Description

Technical Field

[0001] The invention relates to the technical field of bearing installation, in particular to a full-suspension locomotive drive bearing press-fitting device. Background Art

[0002] The bearing can support the mechanical rotating body, and the steel balls between the inner and outer rings provide rolling support, thereby reducing the friction coefficient of the mechanical rotating body during movement and ensuring its rotation accuracy. The design structure of the railway traction locomotive with a full suspension structure is to reduce the unsprung weight of the locomotive, meet the high-speed and heavy-load requirements of the railway, and improve the reliability of the locomotive operation. The installed drive bearing is an indispensable key component in mechanical transmission. In the prior art, in order to reduce the labor intensity of the drive bearing during press-fitting and improve work efficiency, a hydraulic cylinder is usually used to drive the press-fitting structure to directly press the drive bearing into the mounting hole of the traction gear. The outer ring of the drive bearing and the mounting hole of the traction gear are in an interference fit, so a certain amount of pressure needs to be applied to complete the press-fitting operation. In order to ensure that the press-fitting can be accurately aligned, a mechanical component is used to align the center of the drive bearing before press-fitting, and then the hydraulic cylinder presses the drive bearing downward. The defect is that if the mechanical parts are loosened during press-fitting (i.e. the bearing is displaced relative to the mechanical parts under the thrust of the hydraulic cylinder), the driving bearing may be easily offset due to the vibration of the hydraulic cylinder; if they are not loosened, the outer ring of the driving bearing may be roughened due to the pressure of the mechanical parts.

[0007] Optionally, a groove for accommodating the traction gear is provided on the base.

[0008] Optionally, the first driving unit and the second driving unit are hydraulic rod 1 and hydraulic rod 2 respectively.

[0009] Optionally, the reset assembly includes a fixed block, a movable block and an arc-shaped guide column, the fixed block is fixed to the outer side surface of the fixed frame, the movable block is fixed to the central axis of the clamping cam 1, the arc-shaped guide column is concentric with the central axis, a spring 2 is sleeved on the guide column, one end of the guide column is fixed to the movable block, and the other end passes through the fixed block, and the guide column is slidably connected to the fixed block.

[0011] Optionally, the second clamping cam and the first clamping cam are arranged alternately.

[0012] The advantages and positive effects of the present invention are:

[0013] 1. This device has been optimized to achieve the precise positioning function of press-fitting and synchronously adjusting at the same time. The driving bearing is clamped by three sets of clamping mechanisms installed on the outer surface of the mounting ring. First, the telescopic column is used to drive the telescopic column and the clamping cam to roll with the driving bearing, and the pressure is used to shrink toward the inside of the sealing cylinder, compressing the sealing cylinder to obtain the rebound force. At this time, the sealing column is driven upward by the spring three, and the kerosene inside the sealing cylinder flows back through the connecting cavity under the push of the telescopic column. When the clamping cam rotates to one side of the plane and abuts against the driving bearing, sufficient friction is generated and The driving bearing is supported and flexibly clamped for the first time. The limiting column is abutted against the base to make the supporting column move downward relative to the clamping mechanism, and drive the sealing column downward into the middle of the connecting cavity to block the kerosene reflux path in the inner cavity of the sealing cylinder. At this time, the clamping force of the clamping cam on the driving bearing becomes rigid. As the driving bearing is pressed downward by the pressure plate and displaced, the clamping cam is driven to rotate, which not only realizes the positioning function of the driving bearing, but also avoids the possible burring phenomenon on the outside of the driving bearing through rolling friction, thereby effectively protecting the driving bearing.

[0014] 2. The device is also provided with a mounting ring, a motor, a rotating shaft, an outer gear ring, gears and a clamping cam 2 to realize the first effective clamping and positioning of the driving bearing. A group of outer gear rings and multiple groups of rotating shafts are rotatably installed in the inner cavity of the mounting ring. The multiple groups of rotating shafts are meshed through the gears installed on their outer surfaces to realize the synchronous rotation of the three groups of rotating shafts. Driven by the motor, the three groups of clamping cams 2 can realize synchronous rotation through the transmission of the three groups of rotating shafts, so that one side of the plane of the clamping cam 2 rolls against the outer surface of the driving bearing, which greatly improves the centering accuracy of the driving bearing.

