Description

Technical Field

[0001] The invention relates to a vibrating wheel, in particular to a vibrating wheel for a road roller, and belongs to the technical field of engineering machinery. Background Art

[0002] As the core component of the vibratory roller, the vibratory wheel directly affects the working performance, maintenance performance and service life of the roller. Its core role is mainly reflected in three aspects: criticality - the vibratory wheel is the working device of the vibratory roller; complexity - the vibratory bearing bears huge alternating loads, but due to structural limitations, the lubrication and heat dissipation conditions are very poor; uncertainty - the internal lubrication condition is invisible and intangible, and problems are prone to occur and cannot be repaired in time when problems occur.

[0003] There are two pairs of vibrators in the vibrating wheel of a traditional roller. The lubricating oil in the vibrator is used to lubricate the vibrating bearing. To prevent the lubricating oil from penetrating into the inside of the vibrating wheel, a sealing ring is provided on the inner bearing cover during design. However, the lubricating oil still leaks. The main reasons are as follows: when assembling the eccentric shaft, the sealing ring of the vibrating bearing and the inner bearing cover are first assembled as a whole and installed in the vibrating wheel body, and then the eccentric block is assembled. During assembly, it is impossible to see whether the sealing ring inside is damaged or not, and the dirt in the vibrating wheel body is difficult to remove. It will be brought to the sealing ring during operation, exacerbating its damage and causing the lubricating oil to leak. In addition, simple manufacturing problems can also cause the lubricating oil to leak at the vibrator sealing ring.

[0004] The existing Chinese public patent CN206570655U is an intelligent steering vibratory roller and its vibratory wheel, which discloses a technical solution including "a first annular plate 22 and a second annular plate 4 are arranged in the vibratory wheel body 1, and the vibrator 3 is arranged between the first annular plate 22 and the second annular plate 4". The disclosed technical solution has the problem that during assembly, the internal structure cannot be observed due to the obstruction of the annular plate, and structural problems cannot be discovered and repaired in time. During use, due to the limitation of the annular plate, the interior cannot be cleaned in time, and damage to the structural parts cannot be discovered in time, which has a great impact on the safe operation of the roller and also has a negative impact on the service life of the vibratory wheel of the roller. Summary of the invention

[0005] Purpose of the invention: In view of the deficiencies in the prior art, the present invention provides a vibratory wheel for a roller. By optimizing the structure of the vibratory wheel for a roller, the exciter in the vibratory wheel for a roller is simplified from the traditional two paired exciters to an independent exciter. The parts are easy to install and disassemble, and damage can be quickly discovered and replaced, thereby greatly improving the operating efficiency of the vibratory roller.

[0006] Technical solution: A vibrating wheel for a road roller comprises a wheel body, a sealing plate, an exciting chamber, a bearing seat and an exciter, wherein the outer ring of the sealing plate matches the inner ring of the wheel body, the sealing plate is arranged inside the wheel body and fixedly connected to the wheel body, the exciting chamber is axially mounted on the sealing plate provided with an exciting chamber mounting hole, and further comprises a left connecting support and a right connecting support mounted at the center positions on both sides of the wheel body, the right side of the right connecting support is fixedly connected to a frame assembly, the right side of the exciter is splined to a vibration motor assembly, the right side of the bearing seat is connected to a traveling assembly rotatably connected to the exciting chamber, the traveling assembly comprises a traveling bearing seat rotatably connected to the exciting chamber and a traveling bearing seat fixedly connected to a first shock absorbing assembly,

[0010] The present invention optimizes the structure of the roller vibrating wheel, simplifies the vibrator in the roller vibrating wheel from the traditional two paired vibrators to an independent vibrator, and changes the bearing seat mounting hole and mounting surface from the traditional double-sided processing to single-sided processing. Single-sided processing does not require the wheel body to be turned on the machine tool, and the coaxiality of the bearing seat mounting hole and the inner ring of the wheel body can be extremely well controlled, thereby improving the processing accuracy and processing efficiency; at the same time, the assembly method is also optimized, the number of vibrators is changed from two to one, and the assembly is changed from assembling from both sides of the vibrating wheel to completing the assembly from one side of the vibrating wheel, and the single-sided assembly improves the assembly efficiency. In addition, since the improved vibrating wheel has only one vibrator, the parts are easy to install and disassemble, and damage can be quickly discovered and replaced, which greatly improves the operating efficiency of the vibrating roller.

