Abstract
The utility model relates to an insulating pad, belonging to insulating components used for motors of dust collectors. The insulating pad comprises a transverse plate and a boss, wherein the transverse plate is of a circular sheet shape, the center of the insulating pad is equipped with a first shaft groove, a second shaft groove is arranged on the first shaft groove, the inner wall of the second shaft groove is equipped with knurling, the diameter of the first shaft groove is greater than that of the second shaft groove, and the first and second shaft grooves are coaxially matched. The insulating pad is simple in structure, saves labor and time, and ensures the product quality.
Description
Technical field
The utility model relates to the insulation parts of used for electric engine of cleaner, relates in particular to a kind of insulation spacer.
Background technology
Motor is when running, speed due to rotor, can produce very large heat and vibrations, and a part of motor can produce spark when rotating, in order to guarantee the fail safe of motor, between commutator and upper bearing (metal), use red steel paper sheet, be aided with the glutinous jail of glue, the electrical equipment gap reaching between commutator and upper bearing (metal) meets standard-required.So not only increased labour's input, and the quality of pasting quality depends on workman's qualification.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of insulation spacer.
Technical solutions of the utility model are as follows:
A kind of insulation spacer, comprise transverse slat and boss, described transverse slat is round sheet, described insulation spacer central authorities are provided with the first axial trough, the top of described the first axial trough is provided with the second axial trough, described the second axial trough inwall is provided with annular knurl, and the diameter of described the first axial trough is greater than the diameter of the second axial trough, and described the first axial trough is that concentric coordinates with the second axial trough.
Described insulation spacer is made by fire-retardant nylon.
The beneficial effects of the utility model are, with insulation spacer, replace red steel paper sheet, have avoided the bonding process of glue, have improved production efficiency and product quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model profile;
Fig. 2 is the utility model vertical view;
Wherein: 1, transverse slat; 2, boss; 3, the first axial trough; 4, the second axial trough; 5, annular knurl.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult Fig. 1 and Fig. 2, the utility model comprises transverse slat 1 and boss 2, described transverse slat 1 is round sheet, described insulation spacer central authorities are provided with the first axial trough 3, the top of described the first axial trough 3 is provided with the second axial trough 4, described the second axial trough 4 inwalls are provided with annular knurl 5, and the diameter of described the first axial trough 3 is greater than the diameter of the second axial trough 4, and described the first axial trough 3 and the second axial trough 4 coordinate for concentric.
Described insulation spacer is made by fire-retardant nylon.
Described insulation spacer bottom transverse slat 1 contacts with commutator, described boss 2 contacts with upper bearing (metal) inner ring, the external diameter of described boss 2 is less than the external diameter of bearing inner race, is highly greater than the end play between commutator and bearing, realizes rotor insulation spacer when bearing is pressed into fastened.
Above-mentioned drawings and Examples only, for the utility model is described, do not constitute any limitation protection range of the present utility model.
Claims (2)
