Problems solved by technology

During the use of the single-drum vibratory roller, the rotating shaft will generate a large amount of heat energy, which will cause the temperature of the rotating shaft itself to rise and cause deformation, so that the gap reserved for the rotating shaft cannot meet the deformation of the rotating shaft itself, resulting in inflexible rotation of the rotating shaft , affecting the process efficiency of the roller

Embodiment 1

[0023] like Figure 1 to Figure 3 As shown, a vibrating wheel body 3 of the present invention includes a vibrating wheel body 1 and a central shaft 2. One end of the central shaft 2 runs through the end of the vibrating wheel body 1 and rotates the other side of the central shaft 2 on the inner wall of the vibrating wheel body 1. One end is connected to the output end of the driving motor, and a supporting seat 3 is installed on the vibrating wheel body 1, and a supporting inner ring 11 and a supporting outer ring 12 are sequentially arranged on the supporting seat 3 along the axial direction of the central axis 2. A groove 17 is formed on the ring 11, and a blind hole is formed on the inner wall of the groove 17, and a roller 16 is rotated in the blind hole, and the roller 16 is in contact with the central shaft 2, and at the joint between the roller 16 and the inner wall of the groove 17 A floating sleeve 15 is installed, and a roller 16 is arranged in the floating sleeve 15...

Embodiment 2

[0025] like figure 1 As shown, in this embodiment, on the basis of Embodiment 1, a rectangular groove 4 is formed on the inner wall of the vibrating wheel body 1 corresponding to the support seat 3, and a roller 6 is rotated on the end of the rectangular groove 4. The roller 6 is in contact with the central shaft 2 , leaving a gap 5 between the end of the central shaft 2 and the bottom of the rectangular groove 4 . After the central shaft 2 works for a long time, more heat will be generated, which will cause the volume of the central shaft 2 to change after being heated. The rolling connection between the central shaft 2 and the roller 6 in the rectangular groove 4 changes the sliding friction into rolling friction. The generation of heat can be reduced, and the gap 5 left between the central shaft 2 and the bottom of the rectangular groove 4 can compensate the thermal elongation of the central shaft 2, ensuring that the central shaft 2 continues to work normally after being h...

Embodiment 3

[0027] like figure 1 and image 3As shown, in this embodiment, on the basis of Embodiment 1, a movable eccentric block 10 and two fixed eccentric blocks 7 are installed on the central shaft 2, and the movable eccentric block 10 is arranged between the two fixed eccentric blocks 7, A stop pin 8 is arranged on the fixed eccentric block 7, and the movable eccentric block 10 is rotatably arranged on the central shaft 2, and a protrusion 19 is installed on the movable eccentric block 10, and the stop pin 8 is positioned on the protrusion 19 Do circular motion on the track. When the drive motor drives the central shaft 2 to rotate clockwise, the static eccentricity of the movable eccentric block 10 and the fixed eccentric block 7 will be subtracted, thereby producing a small amplitude, that is, when the eccentric blocks reach the lowest point at the same time, under the action of centrifugal force, the entire The vibrating wheel body 1 is supported by the earth; when the central s...

Abstract

The invention discloses a vibrating drum body which comprises a vibrating drum body and a center shaft, wherein a bearing seat is arranged on the vibrating drum body; a supporting inner ring and a supporting outer ring are arranged on the bearing seat along the axial direction of the center shaft in sequence; a groove is formed in the supporting inner ring; a blind hole is formed in the inner wall of the groove; a rolling shaft is rotatably arranged in the blind hole; the rolling shaft is in contact with the center shaft; a floating casing is arranged at the joint between the rolling shaft and the inner wall of the groove; the rolling shaft is arranged in the floating casing; the floating casing is connected with the inner wall of the blind hole through a spring. According to the floating casing, the radial displacement of the rolling shaft can be realized, when the spring is compressed, the radial stress generated by the center shaft can be buffered, and when the spring returns, the rolling shaft can be reset, so that the automatic adjustment of the center shaft can be realized when the center shaft is heated to cause volume change, the bearing seat is prevented from serious damage and then the service life of the vibrating drum body is prolonged.

Description

technical field [0001] The invention relates to a vibrating road roller, in particular to a vibrating wheel body. Background technique [0002] Road roller is a kind of compaction construction machinery with special steel wheels or slick tires as the operating device. It is widely used in road engineering, airport ports, mine dams, municipal construction, etc. for compaction of earth and rock filling and road pavement materials. Its function is to increase the compactness of the working face, thereby improving the structural strength and rigidity of the working face, enhancing the anti-permeability and climate stability, reducing or eliminating subsidence, and finally achieving the purpose of improving the engineering bearing capacity, prolonging the service life and reducing maintenance costs . Because the working conditions of compaction operations vary widely, there are various types and specifications of compaction machinery, which can be simply divided into road roller...
