Abstract
A taper sleeve type motor belt pulley comprises a disassembly bolt, a disassembly nut, a connecting bolt, a spring pad, a flat pad, a taper sleeve, and a belt pulley. The taper sleeve type motor belt pulley is characterized in that an annular assembly gap is formed on the left end surface of the taper sleeve type motor belt pulley, three threaded blind holes are formed on the end surface of the assembly gap, an annular hole cavity is formed on the right end surface of the taper sleeve type motor belt pulley, five connected grooves are formed on the outer periphery of the belt pulley, and a taper hole with the same taper as that of the outer periphery of the taper sleeve is formed at the center of the belt pulley; and a hole matched with a motor shaft and a key groove are formed at the center of the taper sleeve, the taper of the outer periphery of the taper sleeve is 1:14, the annular disassembly nut is arranged at the left end of the taper sleeve, a threaded hole smaller than the motor shaft hole is formed at the center of the annular disassembly nut, three assembly holes and threaded through holes are alternately formed on the end surface of a large annular boss of the tape sleeve, a symmetric open groove is formed at the left tapered part of the tape sleeve in the radial direction perpendicular to the key groove, and a horizontal section is arranged between the tapered part and the assembly gap. The taper sleeve type motor belt pulley has convenient assembly and disassembly and good safety and reliability, and can reduce labor intensity for workers and improve work efficiency.
Description
Technical field
The utility model relates to a kind of taper sleeve type motor pulley, belongs to the F16H55/17 class.
Background technique
At present in the oilfield pumping well production process, because it is regular work that production needs the adjustment of pumping unit jig frequency, existing " pumping-unit motor the loads and unloads belt pulley fast " patent No.: ZL200820022845.0, there is following shortcoming: the one, when taking off, lining still needs to take out with pulley extractor, operate constant; The 2nd, entity structure heaviness, waste material.Thereby prior art can not address the above problem.
Summary of the invention
Technical problem to be solved in the utility model is a kind of taper sleeve type motor pulley of design, solves the belt pulley lining and is difficult to take off problem with heavy waste material.
The utility model comprises: demounting bolt, dismounting nut, connecting bolt, spring pad, plain cushion, tapered sleeve, belt pulley; It is characterized in that: described taper sleeve type motor pulley left side is provided with ring assembling space, on the end face in assembling space, be provided with three tapped blind holes, the right side is provided with the ring vestibule, to alleviate belt pulley weight, economical with materials, be beneficial to assembling, the belt pulley cylindrical is provided with five related grooves, and the center is provided with and the identical tapered hole of tapered sleeve cylindrical tapering; The tapered sleeve center is provided with the hole with the motor shaft coupling, and be provided with keyway, tapered sleeve cylindrical tapering is 1: 14, left end is provided with annular dismounting nut, and the center is the tapped hole less than motor axis hole, is provided with three pilot holes and tapped through hole on the end face of tapered sleeve circle ring boss, and open each other in two kinds of holes, tapered sleeve left end tapering part upwards is provided with a symmetrical opening slot in the footpath perpendicular to keyway, in the middle of tapering part and the assembling space horizontal segment is arranged, so that close fit.
According to the taper sleeve type motor pulley that such scheme is made, easy installation and removal, safe and reliable; Alleviate working strength of workers, increase work efficiency; Reduce stopping the well time of oil well, rate when improving well recovery increases crude output.

Embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
This taper sleeve type motor pulley comprises: demounting bolt 1, dismounting nut 2, connecting bolt 3, spring pad 4, plain cushion 5, tapered sleeve 6, belt pulley 7; It is characterized in that: described taper sleeve type motor pulley left side is provided with ring assembling space a, on the end face of assembling space a, be provided with three tapped blind holes, the right side is provided with ring vestibule b, and the belt pulley cylindrical is provided with five related grooves, and the center is provided with and the identical tapered hole of tapered sleeve cylindrical tapering; Tapered sleeve 6 centers are provided with the hole with motor shaft 8 couplings, and be provided with keyway, tapered sleeve 6 cylindrical taperings are 1: 14, left end is provided with annular dismounting nut 6, the center is the tapped hole less than motor axis hole, is provided with three pilot holes 11 and tapped through hole 10 on the end face of tapered sleeve 6 circle ring boss, and open each other in two kinds of holes, tapered sleeve 6 left end taperings part upwards is provided with a symmetrical opening slot c in the footpath perpendicular to keyway, in the middle of tapering part and the assembling space a horizontal segment is arranged.
The utility model is fastening by three connecting bolts 3 are carried out, and belt pulley 7 and tapered sleeve 6 are closely linked.When pretightening force reaches one regularly, the opening slot c of tapered sleeve 6 shrinks, and holds tightly on motor shaft.When need changing belt pulley 7,,, can unload pine to belt pulley 7, screw in dismounting nut 2, can pull down tapered sleeve 6 with demounting bolt 1 at three other tapped through hole 10 equilibriums connecting bolt 3 of screwing on as long as draw off three connecting bolts 3.During normal the operation, it is standby that demounting bolt 1 unloads appropriate preservation.