[0011] Preferably, in order to improve the rigidity of the middle area of ​​the wheel rim, the welding supports and ribs are distributed in an array along the circumferential direction of the sealing plate, and the welding supports and ribs are arranged in an alternating manner.

[0012] Welded supports and ribs are evenly distributed on the left and right surfaces of the sealing plate, which are welded to the inner side of the wheel body and the sealing plate, respectively, to improve the rigidity of the middle area of ​​the wheel rim, increase the speed at which the excitation force of the excitation chamber is transmitted to both ends of the wheel body, and improve the uniformity of the compaction force on the outer surface of the vibration wheel. The rib plate and the welded supports are located on different sides of the sealing plate, and the rib plate and the welded supports are staggered, which helps to improve the support capacity of the wheel body.

[0013] Preferably, in order to achieve lateral uniformity of amplitude, the sealing plate is arranged in the wheel body near the left connecting support, and the installation position is determined according to the calculation result of the four centers of the vibration wheel in one.

[0014] Since the components at both ends of the vibration wheel are assembled asymmetrically, there is a difference in the mass distribution at both ends of the vibration wheel. This arrangement can solve the problem of lateral uniformity deviation of the amplitude of the same vibration wheel.

[0017] Preferably, in order to achieve vibration isolation between the left and right connecting supports and the excitation chamber, the right connecting support and the exciter are connected via a first shock absorbing assembly, and the left connecting plate and the welding support are connected via a second shock absorbing assembly.

[0018] In order to prevent the left and right connecting supports from being affected by the vibration of the exciter, shock absorbing components are installed on both sides to isolate the vibration.

[0019] Preferably, in order to achieve efficient vibration isolation and reduction, the first shock absorbing assembly includes a right connecting plate fixedly connected to the traveling bearing seat and a right shock absorber fixedly connected between the right connecting plate and the right connecting support; the second shock absorbing assembly includes a left shock absorber arranged on each welding support.

[0020] Preferably, in order to achieve stable installation of the bearing seat, a bearing seat mounting stop is provided on the right side of the sealing plate and is surrounded by the circumferential direction of the excitation chamber mounting hole. A bearing seat mounting surface is provided on the side of the bearing seat mounting stop close to the right connecting plate. A bearing seat mounting hole is provided on the bearing seat mounting surface. The bearing seat is fixed to the sealing plate by fastening bolts that penetrate the bearing seat mounting hole.

[0021] The bearing seat mounting hole and mounting surface are changed from traditional double-sided processing to single-sided processing. Single-sided processing does not require the wheel body to be turned on the machine tool. The coaxiality of the bearing seat mounting hole and the inner ring of the wheel rim can be extremely controlled, which improves the processing accuracy and efficiency.

[0022] Beneficial effects: The present invention optimizes the structure of the roller vibrating wheel, simplifies the vibrator in the roller vibrating wheel from the traditional two paired vibrators to an independent vibrator, and changes the bearing seat mounting hole and mounting surface from the traditional double-sided processing to single-sided processing.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0035] The sealing plate 2 is provided as one, a welding support 22 is provided on one side of the sealing plate 2, and a rib plate 23 is provided on the other side, and the welding support 22 and the rib plate 23 are both fixedly connected to the sealing plate 2 and the inner side of the wheel body 1;

[0036] The excitation chamber 3 includes a bearing seat 31 mounted on the sealing plate 2 and an exciter 32 mounted in the bearing seat 31, and the travel bearing is rotatably connected to the bearing seat 31;

[0037] The welding support 22 is connected to a left connecting plate 6 at a side away from the vibration exciter 32 , and the left connecting plate 6 is used to connect a reducer.

