Description

Technical Field

[0001] The utility model relates to the technical field of motor shaft protection devices, in particular to a bearing protection device for motor transportation. Background Art

[0002] The motor bearing is a special bearing used in electric motors or motors. It is a part that supports the shaft, guides the rotation of the shaft, and bears the idling parts on the shaft. There are many types of motor bearings, which help reduce friction and energy loss. In addition, motor bearings also include sliding bearings, spherical bearings and oil-containing bearings. These bearings are designed to improve the efficiency and performance of the motor while ensuring the smooth operation of the motor.

[0003] At present, most of the existing motor bearing protection devices have a relatively simple structure and can only clamp and position the two sides of the motor. Due to the different bearing sizes of the motors to be produced, most of the existing protection devices can only adapt to and position the bearings of the currently required processing size. It may be necessary for personnel to choose multiple types of protection devices to adapt to bearings of different sizes, which increases the cost of use and reduces the practicality of the device. Therefore, we propose a bearing protection device for motor transportation to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a bearing protection device for motor transportation, which solves the problem that most of the existing protection devices in the prior art can only adapt to and position bearings of the currently required processing size, and personnel are required to select multiple models of protection devices to adapt to bearings of different sizes, which increases the cost of use and reduces the practicality of the device.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Reference Figure 1-5A bearing protection device for motor transportation comprises a mounting shell 1, a limiting groove is provided on one side of the mounting shell 1, two first clamping seats 8 are symmetrically arranged on one side of the mounting shell 1, a second clamping seat 9 is provided above the two first clamping seats 8, a threaded hole is provided on one side of the bottom of the two second clamping seats 9, and a slot is provided on the other side of the bottom of the two second clamping seats 9, a bolt 10 is provided on one side of the bottom of the two first clamping seats 8, and the outer ends of the upper ends of the bolts 10 penetrate the adjacent first clamping seats 8 and are threadedly connected to the adjacent threaded holes, a limiting rod 11 adapted to the slot is fixedly connected to one side of the top of the first clamping seat 8, and the interior of the mounting shell 1 is provided with a limiting rod 11 adapted to the slot, and the interior of the mounting shell 1 is provided with a limiting rod 11 adapted to the slot. The clamping assembly is connected to the holding seat 8. Specifically, the personnel can drive the two first clamping seats 8 and the two second clamping seats 9 to move closer to each other and firmly clamp and position the two sides of the bearing. The personnel can rotate the bolt 10 and limit the second clamping seat 9 through the limit rod 11, so as to extend the distance between the first clamping seat 8 and the second clamping seat 9, so as to adapt to motor bearings of different heights or widths, thereby effectively adapting to motor bearings of different diameters. There is no need for personnel to choose multiple types of protective devices to adapt to bearings of different sizes, thereby reducing the cost of use and improving the practicality of the protective device.

[0025] Furthermore, the clamping assembly includes a bidirectional screw rod 3 arranged in the mounting shell 1, and both ends of the bidirectional screw rod 3 are rotatably connected to the inner walls of both sides of the mounting shell 1, and both ends of the outside of the bidirectional screw rod 3 are sleeved with screw sleeves 7, and one side of the outer ring of the screw sleeve 7 is fixedly connected with a limit block 6 adapted to the limit groove, and the side of the limit block 6 away from the screw sleeve 7 is fixedly connected to the outer wall of one side of the adjacent first clamping seat 8. Specifically, through the setting of the limit block 6, the limit block 6 can limit the screw sleeve 7 through the limit groove to prevent the screw sleeve 7 from rotating with the bidirectional screw rod 3, and at the same time, it is convenient to provide a stable supporting and fixing force between the screw sleeve 7 and the first clamping seat 8, so that the screw sleeve 7 can more stably drive the first clamping seat 8 to move when it moves.

[0026] Furthermore, the clamping assembly also includes a main bevel gear 4 arranged in the mounting shell 1, one side of the main bevel gear 4 is connected to the secondary bevel gear 5 through a tooth meshing connection, the interior of the secondary bevel gear 5 is socketed with the middle part of the outer side of the bidirectional screw rod 3, and the top of the main bevel gear 4 is fixedly installed with a turning handle 2 through a connecting rod penetrating the top of the mounting shell 1, and the outside of the connecting rod is rotatably connected to the top of the mounting shell 1 through a shaft sleeve. Specifically, through the setting of the main bevel gear 4, personnel can rotate by holding the turning handle 2 and drive the main bevel gear 4 to rotate through the connecting rod, and drive the secondary bevel gear 5 to drive the bidirectional screw rod 3 to rotate through the tooth, thereby causing the two screw sleeves 7 to produce a lateral displacement close to each other, and drive the first clamping seat 8 to move through the limit block 6, and then drive the second clamping seat 9 to move through the adjacent bolts 10 and the limit rod 11, thereby achieving the effect of adapting to bearings of different diameters and firmly clamping and positioning, without the need for personnel to select multiple types of protective devices to adapt to bearings of different sizes, reducing the cost of use and improving the practicality of the protective device.

[0027] Furthermore, the two first clamping seats 8 and the two second clamping seats 9 are both arc-shaped, and the inner arc surfaces of the first clamping seats 8 and the second clamping seats 9 are fixedly installed with protective pads 14. Specifically, through the setting of the protective pads 14, the protective pads 14 are soft, so that when the first clamping seats 8 and the second clamping seats 9 clamp and position the outside of the motor bearing, the clamping seat force is too large to cause damage to the outside of the bearing, thereby improving the protection effect of the bearing.

[0028] Furthermore, a card plate 12 is fixedly installed on the bottom of one of the first clamping seats 8, and a card block 13 is fixedly connected to the bottom of the other first clamping seat 8. A card slot matched with the card block 13 is opened on the top of the card plate 12. Specifically, through the arrangement of the card block 13 and the card plate 12, the card plate 12 can be adapted to the card block 13 through the card slot and is easy to slide, so that when the two first clamping seats 8 produce lateral displacements approaching or moving away from each other, they can provide a stable supporting force to the bottom of the motor bearing being clamped, so that the motor bearing can be clamped, positioned and protected more stably.

[0029] Furthermore, the outside of the turning handle 2 is provided with anti-skid patterns in a circular array. Specifically, the provision of the anti-skid patterns facilitates a person to hold the turning handle 2 and rotate it to achieve the effect of adjusting and clamping the outside of the motor bearing.

[0030] In summary:

[0031] By holding the turning handle 2 and rotating it, and driving the main bevel gear 4 to rotate through the connecting rod, and driving the bidirectional screw rod 3 to rotate through the locking teeth, the two screw sleeves 7 are caused to produce a lateral displacement close to each other, and the first clamping seat 8 is driven to move through the limit block 6, and then the two first clamping seats 8 and the two second clamping seats 9 are driven to produce a displacement close to each other through the bolt 10 and the limit rod 11, and the two sides of the outside of the bearing are firmly clamped, positioned and protected, and the second clamping seat 9 is caused to produce a vertical movement by holding the bolt 10 and rotating it through the limit of the limit rod 11, so as to achieve the effect of extending the distance between the first clamping seat 8 and the second clamping seat 9, so as to facilitate the adaptation of motor bearings of different heights or widths, thereby achieving the effect of adapting to bearings of different diameters and firmly clamping and positioning, and there is no need for personnel to select multiple types of protective devices to adapt to bearings of different sizes, thereby reducing the use cost and improving the practicality of the protective device.
