Abstract

The utility model discloses a conjoined type bearing chamber for plastic packaged motors belonging to the technical field of the motor machining, comprising a plastic packaged casing 3 which is provided with a stator 9, a bearing chamber 10. The conjoined type bearing chamber for plastic packaged motors is characterized in that the bearing chamber connected with the plastic packaged casing into a whole as a conjoined type structure, the bearing chamber can be sheathed with a shock ring 2. The utility model changes the structure type of the prior art that the metal bearing chamber is fixed on the plastic packaged casing by screw bolts, the rivets, or the wedge pressure, the manufacturing process and the assembly process are simplified; the conjoined type bearing chamber for plastic packaged motors has the advantages of simple structure, high positioning accuracy, small running noise, etc. The safety and the reliability of the motor is effectively improved.

Description

Plastic packaging motor Contiuum type bearing chamber

The utility model relates to a kind of plastic packaging motor Contiuum type bearing chamber, belongs to the motor manufacturing technology field.

The bearing chamber of existing plastic packaging motor generally adopts metal material, press solidly on the plastic packaging casing of plastic packaging motor with bolt, rivet or embedding when assembling, its positioning accuracy is not high, and assembly technology is had relatively high expectations, and noise is bigger in the running, has influenced the manufacturing and the result of use of plastic packaging motor.

The purpose of this utility model provides a kind of reasonable in design, and effectively simplified manufacturing technique improves precision, reduces the plastic packaging motor Contiuum type bearing chamber of noise.

The utility model is a plastic packaging motor Contiuum type bearing chamber, comprises the plastic packaging casing of being with stator, and bearing chamber is characterized in that described bearing chamber and plastic packaging casing are the Contiuum type structure that fuses.The Contiuum type structure capsulation material encapsulated moulding of this bearing chamber and plastic packaging casing, the material of described bearing chamber and cabinet can be for containing the thermoset plastics of filler; Described bearing chamber also can be with shock absorbing ring outward.Also can seal in the described plastic packaging casing and be provided with the circuit for controlling motor plate.

The utility model adopts bearing chamber and plastic packaging casing Contiuum type structure, bearing chamber and plastic packaging casing are carried out whole plastic packaging, reasonable in design, and manufacturing and assembly technology have been simplified, having changed metal bearing chamber in the prior art adopts bolt, rivet or embedding to press solidly version on the plastic packaging machine shell when assembling, overcome in the prior art because parts are many, need assembling each other and cause that precision is not high, defective such as complex process, noise are bigger.The utlity model has simple in structure, positioning accuracy height, low remarkable advantage and the good effect of waiting of running noise, bearing chamber is with shock absorbing ring outward simultaneously, be convenient to that plastic packaging motor is carried out elasticity and install, make it to have more the effect of shockproof damping, and can further reduce noise; And with circuit for controlling motor plate plastic packaging in the plastic packaging casing, then can make the motor overall structure compact more.The utility model supporting use on monophase ac capacitance-run formula motor or brshless DC motor that suits can effectively improve the security performance and the unfailing performance of motor.

Accompanying drawing has provided structure cutaway view of the present utility model.

10 is bearing chamber among the figure; 2,6 is shock absorbing ring; 3 is the plastic packaging casing; 1,8 is bearing; 4 is rotor; 5 is end cap; 7 are rotating shaft; 9 is stator; 11 is the circuit for controlling motor plate.

Below be example with the plastic packaging brshless DC motor, the utility model is further described.

Earlier stator 9 and circuit for controlling motor plate 11 are put into the plastic package die positioning and fixing that designs bearing chamber and plastic packaging machine shell model, mould is put on the injection molding machine then, select for use the mylar or the thermoset plasticses such as epoxy resin or phenolic resins that contain filler on injection moulding machine, to carry out encapsulated moulding, envelope is provided with the plastic packaging casing 3 of circuit for controlling motor plate 11 stators 9 in making, the end face projection of its plastic packaging casing is bearing chamber 10, and puts rubber shock-absorbing circle 2 outside bearing chamber.During assembling, the plastic packaging casing is put in the rotating shaft 7 of band rotor 4 and bearing 1,8, bearing 1 is embedded in the bearing chamber 10,, at last another shock absorbing ring 6 is placed on the end cap 5 at plastic packaging casing other end cover upper end cover 5 and fixing.The utility model will be arranged at the outer circuit for controlling motor plate plastic packaging of motor in the plastic packaging casing in the former brshless DC motor, make structure of the present utility model compact more, can further improve insulation property and operating reliability.