[0015] 3. The reset assembly is connected to the clamping cam 1. When the driving bearing abuts against the clamping cam 1 and drives the clamping cam 1 to rotate, the clamping cam 1 will drive the guide column to rotate and pass through the fixed block, and at the same time compress the spring 2 to generate a rotational elastic force. The direction of the rotational elastic force is opposite to the rotation direction of the clamping cam 1. When the driving bearing moves downward, it will provide rotational resistance to the clamping cam 1 and act on the driving bearing. When the clamping cam 1 rotates to one side of its plane and abuts against the driving bearing, the rotational elastic force generated by the spring 2 is just perpendicular to the surface of the driving bearing and increases the friction between the clamping cam 1 and the driving bearing, making the clamping of the driving bearing more stable.

[0029] Three groups of clamping mechanisms 9 and mounting blocks 10 corresponding to the clamping mechanisms 9 are evenly distributed on the outer side of the mounting ring 11 around its axis. The mounting blocks 10 are fixed to the outer side of the mounting ring 11. The movable plate 5 has support columns 6 corresponding to the mounting blocks 10. The support columns 6 pass through the mounting blocks 10. The mounting blocks 10 are slidably connected to the support columns 6. The lower ends of the support columns 6 have limit blocks for limiting the position of the support columns 6. The limit blocks ensure that the mounting blocks 10 are suspended on the support columns 6.

[0030] The clamping mechanism 9 includes a mounting seat 91, a sealing cylinder 92, a telescopic column 94, a fixing frame 95, a clamping cam 96, a sealing block 912, a placing cylinder 913 and a sealing column 914. The mounting seat 91 is fixed to the side of the mounting ring 11, the sealing cylinder 92 is fixed to the outer surface of the mounting seat 91, the open end of the sealing cylinder 92 faces the bottom of the mounting ring 11, one end of the telescopic column 94 extends from the open end of the sealing cylinder 92 into the sealing cylinder 92, the cross section of the telescopic column 94 is "T"-shaped, and the sealing cylinder 92 has a spring 93, and the two ends of the spring 93 can be The two ends of the telescopic column 94 are in contact with the other end of the sealing cylinder 92 and one end of the telescopic column 94, and the end of the telescopic column 94 located outside the sealing cylinder 92 is connected to the fixing frame 95. The clamping cam 96 is located on the fixing frame 95. Both sides of the fixing frame 95 have a reset assembly for the clamping cam 96. The reset assembly includes a fixed block 97, a moving block 98 and an arc-shaped guide column 99. The fixed block 97 is fixed to the outer surface of the fixing frame 95, and the moving block 98 is fixed to the central axis of the clamping cam 96. The arc-shaped guide column 99 is concentric with the central axis. A spring 910 is provided, one end of the guide column 99 is fixed to the moving block 98, and the other end passes through the fixed block 97, the guide column 99 is slidably connected to the fixed block 97, the sealing block 912 is fixed to the top of the sealing cylinder 92, the placement cylinder 913 is fixed to the top of the sealing block 912, and the sealing block 912 has a connecting cavity 916, both ends of the connecting cavity 916 are connected to the inside of the sealing cylinder 92, and the two ends of the connecting cavity 916 are respectively close to the two ends of the sealing cylinder 92, the placement cylinder 913 is connected to the connecting cavity 916, and the sealing column 914 is located in the placement cylinder 913. The outer diameter of the lower part of the column 914 is larger than the outer diameter of the upper part of the sealing column. The top of the placing cylinder 913 has a hole that allows the upper end of the sealing column 914 to extend out. The sealing column 914 is slidably connected to the placing cylinder 913. A spring three 915 is sleeved on the upper part of the sealing column 914. The two ends of the spring three 915 can respectively contact the top of the placing cylinder 913 and the lower part of the sealing column 914. The lower end of the sealing column 914 can penetrate into the connecting cavity 916. The bottom of the sealing cylinder 92 has a limiting column 911. The sealing cylinder 92 is filled with kerosene, and kerosene can flow between the connecting cavity 916 and the sealing cylinder 92.

