Abstract

The utility model relates to a motor shield enclosure installation structure, belonging to the motor production and manufacture technical field. The motor shield enclosure installation structure comprises a motor and a shield enclosure, wherein, the shield enclosure is of a cup-shaped structure and is sleeved on the rear end of the motor. The utility model is characterized in that: a plurality of recesses are arranged on the circumference of the shield enclosure and contacted with the outer wall of the motor. The motor shield enclosure installation structure is simple in structure, can fix the shield enclosure on the motor reliably, have simple assembly process and low production cost, and solve the problems in the prior art that the fixing of the shield enclosure and the motor is not reliable or the fixing mode and assembly process of the shield enclosure and the motor are complicated, the cost is high and so on.

Description

The motor shielding cover mounting structure

Technical field

The utility model relates to a kind of motor shielding cover mounting structure, belongs to the technical field that motor is manufactured.

Technical background

For reducing spark produces on the DC motor commutator electromagnetism to the equipment that uses direct current machine or the interference of occasion, the normal mode that installs radome additional at motor back segment end that adopts solves.In the prior art, shielding is covered with and directly is enclosed within motor rear end and does not add fixing mode, but this mode is in the process of running, and regular meeting comes off because of vibration causes radome; Also have by modes such as welding, screw, fine wire hoop bundles, but these three kinds of mode assembly processes are all complicated, and also increased production cost.

Summary of the invention

It is a kind of simple in structure that the utility model purpose is to provide, can be fixed on radome on the motor reliably, and assembly process is simple, the motor shielding cover mounting structure that production cost is lower, solved complexity of radome that prior art exists and the fixing unreliable or existing radome of motor and motor fixed form assembly process, cost is than problems such as height.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises motor and radome, the cup-shaped structure of radome also is set in motor rear end, it is characterized in that described radome is provided with a dried indent along circumference, described indent contacts with the motor outer wall.Wherein, the indent on the radome is formed towards riveting by die, fixes by the indent that forms towards riveting between radome and the motor, and its structure is comparatively simple, and assembly process is also comparatively simple, and need not other part cooperation, and production cost is lower.

As preferably, the number of described indent is 3-5; Further preferred, the number of described indent is 4.Wherein, the quantity of indent is controlled at 3-5 can guarantee that the location between radome and the motor is reliable on the one hand, and the riveting of dashing of also being convenient to indent is on the other hand processed.

As preferably, described several indents evenly distribute on the circumference of motor shielding cover.Wherein, indent evenly distributes on the radome circumference, can guarantee fixing solid and reliable between radome and the motor on the one hand, and the riveting of dashing of also being convenient to indent is on the other hand processed.

Therefore, the utlity model has simple in structurely, radome can be fixed on the motor reliably, and characteristics such as assembly process is simple, and production cost is lower.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 be Fig. 1 C place structure for amplifying schematic diagram.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: as depicted in figs. 1 and 2, radome 29 is along the circumferential direction total to be formed four indents 31 by interior riveting everywhere, four indents 31 are along evenly distributing on the radome circumference, and indent 31 contacts with the outer surface of motor 30, prevent coming off of radome 29 on the motor 30 thereby radome 29 is fixed on.

Claims

1, a kind of motor shielding cover mounting structure comprises motor and radome, and the cup-shaped structure of radome also is set in motor rear end, it is characterized in that described radome is provided with a dried indent along circumference, and described indent contacts with the motor outer wall.

2, motor shielding cover mounting structure according to claim 1, the number that it is characterized in that described indent are 3-5.

3, rivet connection apparatus for motor shielding cover according to claim 2, the number that it is characterized in that described indent is 4.
