Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of motors, and in particular relates to a motor housing which is convenient for throwing out oil dirt inside the motor. Background Art
[0002] The motor consists of two parts: the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is the rotating part of the motor. After a long period of use, the oil smoke of a general kitchen motor will enter the motor through the gap at the connection of the motor housing, and then adhere to the motor rotor. It is difficult to remove the oil during operation, which will cause damage to the motor. The oil attached to the inside of the motor will make it difficult for the motor to dissipate heat, which will further reduce the service life of the motor. Summary of the invention
[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a motor housing which is convenient for throwing out the oil dirt inside the motor.
[0004] The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a motor housing which is convenient for throwing out the oil and dirt inside the motor, including a motor housing, the motor housing being a housing structure which is through-through from front to back, a step being provided at the front end of the inner cavity of the motor housing, a bearing mounting housing being provided on the step, the bearing mounting housing being fixedly connected to the step, and the two being coaxially arranged, a supporting bearing being provided in the bearing mounting housing, an end cover mounting sink being provided on the rear end surface of the motor housing, a motor rear end cover being provided in the end cover mounting support, the motor rear end cover being sealed and fixedly connected to the end cover mounting support, a plurality of oil drain holes being provided in a circular array along the axis of the motor housing on the rear end cover of the motor and the step in the motor housing.
[0005] Preferably, the oil drain holes penetrate the step and the rear end cover of the motor.
[0006] Preferably, the step and the motor housing are an integral structure.
[0007] Preferably, the front end surface of the bearing mounting housing is flush with the front end surface of the motor housing.
[0008] The utility model has the beneficial effects that oil drain holes are respectively provided on the motor housing and the rear end cover of the motor, and when the motor runs at a high speed, the rotor generates heat to melt the attached oil stains, and the oil stains are thrown out from the oil drain holes on the front and rear sides by utilizing centrifugal force, and the provision of the oil drain holes can increase the air flow inside the motor, thereby reducing the temperature of the motor. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural schematic diagram of the utility model.
[0010] In the figure: 1. Motor housing; 2. Step; 3. Bearing mounting housing; 4. Support bearing; 5. End cover mounting sink; 6. Motor rear end cover; 7. Oil drain hole. DETAILED DESCRIPTION
[0011] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0012] Embodiment: A motor housing that facilitates the removal of oil stains inside the motor, such as Figure 1 As shown, it includes a motor housing 1, which is a housing structure that is through-through from front to back, a step 2 is provided at the front end of the inner cavity of the motor housing 1, a bearing mounting housing 3 is provided on the step 2, the bearing mounting housing 3 is fixedly connected to the step 2, and the two are coaxially arranged, a supporting bearing 4 is provided in the bearing mounting housing 3, an end cover mounting sink 5 is provided on the rear end surface of the motor housing 1, a motor rear end cover 6 is provided in the end cover mounting support, the motor rear end cover 6 is sealed and fixedly connected to the end cover mounting support, and a plurality of oil drain holes 7 are provided in a circular array along the axis of the motor housing 1 on the motor rear end cover 6 and the step 2 in the motor housing 1.
[0013] The oil drain holes 7 penetrate the step 2 and the rear end cover 6 of the motor; the step 2 and the motor housing 1 are an integral structure; the front end surface of the bearing mounting housing 3 is flush with the front end surface of the motor housing 1.
[0014] The principle of the utility model is as follows: when the motor is installed in a heavy oil pollution environment such as a range hood and an integrated stove, the oil smoke will enter the motor through the gap of the motor housing 1. Since the oil smoke enters the motor in the form of fine oil gas, it is difficult to remove the oil pollution formed after a long period of accumulation from the fine gap. Therefore, an oil drain hole 7 is opened on the motor housing 1. When the motor is running at high speed, a large amount of heat will be generated, and the heat will melt the oil pollution. The centrifugal force of the rotor and the air flow will be used to throw the oil pollution inside the motor out from the oil drain port, so as to prevent the oil pollution from accumulating inside the motor and affecting the operation of the motor.
[0015] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