[0031] The base 1 is provided with a groove for placing the traction gear, the inner part of the mounting ring 11 is rotatably mounted with an outer gear ring 14, and three clamping cams 16 are evenly distributed around the axis of the mounting ring 11 below. The clamping cam 16 has a rotating shaft 13, and the rotating shaft 13 has a gear 15, which extends into the mounting ring 11, and the gear 15 meshes with the teeth on the inner side of the outer gear ring 14. One of the rotating shafts 13 is connected to a motor 12, and the three groups of rotating shafts 13 are driven by the motor 12 to realize synchronous rotation, so that the plane side of the clamping cam 16 rolls against the outer surface of the driving bearing, which greatly improves the centering accuracy of the driving bearing. The clamping cam 16 and the clamping cam 1 96 clamp the driving bearing together.

[0032] The device has been optimized to achieve the precise positioning function of press-fitting and synchronously adjusting at the same time. The driving bearing is clamped by three groups of clamping mechanisms 9 installed on the outer surface of the mounting ring 11. First, the telescopic column 94 is used to drive the telescopic column 94 and the clamping cam 96 to roll with the driving bearing, and the pressure is used to shrink toward the inside of the sealing cylinder 92 to compress the sealing cylinder 92 to obtain the rebound force. At this time, the sealing column 914 is driven upward by the spring 915, and the kerosene inside the sealing cylinder 92 flows back through the connecting cavity 916 under the push of the telescopic column 94. When the clamping cam 96 rotates to the side plane thereof to abut against the driving bearing, sufficient The friction force supports the driving bearing and performs the first flexible clamping on the driving bearing. The limiting column 911 is abutted against the base 1 to make the support column 6 move downward relative to the clamping mechanism 9, and drive the sealing column 914 downward into the middle of the connecting cavity 916 to block the kerosene reflux path in the inner cavity of the sealing cylinder 92. At this time, the clamping force of the clamping cam 96 on the driving bearing becomes rigid. As the driving bearing is pressed downward by the pressure plate 8 and displaced, the clamping cam 96 is driven to rotate, which not only realizes the positioning function of the driving bearing, but also avoids the possible hair pulling phenomenon on the outside of the driving bearing through rolling friction, thereby effectively protecting the driving bearing.

[0033] The driving gear is placed from the upper part of the mounting ring 11 and performs the first positioning sliding through the inner ring surface of the mounting ring 11. The reset components are symmetrically distributed at both ends of the central axis of the clamping cam 96. When the driving bearing abuts against the clamping cam 96 and drives the clamping cam 96 to rotate, the clamping cam 96 will drive the guide column 99 to rotate and pass through the fixed block 97, and at the same time compress the spring 2 910 to generate a rotational elastic force. The direction of the rotational elastic force is opposite to the rotation direction of the clamping cam 96. When the driving bearing moves downward, it will provide rotational resistance to the clamping cam 96 and act on the driving bearing. When the clamping cam 96 rotates to one side of its plane and abuts against the driving bearing, the rotational elastic force generated by the spring 2 910 is just perpendicular to the surface of the driving bearing and increases the friction between the clamping cam 96 and the driving bearing, making the clamping of the driving bearing more stable.

[0034] The flat part of the clamping cam 96 abuts against the outer surface of the driving bearing, and the clamping cam 96 can rotate downward around its axis and compress the spring 2 910; the flat side part of the clamping cam 96 abuts against the outer surface of the driving bearing, and its contact surface is a line, which greatly increases the contact area and helps to improve the friction. The cross-sectional shape of the telescopic column 94 is "T" shaped, and the kerosene is sealed and isolated from both sides of the inner cavity of the sealing cylinder 92 by the other end of the telescopic column 94, and the kerosene can flow back through the connecting cavity 916;

[0035] like Figure 3As shown, the other end of the telescopic column 94 divides the inner cavity of the sealing cylinder 92 into two parts. When it moves, it will push the kerosene therein to flow back and forth. When the connecting cavity 916 is connected, the telescopic column 94 can move freely. When the connecting cavity 916 is blocked by the sealing column 914, the incompressible property of kerosene will fix the telescopic column 94, so as to provide a rigid clamping force for the drive bearing during press installation.

