Description
Technical Field
[0001] The utility model relates to the technical field of motor end covers, in particular to a motor end cover sealing component for a brake pump. Background Art
[0002] As one of the important parts of the motor, the motor end cover mainly plays the role of protecting the internal structure and insulation materials of the motor, sealing the motor space, and preventing debris from entering. At the same time, the motor end cover also plays an important role in sealing the internal medium of the motor. During the operation of the motor, due to factors such as temperature, humidity, and long-term load operation, the lubricating oil and coolant inside the motor are prone to leakage, resulting in motor performance degradation or even failure. Therefore, isolation and insulation treatment of the motor end cover to achieve a sealing effect is a prerequisite for the normal operation of the motor.
[0003] The motor end cover and the motor housing are generally fastened directly with bolts. In order to achieve the sealing effect of the motor housing, a sealing ring is generally provided between the end cover and the motor housing. However, the sealing ring will wear out during long-term use, and the high temperature generated by the long-term use of the motor will also accelerate the damage of the sealing ring. Therefore, the sealing ring needs to be replaced. Traditionally, the replacement of the sealing ring requires the entire end cover to be removed from the motor housing. However, the motor shaft is generally connected to other structures, and the motor shaft passes through the end cover. Therefore, the removal of the end cover also requires the removal of the motor shaft and other parts, and then the end cover can be removed from the motor housing. Therefore, the removal of the motor end cover is more troublesome, and it is not convenient to directly replace the sealing ring. Utility Model Content

[0026] Reference Figure 1-5 , a motor end cover seal for a brake pump, comprising a motor housing 1 and an end cover body 2, characterized in that a circular hole through which a power supply motor shaft passes is provided on the surface of the end cover body 2, a circular groove is provided on the side of the end cover body 2 close to the motor housing 1, a rotating member 3 is rotatably connected inside the circular groove, a circular hole is provided on the surface of the rotating member 3, a bearing sleeve 5 for supporting the motor shaft is fixedly installed inside the circular hole, a sealing gasket 4 is provided on the side of the rotating member 3 away from the end cover body 2, the sealing gasket 4 is set as an annular structure, the diameter of the sealing gasket 4 is larger than the diameter of the rotating member 3, the middle of the sealing gasket 4 is in a disconnected state, the end cover body 2 is fastened to the motor housing 1 by bolts, and when the sealing gasket 4 needs to be replaced, the bolts are directly loosened to leave a gap between the end cover body 2 and the motor housing 1 A certain gap is left, and then the old sealing gasket 4 can be directly pulled out. When installing a new sealing gasket 4, one end of the sealing gasket 4 can be held to install it with the rotating part 3, and then the sealing gasket 4 can be installed step by step. During the installation process, in order to facilitate the installation position to always be at the top, the rotating part 3 can be rotated along with the installation of the sealing gasket 4 until the entire sealing gasket 4 is completely installed. The bearing sleeve 5 installed in the circular hole inside the rotating part 3 can allow the motor shaft to pass through and support the motor shaft to improve the stability of the motor during use. The sealing gasket 4 is set to a disconnected state, so as to facilitate the installation of the sealing gasket 4 without completely disassembling the end cover body 2, and avoid the situation where the sealing gasket 4 cannot be sleeved on the motor shaft due to the use of a closed annular sealing gasket 4.
[0027] Furthermore, a slot 8 is provided on one side of the rotating part 3 close to the sealing gasket 4. The slot 8 is an annular structure, and the inner wall outer circle of the slot 8 is recessed inward. The sealing gasket 4 is composed of a first thickened pad 41 and a second thickened pad 42. The second thickened pad 42 and the slot 8 are adapted in shape. A slot 8 is provided on the rotating part 3, and the sealing gasket 4 is embedded and engaged with the slot 8 using the second thickened pad 42, so that it will not fall off while being installed during the installation process, thereby improving the convenience of installation. The diameter of the first thickened pad 41 is relatively large, and can completely seal the end cover body 2 and the motor housing 1.
[0028] Furthermore, a rotating groove 6 is opened on the inner wall of the circular groove of the end cover body 2, and a rotating ring 9 is fixedly installed on the side of the rotating part 3 close to the end cover body 2. The rotating ring 9 and the rotating groove 6 are movably connected. The rotating part 3 is connected to the end cover body 2 by the rotating ring 9, so that the rotating part 3 can be rotated or slid left and right, which helps to improve the convenience of installing the sealing gasket 4.
