Problems solved by technology

But the vertical vibrating and oscillating vibrating road rollers provided by the above-mentioned prior art are difficult to enter the application stage. There is a defect in the synchronous drive mechanism of two eccentric shafts installed in parallel
The two eccentric shafts installed in parallel in the oscillating vibrating wheel driven by the synchronous toothed belt, due to the harsh working conditions of the road roller, the working reliability and service life of the synchronous toothed belt are low; while the vertical vibrating wheel installed in parallel The synchronous drive of two eccentric shafts, due to the radial clearance of the vibrating bearing and the deflection changes during the rotation of the eccentric shafts, the transmission center distance of the two synchronous gears installed on the two eccentric shafts changes periodically during rotation , resulting in short service life of the two synchronous gears or even failure to operate normally

Embodiment Construction

[0031] First, a brief introduction to the prior art is made (see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 ). Typical structural schematic diagram ( figure 1 and figure 2 ), the travel motor 1 is installed on the frame 17, the travel motor 1 is connected with the vibrating wheel body 3 through the shock absorber 2, and the vibration output bearing 15 is assembled on the two ends of the vibration exciter housing 4, and the vibration output bearing 15 is installed in the vibration output bearing seat 16, and the vibration output bearing seat 16 is assembled on the two ends of the inner hole of the vibration wheel body 3. 17 connected, two eccentric shafts 5 with eccentric blocks 6 installed in parallel in the horizontal direction through the vibration bearing 7 and the vibration bearing seat 8 are relatively installed in the exciter housing 4. The so-called relative installation refers to two fixed shafts. The eccentric shaft 5 with the eccentric block 6 is...

Abstract

A synchronous driving mechanism with multiple eccentric shafts installed in parallel. A synchronous gear box is installed on the input end of multiple eccentric shafts installed in parallel on the vibration bearing seat. Synchronous gears are installed in the synchronous gear box. Each synchronous gear Corresponding to an eccentric shaft, each synchronous gear and its corresponding eccentric shaft are connected and driven by a coupling with compact structure, flexibility, and the ability to transmit torque at a constant speed. The corresponding shaft distances between the eccentric shafts are equal, and the synchronous gear is driven to drive the eccentric shafts to rotate. The invention solves the problem of the synchronous driving mechanism of multiple eccentric shafts installed in parallel.

Description

Technical field: [0001] The invention relates to a synchronous drive mechanism with multiple (two or more) eccentric shafts installed in parallel, in particular to a synchronous drive mechanism with multiple eccentric shafts installed in parallel in an exciter of a vibratory road roller, belonging to the field of road construction machinery. [0002] In the present invention, a synchronous drive mechanism with two eccentric shafts installed in parallel is taken as a typical example to illustrate a synchronous drive mechanism with multiple eccentric shafts installed in parallel. Background technique: [0003] At present, the excitation mechanisms of vibratory rollers widely used at home and abroad are exciters with a single eccentric shaft (or two eccentric shafts connected in series on one axis). The centrifugal force generated when the eccentric mass rotates at high speed forces the vibrating wheel to vibrate in the circumferential direction, that is, "circular vibration". ...
