Description

Technical Field

[0001] The utility model belongs to the technical field of motor parts and relates to a motor pressing plate, in particular to a flame retardant and corrosion resistant motor pressing plate. Background Art

[0002] As the core component of the power source, the motor's performance and stability directly impact the overall efficiency of the equipment. To ensure efficient and safe motor operation, engineers have designed a variety of auxiliary structures, including a key component: the motor pressure plate. The motor pressure plate securely connects to the core laminations through mounting holes and keyways, securing the laminations securely within the motor. This securement effectively prevents displacement or loosening of the core laminations due to centrifugal force or vibration during motor operation, ensuring stable motor operation.

[0003] A search revealed a Chinese patent document that discloses a bearing pressure plate and motor [Application No.: 202322864740.7; Publication No.: CN221177484U]. The bearing pressure plate of this motor presses the bearing onto the end cover, allowing it to both tighten the bearing and secure the oil seal.

[0004] Although the bearing pressure plate of the motor disclosed in this patent plays a role in fixing the bearing and the oil seal, the bearing pressure plate is limited to a single bearing specification, resulting in the need to produce corresponding pressure plates for bearings of different specifications, thereby increasing production costs. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a flame retardant and corrosion resistant motor pressure plate. The technical problem to be solved by the utility model is: how to make the motor pressure plate adapt to bearings of various specifications.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A flame retardant and corrosion-resistant motor pressure plate includes a plate body, six slide grooves are evenly opened on the plate body, and clamping parts are provided in the six slide grooves. The clamping part includes a slider, and a mounting block is integrally formed at the bottom of the slider. The mounting block is penetrated by a threaded rod in the vertical direction of the center of the plate body, and the threaded rod is threadedly connected to the mounting block. A handle is welded at one end of the threaded rod away from the center of the plate body, and a resistance block is rotatably connected to the other end of the threaded rod. One end of the slide rod is fixedly connected to the resistance block, and a limit plate is fixed at the other end of the slide rod. A plurality of positioning holes are evenly opened on the top of the plate body on the left and right sides of the slide groove, and bolts are vertically penetrated in the positioning holes. Nuts are threadedly connected to the bolts, and limit blocks are sleeved on the bolts. The limit blocks are fixed on the left and right sides of the slider.

[0008] The working principle of the utility model is as follows: according to the outer diameter specification of the bearing, the positioning hole for bolt installation is selected, the bolt is passed through the corresponding positioning hole from top to bottom, and the nut is turned into the fixed limit block from the bottom of the plate body, thereby realizing the positioning of the slider and the mounting block, the interference block moves with the mounting block through the threaded rod, and the threaded rod is rotated. The threaded transmission between the threaded rod and the mounting block makes the interference block close to the bearing, and the six interference blocks tightly clamp the bearing to realize the fixed installation of the bearing.

[0009] The material of the resistance block is silicone rubber.

[0010] With the above structure, the friction force of the silicone rubber contact block contacting the outer surface of the bearing is stronger, thereby improving the clamping and fixing performance.

[0011] The plate body is provided with a concave edge, an end cover is provided on the concave edge, a sealing ring is fixed on the inner wall of the end cover, and the sealing ring is in contact with the concave edge.

[0012] With the above structure, the circular hole in the center of the end cover passes through the motor output shaft, and the sealing ring contacts the concave edge on the plate body, so that the end cover fits the concave edge, avoiding protrusion and causing invalid space occupation, and improving sealing.

[0013] Three connecting angle pieces are evenly fixed on the bottom of the end cover, and three installation grooves are opened on the top of the plate body. The installation grooves correspond to the positions of the connecting angle pieces, and the connecting angle pieces can slide in the installation grooves.

[0014] With the above structure, when installing the end cover, align the connecting angle piece with the installation slot and press it down. When the connecting angle piece is pressed to the bottom of the installation slot, rotate the end cover clockwise. The connecting angle piece rotates with the end cover and engages with the installation slot, thereby completing the installation of the end cover and facilitating disassembly and assembly.