[0029] Furthermore, a circumferential array of limiting teeth 14 is provided on one side of the rotating part 3 close to the end cover body 2, and a circumferential array of limiting grooves 7 is provided on the inner wall of the circular groove of the end cover body 2. By providing the limiting teeth 14 and the limiting grooves 7, when the end cover body 2 and the motor housing 1 are fastened together, the rotating part 3 will be squeezed on both sides, so that the rotating part 3 can be stably engaged on the end cover body 2 by using the limiting teeth 14 and the limiting grooves 7, thereby preventing the motor shaft from driving the rotating part 3 to rotate, thereby preventing the sealing gasket 4 from being worn.
[0030] Furthermore, two receiving grooves 11 are provided inside the end cover body 2, and the two receiving grooves 11 both pass through the right side of the end cover body 2, and a round block 12 is slidably connected inside the receiving groove 11, and a spring 10 is fixedly installed on the side wall of the round block 12, and the end of the spring 10 away from the round block 12 is fixedly connected to the receiving groove 11, and the end of the round block 12 away from the spring 10 is movably connected to a steel ball 13. During the installation of the sealing gasket 4, the rotating part 3 needs to be disengaged from the limiting groove 7. Therefore, when the end cover body 2 is away from the motor housing 1, the set round block 12 will be subject to the elastic force of the spring 10, so that the steel ball 13 extends out of the receiving groove 11 and pushes the rotating part 3, so that the rotating part 3 uses the rotating ring 9 to move outward a certain distance, thereby limiting the tooth teeth 14 from being completely disengaged from the limiting groove 7, so that the rotating part 3 can be rotated to achieve the purpose of assisting the installation of the sealing gasket 4, and the steel ball 13 and the round block 12 are movably connected, so when the steel ball 13 contacts the rotating part 3, it will not cause resistance to the rotating part 3.
[0031] Furthermore, the diameter of the receiving groove 11 near the rotating member 3 is smaller to prevent the round block 12 from escaping from the receiving groove 11, and the diameter of this part is larger than the steel ball 13 to allow the steel ball 13 to pass through.
[0032] In summary, the end cover body 2 is fastened to the motor housing 1 by bolts. When the gasket 4 needs to be replaced, the bolts are directly loosened to leave a certain gap between the end cover body 2 and the motor housing 1, and then the old gasket 4 can be directly pulled out. When installing a new gasket 4, one end of the gasket 4 can be held to install it with the rotating part 3, and then the gasket 4 can be installed step by step. During the installation process, in order to facilitate the installation position to always be at the top, the rotating part 3 can be rotated along with the installation of the gasket 4 until the entire gasket 4 is completely installed and the rotating part 3 is installed. The bearing sleeve 5 installed in the internal circular hole allows the motor shaft to pass through and supports the motor shaft to improve the stability of the motor in use. The sealing gasket 4 is set to a disconnected state, so that it is convenient to install the sealing gasket 4 without completely disassembling the end cover body 2, avoiding the situation where the sealing gasket 4 cannot be sleeved on the motor shaft due to the use of a closed annular sealing gasket 4. A card slot 8 is provided on the rotating member 3, and the sealing gasket 4 is embedded and engaged with the card slot 8 using the second thickening pad 42, so that it will not fall off while being installed during the installation process, thereby improving the convenience of installation. The diameter size of the first thickening pad 41 is relatively large. The end cover body 2 and the motor housing 1 can be completely sealed. The rotating member 3 is connected to the end cover body 2 by a rotating ring 9, so that the rotating member 3 can be rotated or slid left and right, which helps to improve the convenience of installing the sealing gasket 4. By setting the limiting teeth 14 and the limiting groove 7, the rotating member 3 can be squeezed on both sides when the end cover body 2 and the motor housing 1 are fastened, so that the rotating member 3 can be stably engaged on the end cover body 2 by the limiting teeth 14 and the limiting groove 7, thereby preventing the motor shaft from driving the rotating member 3 to rotate, thereby causing wear to the sealing gasket 4. The phenomenon that the rotating part 3 needs to be disengaged from the limiting groove 7 during the installation of the sealing gasket 4, therefore, when the end cover body 2 is away from the motor housing 1, the provided round block 12 will be subjected to the elastic force of the spring 10, so that the steel ball 13 extends out of the accommodating groove 11 and pushes the rotating part 3, so that the rotating part 3 uses the rotating ring 9 to move outward a certain distance, thereby limiting the complete disengagement of the teeth 14 from the limiting groove 7, so that the rotating part 3 can be rotated to achieve the purpose of assisting the installation of the sealing gasket 4, and the steel ball 13 and the round block 12 are movably connected, so when the steel ball 13 contacts the rotating part 3, it will not cause resistance to the rotating part 3.
