Abstract
The utility model relates to a motor belt pulley convenient to dismount. The motor belt pulley convenient to dismount comprises a motor belt pulley, a motor shaft sleeve, bolts and a screw cap, wherein the motor belt pulleys are buckled in the axial direction, an inter-buckled contact line of the two motor belt pulleys is a sine line, two bolts are arranged on an X axis of each of a front sine line and a rear sine line, the two belt pulleys are connected together through a nut, and a prying port is formed in an end-to-end joint of the inter-buckled line; a rectangular hole is formed in the center of the inter-buckled-type motor belt pulley, one motor shaft sleeve with a rectangular outer circumference and a circular inner circumference is arranged in the rectangular hole, and a key slot which is matched with a key on a motor shaft is arranged in an inner hole of the motor shaft sleeve. The motor belt pulley is designed in an inter-buckled form, the inter-buckled line is the sine line, and the prying port is arranged on the end-to-end joint of the sine line, so that the motor belt pulley is convenient to dismount, the shape of the motor shaft is unnecessary to change through the motor shaft sleeve, and the application of the motor belt pulleys on the existing motor can be guaranteed.
Description
Technical field
The utility model relates to a kind of pumping-unit motor belt pulley, specifically a kind of reassembling type motor pulley of being convenient to.Solve the problem of pumping-unit motor belt pulley dismounting difficulty.
Background technique
At present the oil-field oil pumper motor pulley all is casting integrated belt pulley, and is connected with keyway by key between the motor shaft.When motor pulley is installed, be to pound on the key of motor shaft with the keyway that big hammer-harden is taken turns motor pulley, cooperation is a kind of hard cooperation.If key and keyway be not to not just during installation, as easy as rolling off a log motor pulley smashed, or motor shaft is injured by a crashing object.During the dismounting belt pulley all is down to strike with sledgehammer, because the position is improper and the space is little, can not pound simultaneously on both sides when pounding motor pulley in addition, often motor pulley is pounded partially, pound to get off more partially more, dismantle and all do not tear open not get off in more than one hour, also often motor pulley is smashed, the discrepant trochus of taking off of several structures is also arranged at present, because the beam pumping unit cement base, uses inconvenience especially than higher, must need plural people to cooperate just and can take off belt pulley, run into motor shaft and cooperate tighter belt pulley, also take off to get off, have to change motor with taking off trochus.The structure of motor pulley is not suitable for on-the-spot dismounting at present.
Summary of the invention
The purpose of this utility model provides a kind of reassembling type motor pulley of being convenient to, and overcomes the problem that is difficult to dismounting that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model comprises motor pulley, motor shaft sleeve, bolt and nut, it is characterized in that motor pulley is made as first and second and axially goes up button type, the make-up Line of contact that motor pulley is two is made as sinusoidal line, on the X-axis line of front and back sinusoidal line, be provided with two bolts, by nut two belt pulleys are linked together, locate to be provided with the sled mouth with one voice at the head and the tail of make-up line; Be provided with a rectangular opening at button type motor pulley center, be provided with a periphery in the rectangular opening and be that week is circular motor shaft sleeve in the rectangle, be provided with the keyway that cooperates with key on the motor shaft on the endoporus of motor shaft sleeve.
The utility model is made as two button types, and the make-up line is a sinusoidal line, and sinusoidal line is provided with the sled mouth from beginning to end in addition, easy accessibility, and the setting of motor shaft sleeve need not change the motor shaft shape, has guaranteed that this motor pulley uses on existing motor.

The plan view of Fig. 2-Fig. 1;
First motor pulley of 1-among the figure, 2-bolt, 3-motor shaft sleeve, second motor pulley of 4-, 5-are prized mouth.
Embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises motor pulley, motor shaft sleeve 3, bolt 2 and nut, it is characterized in that motor pulley is made as first and second and axially goes up button type, the make-up Line of contact that motor pulley is two is made as sinusoidal line, on the X-axis line of front and back sinusoidal line, be provided with two bolts 2, by nut two belt pulleys are linked together, locate to be provided with sled mouth 5 with one voice at the head and the tail of make-up line; Be provided with a rectangular opening at button type motor pulley center, be provided with a periphery in the rectangular opening and be that week is circular motor shaft sleeve 3 in the rectangle, be provided with the keyway that cooperates with key on the motor shaft on the endoporus of motor shaft sleeve 3.
When motor pulley is installed, earlier motor shaft sleeve 3 is installed on the motor shaft, again first motor pulley 1 and second 4 pairs of motor pulley are buckled on the motor shaft sleeve 3, screw on bolt 2 and nut promptly are installed in motor pulley on the motor shaft.If when transferring the pumping unit jig frequency to change belt pulley, do not dismantle motor shaft sleeve, lay down bolt, once prizing motor pulley is unloaded down at a sled mouthful place with the large size screw-driver, convenient and swift.
