Abstract
The utility model relates to a spline type belt pulley which is characterized in comprising: a belt pulley(4), a cylinder-shaped variable shaft bushing(2) and at least one group of external splines(3). A through hole(1) and a spline groove(5) which is in match with the electric motor shaft are arranged at the axial direction of the variable shaft bushing(2); more than one group of external splines(3) are arranged at the outer wall of the variable shaft main body(2); spline grooves in match with the external spines(3)are arranged at the axial direction of the belt pulley. The beneficial effect of the utility model is that: due to a plurality groups of variable shaft bushings of the external splines arranged outside of the electric motor shaft, the traditional belt detaching method is changed, making the detaching work easier, reducing the machine halt time, improving the working efficiency, reducing insecure factors.
Description
One, technical field:
The utility model relates to a kind of supplementary equipment of motor, particularly relates to the motor of all kinds of pumping units on a kind of petroleum industry oil recovery well and the spline speed variable belt pulley of motor of other production scene.
Two, background technique:
In petroleum industry, pumping unit is the most frequently used oil recovery mode of production, account for 60% of the whole oil recovery mode of production, it is to rely on power to drive motor to carry out high-speed motion that pumping unit extracts underground crude oil, connect by belt by motor again and go up speed reducer, the high-speed motion of motor is converted into the low-speed motion of gearbox, and the oil well pump that drives the down-hole is produced continuously.But because oil well liquid level generally can high and low situation interim occur, this just requires when liquid level is high, and pumping unit need change big belt pulley to be increased number of strokes and extract fast, and liquid level need change small belt pulley when low and reduces stroke, takes out slowly; Yet, at the scene in, the outer directly suit belt pulley of motor shaft, at the scene in, the original means of dismounting belt pulley impact belt pulley with weight exactly, waste time and energy, and potential safety hazard is arranged, and need dead time longer, have had a strong impact on oil well yield.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of spline speed variable belt pulley of motor of fast quick-detach belt pulley is provided.
Its technological scheme is: be made up of belt pulley (4), cylindrical variable-speed shaft lining (2) and one group of above external splines (3); Through hole (1) and spline (5) in that being axially arranged with of variable-speed shaft lining (2) is complementary with motor shaft are provided with the external splines (3) more than a group on the outer wall of described variable-speed shaft main body (2); The spline that be axially arranged with and the external splines (3) of described belt pulley is complementary.
Described external splines (3) is standard-sized external splines for 3-6 organizes, and the spline of described belt pulley is also organized standard-sized spline for corresponding 3-6.
The side of described belt pulley is provided with exterior siding (6), and is fixing by bolt (7).
The beneficial effects of the utility model are: by add the variable-speed shaft lining that is equiped with many group external spliness at motor shaft; change the conventional method of original dismounting belt pulley, dismantlement work is become simply, reduced dead time; improve working efficiency, also reduced potential safety hazard.
Four, description of drawings:
Accompanying drawing 1 is the structural representation of first kind of embodiment's of the present utility model variable-speed shaft lining;
Accompanying drawing 2 is side sectional views of first kind of embodiment of the present utility model;
Accompanying drawing 3 is sectional views of first kind of embodiment of the present utility model;
Accompanying drawing 4 is side sectional views of second kind of embodiment of the present utility model.
Five, embodiment:
Embodiment 1: its technological scheme is: be made up of belt pulley 4, cylindrical variable-speed shaft lining 2 and four groups of standard-sized external spliness 3; At through hole 1 and the spline 5 that being axially arranged with of variable-speed shaft lining 2 is complementary with motor shaft, on the outer wall of described variable-speed shaft main body 2, be provided with four groups of standard-sized external spliness 3; The standard-sized spline that be axially arranged with and the external splines 3 of described belt pulley is complementary; The side of belt pulley is provided with exterior siding 6, and is fixing by bolt 7, plays attractive in appearance, dustproof and safe effect.
Embodiment 2: its technological scheme is: be made up of belt pulley 4, cylindrical variable-speed shaft lining 2 and six groups of standard-sized external spliness 3; At through hole 1 and the spline 5 that being axially arranged with of variable-speed shaft lining 2 is complementary with motor shaft, on the outer wall of described variable-speed shaft main body 2, be provided with six groups of standard-sized external spliness 3; The standard-sized spline that be axially arranged with and the external splines 3 of described belt pulley is complementary; The side of belt pulley is provided with exterior siding 6, and is fixing by bolt 7, plays attractive in appearance, dustproof and safe effect.
Above-mentioned two kinds of embodiments' using process is as follows:
By add the variable-speed shaft lining that is equiped with the standard-sized external splines of many groups at original motor shaft, situation and the original conventional method of dismantling belt pulley that original motor shaft size differs have been solved, dismantlement work is become simply, reduced dead time, improved working efficiency; Simultaneously, also, saved manufacture cost with the belt pulley standardization.
Claims (3)
1, a kind of spline speed variable belt pulley of motor is characterized in that: be made up of belt pulley (4), cylindrical variable-speed shaft lining (2) and one group of above external splines (3); Through hole (1) and spline (5) in that being axially arranged with of variable-speed shaft lining (2) is complementary with motor shaft are provided with the external splines (3) more than a group on the outer wall of described variable-speed shaft main body (2); The spline that be axially arranged with and the external splines (3) of described belt pulley is complementary.