[0015] A sliding rod is provided below the threaded rod and passes through the mounting block. One end of the sliding rod is fixedly connected to the abutment block, and the other end of the sliding rod is fixed with a limiting piece.

[0016] With the above structure, when the mounting block moves with the threaded rod, the sliding rod plays a limiting role, preventing the mounting block from rotating with the threaded rod, making the movement of the mounting block more stable.

[0017] Compared with the existing technology, this flame retardant and anti-corrosion motor pressure plate has the following advantages:

[0018] 1. The initial clamping of the bearing is achieved by setting a slidable slider and using bolt positioning. The threaded transmission between the threaded rod and the mounting block drives the resistance block to closely contact the outer wall of the bearing to achieve secondary fixed clamping of the bearing, so that more specifications of bearings can be clamped, which is flexible.

[0019] 2. The end cover is provided so as to facilitate disassembly and assembly by utilizing the interlocking between the connecting angle piece and the installation groove, and at the same time, the characteristics of the sealing ring are utilized to improve the firmness and sealing of the end cover installation.

The mounting block 6 is penetrated by a threaded rod 8 in the vertical direction of the center of the plate body 1. The threaded rod 8 is threadedly connected to the mounting block 6. A handle 7 is welded to one end of the threaded rod 8 away from the center of the plate body 1. The other end of the threaded rod 8 is rotatably connected to the interference block 9. One end of the slide rod 10 is fixedly connected to the interference block 9, and the other end of the slide rod 10 is fixed with a limiting plate 11. A plurality of positioning holes 102 are evenly opened on the left and right sides of the slide groove 101 at the top of the plate body 1, and a screw is vertically penetrated in the positioning hole 102. Bolt 12, a nut 5 is threadedly connected to the bolt 12, and a limit block 4 is sleeved on the bolt 12. The limit block 4 is fixed on the left and right sides of the slider 3. In this embodiment, the plate body 1 is made of flame-retardant and corrosion-resistant stainless steel. The positioning hole 102 for installing the bolt 12 is selected according to the outer diameter specification of the bearing. The bolt 12 passes through the corresponding positioning hole 102 from top to bottom, and the nut 5 is turned into the limit block 4 from the bottom of the plate body 1 to fix the limit block 4, thereby realizing the positioning of the slider 4 and the mounting block 6. The interference block 9 moves with the mounting block 6 through the threaded rod 8. The threaded rod 8 is rotated, and the threaded rod 8 and the mounting block 6 are threadedly driven to make the interference block 9 close to the bearing, and the six interference blocks 9 tightly clamp the bearing to realize the fixed installation of the bearing.

[0028] The material of the abutment block 9 is silicone rubber. In this embodiment, the abutment block 9 made of silicone rubber has a stronger friction force when contacting the outer surface of the bearing, thereby improving the clamping and fixing performance.

[0029] A concave edge 104 is provided on the plate body 1, and an end cover 2 is provided on the concave edge 104. A sealing ring 201 is fixed to the inner wall of the end cover 2, and the sealing ring 201 contacts the concave edge 104. In this embodiment, the circular hole in the center of the end cover 2 passes through the motor output shaft, and the sealing ring 201 contacts the concave edge 104 on the plate body 1, so that the end cover 2 fits with the concave edge 104, avoiding protrusion and causing ineffective occupation of space, thereby improving sealing.

[0030] Three connecting angle pieces 202 are evenly fixed on the bottom of the end cover 2, and three installation grooves 103 are opened on the top of the plate body 1.

The threaded rod 8 is rotated, and the threaded rod 8 and the mounting block 6 are driven by the thread to make the interference block 9 close to the bearing. During the movement of the mounting block 6 with the threaded rod 8, the slide rod 10 plays a limiting role. It is used to prevent the mounting block 6 from rotating with the threaded rod 8, and the six interference blocks 9 tightly clamp the bearing to achieve fixed installation of the bearing. When installing the end cover 2, align the connecting angle piece 202 with the mounting groove 103 and press it down. When the connecting angle piece 202 is pressed to the bottom of the mounting groove 103, rotate the end cover 2 clockwise.
