Description

TECHNICAL FIELD

[0001] The utility model relates to drive motor connection technical field especially relates to a road roller drive motor and drive wheel side plate connecting structure. BACKGROUND

[0002] The road roller is a kind of heavy machinery equipment for road and site construction, mainly used for compacting soil, gravel and asphalt concrete and other materials to improve the bearing capacity and durability of road and site. Road roller makes the gap between materials reduce and the friction between particles increase through the compaction and vibration of heavy objects, thereby improving the density and strength of materials. Road roller is mainly composed of chassis, road roller, vibration system and drive system. The chassis is the supporting structure of the whole road roller, which can bear the weight and compaction force of the road roller. The road roller is the main working part of the road roller, which compacts materials through weight and vibration. The vibration system can make the road roller vibrate at high frequency, further improving the density of materials. The drive system provides power to make the road roller move and work. In actual work, the road roller is usually divided into static pressure and vibration two working modes. Static pressure refers to the compaction of materials by the weight of the road roller, which is suitable for the compaction of soil and gravel materials. Vibration is the high-frequency vibration generated by the vibration system, which can further improve the density of materials, suitable for the compaction of asphalt concrete materials.

[0003] During the working process of the road roller, the drive motor often needs to bear a large load due to its special working environment and operation requirements. When the shaft side static force of the drive motor is large, it will have a serious impact on each part of the motor. First, the bearing of the motor needs to bear larger radial and axial forces, which will accelerate the wear of the bearing and reduce the service life of the bearing. With the passage of time, the severely worn bearing will have problems such as increased clearance, increased noise and even jamming, thereby affecting the normal operation of the motor. Secondly, the shaft side static force will also cause the bending deformation of the motor shaft, which will not only affect the rotation accuracy of the shaft, but also cause problems in the cooperation between the shaft and other parts, further aggravating wear and failure. Since the shaft side static force of the drive motor is large, the motor needs to consume more energy to overcome these additional forces during operation, which not only increases energy consumption, but also increases the temperature of the motor. High temperature will accelerate the aging and damage of internal parts of the motor, further shortening the service life of the motor. At the same time, frequent maintenance will not only increase maintenance cost, but also increase the downtime of the road roller, affecting the progress and efficiency of construction, therefore, a road roller drive motor and drive wheel side plate connecting structure is proposed to solve the above problems. SUMMARY

[0004] In order to make up for the above shortcomings, the utility model provides a road roller drive motor and drive wheel side plate connecting structure, aims at improving the problem of the higher failure rate of the service life of the motor caused by the larger static force on the drive motor shaft side in part of the prior art road roller.
