matched with denticle inside the straight hole shape belt pulley.
Preferably, the hinge joint of the main jam plate and the secondary jam plate is overlapped with the axial line of the motor shaft.
Preferably, the denticle has guiding surface and the patch perpendicular to the main jam plate and the secondary jam plate lateral surface
Conjunction face.
Preferably, it is 110 °~120 ° that the main jam plate and the secondary jam plate, which open included angle B,.
Preferably, after the main denticle and the tooth socket fit, the outer end face of the main jam plate and the secondary jam plate with
Sealing of motor spindle end face flushes.
Preferably, also opposite on the outer end face of the main jam plate and the secondary jam plate form convex block.
The utility model has the beneficial effects that: by pliers be sandwiched in convex block make jam plate folder closure after, straight hole shape belt pulley
Across jam plate folder and motor shaft clearance fit, rotation straight hole shape belt pulley is formed until accommodating the cavity of jam plate folder folding, is loosened
Jam plate folder, under the action of the spring, denticle be embedded in tooth socket, can be completed straight hole shape Pulley shaft to through to limit；Disassembly
When, pliers is sandwiched in after convex block makes jam plate folder closure, straight hole shape belt pulley is pulled out with a hand, without replacing skin after dismantling complete machine
Belt wheel, it is time saving and energy saving, it ensure that the position precision of motor.
Detailed description of the invention:
Fig. 1 is the schematic side view of the utility model；
Fig. 2 is that Figure 1A-A locates half-section diagram；
In attached drawing: 1, straight hole shape belt pulley 2, motor shaft；3, jam plate presss from both sides；4, main jam plate；5, secondary jam plate；6, spring；7, tooth
Body；8, tooth socket；9, guiding surface；10, binding face；11, convex block；12, bearing.
Specific embodiment:
As shown in Figs. 1-2, bayonet type motor belt wheel mounting structure, including straight hole shape belt pulley 1, bearing 12 and motor shaft
2, for 1 sleeve of straight hole shape belt pulley in described 2 one end of motor shaft, the recline straight hole shape belt pulley 1 of the bearing 12 is fixed
In on motor shaft 2, openable and closable jam plate folder is hinged with positioned at the axle center of the motor shaft 2 of described 1 one end of straight hole shape belt pulley
3, the cavitys for accommodating 3 folding of jam plate folder, the jam plate folder 3 are formed on the motor shaft 2 and the straight hole shape belt pulley 1
Including the main jam plate 4 that is oppositely arranged and secondary jam plate 5, the spring 6 being fixedly connected between the main jam plate 4 and the secondary jam plate 5
Be separately formed inside the reversed acanthoid denticle 7 of the main jam plate 4 and secondary 5 lateral surface of jam plate, the straight hole shape belt pulley 1
Form the tooth socket 8 matched with denticle 7.
Specifically, the hinge joint of the main jam plate 4 and the secondary jam plate 5 is overlapped with the axial line of the motor shaft 2.
Specifically, the denticle 7 has guiding surface 9 and perpendicular to 5 lateral surface of the main jam plate 4 and the secondary jam plate
Binding face 10, this setting straight hole shape belt pulley 1 can be carried out through to limit, prevent straight hole shape belt pulley 1 from skidding off motor shaft
2。
Specifically, it is 110 °~120 ° that the main jam plate 4 and the secondary jam plate 5, which open included angle B,.
Specifically, the denticle 7 with after the tooth socket 8 cooperation, the outer end face of the main jam plate 4 and the secondary jam plate 5 with
2 end face of motor shaft.
Specifically, also opposite on the outer end face of the main jam plate 4 and the secondary jam plate 5 to form convex block 11, this setting side