[0038] The present invention optimizes the structure of the roller vibrating wheel, simplifies the vibrator 32 in the roller vibrating wheel from the traditional two pairs of vibrators 32 to an independent vibrator 32, and changes the bearing seat mounting hole 25 and the mounting surface from the traditional double-sided processing to single-sided processing. Single-sided processing does not require the wheel body 1 to be turned on the machine tool, and the coaxiality of the bearing seat mounting hole 25 and the inner ring of the wheel body 1 can be extremely well controlled, thereby improving the processing accuracy and processing efficiency; at the same time, the assembly method is also optimized, the number of vibrators 32 is changed from two to one, and the assembly is changed from assembling from both sides of the vibrating wheel to completing the assembly from one side of the vibrating wheel, and the single-sided assembly improves the assembly efficiency. In addition, since the improved vibrating wheel has only one vibrator 32, the parts are easy to install and disassemble, and damage can be quickly discovered and replaced, which greatly improves the operating efficiency of the vibrating roller.

[0039] like Figure 3 and 4 As shown, in order to improve the rigidity of the middle area of ​​the wheel rim, the welding supports 22 and the ribs 23 are distributed in an array along the circumferential direction of the sealing plate 2, and the welding supports 22 and the ribs 23 are arranged in an alternating manner.

[0040] The welded supports 22 and ribs 23 are evenly distributed on the left and right surfaces of the sealing plate 2, which are respectively welded to the inner side of the wheel body 1 and the sealing plate 2, thereby improving the rigidity of the middle area of ​​the wheel rim, and increasing the speed at which the exciting force of the exciting chamber 3 is transmitted to the two ends of the wheel body 1, thereby improving the uniformity of the compaction force on the outer surface of the vibration wheel. The ribs 23 and the welded supports 22 are respectively located on different sides of the sealing plate 2, and the ribs 23 and the welded supports 22 are staggered, thereby assisting in improving the support capacity of the wheel body 1.

[0041] like Figure 1 As shown, in order to achieve lateral uniformity of amplitude, the sealing plate 2 is arranged in the wheel body 1 near the left connecting support 4, and the installation position is determined according to the calculation result of the four centers of the vibration wheel.

[0042] Due to the asymmetric assembly of the components at both ends of the vibration wheel, there is a difference in the mass distribution at both ends of the vibration wheel. This arrangement can solve the problem of lateral uniformity deviation of the amplitude of the same vibration wheel. The four centers of the vibration wheel are in one, which refers to the compaction width of the centroid of the inner ring of the wheel body, the center of mass of all the parametric masses of the wheel body, the center of force of the eccentric shaft excitation force, and the center of mass of the distributed mass of the vibration wheel. The four centers are in one, so that the amplitude at both ends of the vibration wheel is consistent, the road surface compaction quality is high, and the vibration energy consumption is low.

[0044] The left connecting plate 6 is used to connect the reducer, and its installation stability is very important. Therefore, a radially installed transverse plate 222 is set on the axially arranged vertical plate 221 to provide a larger installation area for the left connecting plate 6, and each transverse plate 222 is provided with a plurality of bolt mounting holes for fixing the left connecting plate 6 and the welding support 22, thereby increasing the installation stability.

[0045] like Figure 1 and 2 As shown, in order to achieve vibration isolation between the left and right connecting supports 5 and the excitation chamber 3, the right connecting support 5 and the exciter 32 are connected via a first shock absorbing assembly 7, and the left connecting plate 6 and the welding support 22 are connected via a second shock absorbing assembly 8.

[0046] In order to prevent the left and right connecting supports 5 from being affected by the vibration of the exciter 32, shock absorbing components are installed on both sides to isolate and reduce vibration.

[0047] In order to achieve efficient vibration isolation and reduction, the first shock absorbing assembly 7 includes a right connecting plate 71 fixedly connected to the traveling bearing seat and a right shock absorber 72 fixedly connected between the right connecting plate 71 and the right connecting support 5; the second shock absorbing assembly 8 includes a left shock absorber 81 arranged on each welding support 22.
