Abstract
The utility model provides a motor belt pulley. The motor belt pulley comprises a belt pulley body. The motor belt pulley is characterized in that the contact surface of the belt pulley body and a belt is provided with patterns in an engraved mode. By enlarging the contact area of the belt and the belt pulley body, the adhesion property is good, sliding friction between the belt and the belt pulley is reduced, and the service life of the belt is prolonged due to the fact that the temperature of the motor belt is lowered in summer. The roughness of the belt pulley and the surface of the belt is improved, and therefore the anti-skid capacity of the belt on rainy days is improved. When the surface area of the belt pulley is increased and the electric work temperature is lowered, the power factor of a motor is improved obviously, and the probability of loss of excitation of the permanent magnet motor is eliminated.
Description
Technical field
The utility model relates to widely used a kind of motor pulley in motor torque transmission process.
Background technique
Belt on oil well motor pulley and motor pulley generally all is exposed among nature.After the motor pulley completion of processing, its surface roughness is generally in 12.5 left and right.In use for some time, it is very bright and clean that its surface becomes motor pulley, and through measuring, its surface roughness is in 0.05 left and right.Because the motor pulley surface roughness diminishes, friction factor between motor pulley and belt diminishes, sliding friction displacement amount between electric motor belt and motor pulley increases, if encounter the sleet sky, electric motor belt and motor pulley are by water-wet, between electric motor belt and belt pulley, friction factor can further reduce, belt on motor pulley can skid and make belt blow in the short time in original place on motor pulley, as in summer, the increase of sliding friction amount, can cause electric motor belt and motor pulley heating, affect working life and the motor operation performance of electric motor belt.
The model utility content
The technical problems to be solved in the utility model is: a kind of motor pulley is provided, can reduces the sliding friction amount between motor pulley and belt, thereby extend motor pulley working life, improve the motor power (output) utilization ratio.
The utility model is to solve the problems of the technologies described above the technological scheme of taking to be: a kind of motor pulley, comprise pulley body, and it is characterized in that: be carved with decorative pattern on pulley body and surface of contact that belt contacts.
Press such scheme, described decorative pattern is recessed and protruding lines line.
Press such scheme, described surface of contact comprises the first surface of contact and the second surface of contact, and the first surface of contact is the surface of contact parallel with the axis of pulley body, and the second surface of contact is the surface of contact tangent with the axis of pulley body.
The beneficial effects of the utility model are:
1, by increasing the area of contact of belt and belt pulley, adhesion property is good, reduces the sliding friction between belt and belt pulley, has reduced the working life of electric motor belt temperature prolongation belt summer; Increase the roughness of belt pulley and belt surface, thereby strengthened the skid resistance of belt in the rainy day.
2, after having increased the surface area of belt pulley and having reduced electronic operating temperature, obvious lifting motor power factor and reduce the probability of magneto loss of excitation.
3, the utility model is simple in structure, is easy to processing.
The accompanying drawing explanation
Fig. 1 is the utility model one embodiment's structural representation.
In figure: 1. pulley body, 2. the first surface of contact, 3. the second surface of contact.
Embodiment
Fig. 1 is the utility model one embodiment's structural representation, on pulley body 1 and surface of contact that belt contacts, be carved with decorative pattern, surface of contact comprises the first surface of contact 2 and the second surface of contact 3, the first surface of contact 2 is the surface of contact parallel with the axis of pulley body, and the second surface of contact 3 is the surface of contact tangent with the axis of pulley body.
Described decorative pattern can be for varied, and in the present embodiment, for ease of processing, decorative pattern is set to recessed and protruding lines line, can directly at former belt pulley body, mill and be processed into.
Claims (3)
1. a motor pulley, comprise pulley body, it is characterized in that: be carved with decorative pattern on pulley body and surface of contact that belt contacts.
2. motor pulley according to claim 1, it is characterized in that: described decorative pattern is recessed and protruding lines line.
3. motor pulley according to claim 1 and 2, it is characterized in that: described surface of contact comprises the first surface of contact and the second surface of contact, the first surface of contact is the surface of contact parallel with the axis of pulley body, and the second surface of contact is the surface of contact tangent with the axis of pulley body.
