Abstract

The utility model relates to a quick-attachable-detachable motor belt pulley, which comprises a belt pulley, a tensioning sleeve, a tensioning screw and a dismounting screw, wherein the tensioning sleeve is sheathed in a tapered center hole of the belt pulley and is fixed with the belt pulley by the tensioning screw; and the tensioning sleeve is fixed with a motor shaft by a key groove. The belt pulley can be assembled and disassembled by rotating the tensioning screw and the dismounting screw without disassembling the tensioning sleeve, thus being conveniently and rapidly replaced in a labor-saving way.

Description

Quick assembling & disassembling motor pulley
Technical field
The utility model relates to a kind of oil-field oil pumper motor pulley, specifically a kind of quick assembling & disassembling motor pulley.
Background technique
The motor pulley ubiquity the problem of dismounting and difficult installation on the present oil-field oil pumper, brings very big trouble for the management of oil well ordinary production, all passes through to transfer stroke and jig frequency to realize because of the beam pumping unit well will change the production system; Transferring jig frequency is to realize through the size that changes motor pulley; Each to change motor pulley all be that sledgehammer is down pounded, and the crowbar sled accidentally just smashes motor pulley or pounds motor reel curved; Not to scrap motor to scrap motor pulley exactly; Cause very big economic loss to the oil field, and labor intensity is big, changes motor pulley and bring very big mental burden for the oil recovery workman.
Summary of the invention
The new purpose of this practicality provides a kind of quick assembling & disassembling motor pulley, solves the problem that motor pulley is inconvenient to load and unload.
The technological scheme of the utility model realizes in the following manner:
The utility model comprises belt pulley, tensioner cover, tensioner screw, it is characterized in that the tensioner cover is enclosed within the conical central hole of belt pulley, is fixed by tensioner screw and belt pulley, and the tensioner cover is fixed through keyway and motor reel; The tensioner cover is made as taper shape; The center is provided with motor shaft hole; On motor shaft hole is vertical, be provided with a keyway; Being provided with two tops in periphery is that bottom, half hole is tensioner screw hole and one the dismounting screw hole in full hole, between 90 ° of angles, have one the longitudinal opening seam from outside to inside in the centre of two tensioner screw holes; The dismounting screw hole is made as the unsealed hole of threaded hole Wednesday/one, and the degree of depth is less than the height of tensioner cover at the bottom of the hole; Belt pulley is made as cylindrical; Periphery has the v belt groove; Be provided with up big and down small tensioner trepanning interior week, the top of the corresponding part of two tensioner screw holes that put in belt pulley and tensioner has half hole of two tensioner screw holes, and the tensioner screw hole that puts with tensioner constitutes a complete tensioner screw hole; The dismounting screw hole corresponding part that puts in belt pulley and tensioner has not threaded dismounting screw hole, and the dismounting screw hole that puts with tensioner constitutes a complete arc groove.
The utility model has solved the problem of motor pulley difficulty or ease dismounting, as long as lay down the tensioner screw with belt pulley and tensioner cover compound mode; Rotation dismounting screw; Bottom the dismounting screw 1/3 withstands belt pulley with exterior portions, makes the tensioner cover take off knot with belt pulley, just can lay down the light wheel of belt pulley; The tensioner cover does not change, and the belt pulley that only changes different size gets final product.

Embodiment
For further disclosing the technological scheme of the utility model, elaborate through embodiment below in conjunction with Figure of description:
The utility model comprises belt pulley A, tensioner cover B, tensioner screw C, it is characterized in that tensioner cover B is enclosed within the conical central hole of belt pulley A, is fixed by tensioner screw and belt pulley, and the tensioner cover is fixed through keyway and motor reel; The tensioner cover is made as taper shape; The center is provided with motor shaft hole; On motor shaft hole is vertical, be provided with a keyway; Being provided with two tops in periphery is that bottom, half hole is the tensioner screw hole C ' and a dismounting screw hole D ' in full hole, between 90 ° of angles, have one the longitudinal opening seam from outside to inside in the centre of two tensioner screw holes; The dismounting screw hole is made as the unsealed hole of threaded hole Wednesday/one, and the degree of depth is less than the height of tensioner cover at the bottom of the hole; Belt pulley is made as cylindrical; Periphery has the v belt groove; Be provided with up big and down small tensioner trepanning interior week, have half hole of two tensioner screw holes on the top of the corresponding part of two tensioner screw holes that put with tensioner, the tensioner screw hole that puts with tensioner constitutes a complete tensioner screw hole C '; Have one not threaded arc groove in the dismounting screw hole corresponding part that puts with tensioner, the dismounting screw hole that puts with tensioner constitutes a complete dismounting screw hole D '.
When using the utility model,, earlier tensioner is overlapped B and be contained on the motor reel if loading and unloading motor pulley fast is installed; Again belt pulley A is enclosed within tensioner and puts, make the alignment of belt pulley A and tensioner cover B both ends of the surface, tensioner screw hole C ' is relatively corresponding separately with dismounting screw hole D '; Two the tensioner screws of screwing on, because of being that taper is nested and combines between tensioner cover and the belt pulley, the tensioner screw is tightly more stubborn; The tensioner cover combines tight more with belt pulley, can uncoupling in the motor operation process.If the replacing belt pulley is laid down the tensioner screw earlier, dismounting screw D screws on; Dismounting screw bottom end 1/3rd places are pressing belt pulley and tensioner cover uncoupling, because both combinations are cone structures, can easily belt pulley be laid down; Need not dismantle the tensioner cover; The belt that directly changes different size gets final product, and is efficient and convenient, time saving and energy saving.