[0036] The limit block design at the bottom of the support column 6 is responsible for supporting the mounting block 10, the mounting ring 11 and the clamping mechanism 9 as a whole. When the limit column 911 moves to the lowest point, it provides support for the mounting block 10, the mounting ring 11 and the clamping mechanism 9. At this time, the support column 6 continues to move downward and presses the sealing column 914 to block the connecting cavity 916, fix the position of the telescopic column 94, and cooperate with the clamping cam 96 to provide rigid clamping for the drive bearing.

[0037] When the bottom of the limiting column 911 abuts against the base 1, the bottom end of the supporting column 6 abuts against the top end of the sealing column 914, and drives the sealing column 914 downward into the middle of the inner wall of the connecting cavity 916, so that the middle of the connecting cavity 916 is blocked;

[0038] The sealing column 914 is used to seal the connecting cavity 916. When the driving bearing enters between the clamping cams 96, kerosene can flow freely through the connecting cavity 916. When the sealing column 914 seals the connecting cavity 916, the kerosene no longer flows. At this time, the telescopic column 94 is directly fixed.

[0039] The outer surface of the clamping cam 16 abuts against the driving bearing, and the protruding side of the clamping cam 16 is away from the outer surface of the driving bearing;

[0040] When one side of the plane of the clamping cam 16 is away from the driving bearing, it does not exert force on the bearing. When the driving bearing is press-fitted, the clamping cam 16 will not scratch the outer surface of the driving bearing.

[0041] Working principle:

[0042] When the device is working:

[0043] First, place the traction gear in the groove at the top of the base 1, and put the driving gear in from the top of the mounting ring 11, so that it moves downward through the inner wall of the mounting ring 11 and contacts the clamping mechanism 9. The driving gear falls on the outer surface of the clamping cam 96 and drives the clamping cam 96 to rotate downward. The reset assembly starts to work, driving the moving block 98 and the guide column 99 to rotate around the axis of the clamping cam 96, and compressing the spring 910 to generate a rotational elastic force. At the same time, the fixing frame 95 and the clamping cam 96 are stressed and contracted outward, driving the telescopic column 94 to compress the spring 93, and the kerosene in the inner cavity of the sealing cylinder 92 flows back through the connecting cavity 916. When the clamping cam 96 rotates until its one side plane just fits and abuts against the outer surface of the driving bearing, it generates friction with the driving bearing and offsets the gravity.

[0044] Then, the motor 12 is started, and the shaft 13 and the gear 15 are driven to rotate. The gear 15 drives the outer gear ring 14 to rotate, and transmits the power to other gears 15 and the shaft 13 synchronously, so that the multiple groups of clamping cams 16 rotate synchronously at the same angle. Figure 5 As shown, the raised plane of the clamping cam 16 abuts against the outer surface of the driving bearing after rotation, and applies pressure to the driving bearing as the motor 12 is driven, and the torque of the motor 12 is set to position the axis of the driving bearing to the same position as the traction gear;

[0045] Then, the hydraulic rod 1 4 is started and drives the support column 6, the mounting block 10 and the clamping mechanism 9 to move downward. When the bottom of the limit column 911 abuts against the base 1, the clamping mechanism 9 and the mounting ring 11 stop moving downward as a whole. At this time, the support column 6 used to support the mounting block 10 will continue to move and push the sealing column 914 downward to move, stretching the spring 3 915. The sealing column 914 is blocked in the middle of the connecting cavity 916, preventing the two streams of kerosene in the inner cavity of the sealing cylinder 92 from being sealed and isolated by the sealing cylinder 92. At this time, the telescopic column 94 cannot move, and the motor 12 is started to rotate and reset, so that the clamping cam 2 16 no longer applies pressure to the outer surface of the driving bearing.

[0046] Finally, the hydraulic rod 2 7 is started, and the pressure plate 8 is driven downward through the inner ring of the mounting ring 11, and the drive bearing is pressed, as shown in FIG. Figure 2 As shown, the driving bearing moves downward relative to the clamping cam 96, but the two are in rolling friction. When the driving bearing moves downward, the clamping cam 96 will roll along with it, and the telescopic column 94 and the fixing frame 95 provide rigid clamping pressure for the bearing. The bearing is pressed into the mounting hole of the traction gear by the pressure plate 8.

[0047] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
