Abstract
The utility model relates to a driving running mechanism for a road roller. A supporting plate of a central shaft of a driving steel wheel is provided with a driving motor and a driving speed reducer, an output shaft of the driving motor is connected with an input shaft of the driving speed reducer by a key connecting sleeve barrel, and an output end of the driving speed reducer is connected with an inner hole of a shaft sleeve of a driving roller by a connecting key; an outer shaft of the shaft sleeve of the driving roller is connected with a roller frame of a vibration road roller by a rolling bearing, an integral bearing seat and a connecting bolt. An output end of the central shaft of the driving steel wheel is matched with a rolling steel barrel, and a boss plate of the rolling steel barrel is connected with the outer margin of the rolling steel barrel; the center of the output end of central shaft of the driving steel wheel is provided with an externally connecting through hole for a power line for the motor, the outer end is connected with a fixed bearing seat and the fixed bearing seat is connected with the roller frame. In the utility model, the traditional external driving motor and the driving speed reducer are arranged in the rolling steel barrel, so the structure is very compact; moreover, the defects of belt drive or sprocket drive can be overcome and the purposes of reliable operation and low cost can be reached thereby.
Description
Technical field:
The utility model belongs to engineering machinery field, is specifically related to a kind of road roller and drives walking mechanism.
Background technology
At present, the drive system used on vibratory roller great majority are a kind of hydraulic gear, and its adopts and rolls one side of steel wheel axle or both sides in driving and load onto hydraulic motor and drive, and need adorn hydraulic power unit on vibratory roller, thus complex structure, the cost height.And other adopts the machine driven system of common electric machine, gear or belt pulley, chain gear transmission, owing to outside drive motors is exposed to, be subject to the environment pollution influence, cumbersome to the protection of belt, chain gear transmission, operating reliability is relatively poor.
Summary of the invention:
The purpose of this utility model provides a kind of driving mechanism that can overcome the double-steel wheeled vibratory roller of above-mentioned shortcoming.
The technical scheme that realizes the utility model purpose is: on the support plate of its driving steel wheel central axis drive motors and drive speed reducer are housed, the output shaft of drive motors links to each other with the drive speed reducer power shaft by the key branch sleeve, the drive speed reducer output links to each other with head roll axle sleeve endoporus by connecting key, and head roll axle sleeve outer shaft links to each other with the vibratory roller frame by rolling bearing, solid housing and connecting bolt; Drive steel wheel central axis output and constitute movingly by rolling bearing in the rolling steel cylinder hub plate central boss and rolling steel cylinder, rolling steel cylinder hub plate links to each other with screw by seam with rolling steel cylinder outer rim; Driving steel wheel central axis output center has the external through hole of motor power-supply wire, and the outer end is rigidly connected by screw and fixed bearing block, and fixed bearing block is connected with bolt with frame.
Operating principle of the present utility model is: external power supply is connected with the drive motors that is installed on the central axis support plate by the centre bore of rolling steel wheel central axis, the motor output shaft that rotates drives the drive speed reducer power shaft by the key branch sleeve and rotates, output shaft by drive speed reducer drives the rotation of rolling steel cylinder axle sleeve again, also force the rolling steel cylinder to rotate thereupon, rotate with these front and back of realizing head roll, reach the purpose that the driving vibratory roller advances, retreats; And rolling steel cylinder axle sleeve outer shaft and rolling bearing with fixed bearing block that the vibratory roller frame links to each other in rotate, its driving torque is by bearing by the hold-down screw of steel wheel central axis output with the rigidly connected frame of fixed bearing block.
The present invention packs traditional cleverly outer centrally-mounted driving and drive speed reducer in the rolling steel cylinder together, reaches the purpose that drives the rolling steel cylinder.So both make structure very compact, overcome the disadvantage of belt or chain gear transmission again, thereby reached running purpose reliable, with low cost.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a shape assumption diagram of the present utility model.
Among the figure: 1. vibratory roller frame; 2. fixed bearing block; 3. hold-down screw; 4. rolling steel cylinder central axis; 5. rolling bearing; 6. rolling steel cylinder hub plate; 7. rolling steel cylinder; 8. drive motors; 9. connecting key; 10. branch sleeve; 11. connecting key; 12. drive speed reducer; 13. connecting key; 14. rolling steel cylinder axle sleeve; 15. rolling bearing; 16. solid housing.
The specific embodiment:
The vibratory roller frame 1 of present embodiment as shown in Figure 1 and Figure 2 is supported on the rolling steel cylinder central axis 4 by fixed bearing block 2 on one side, rolling steel cylinder central axis 4 and rolling bearing 5 rests are on rolling steel cylinder hub plate 6 and rolling steel cylinder 7, and the another side of vibratory roller frame 1 is supported on the rolling steel cylinder axle sleeve 14 by solid housing 16, rolling bearing 15; The external power lead passes the centre bore of rolling steel cylinder central axis 4 and is connected with drive motors 8 on being installed in rolling steel cylinder central axis 4 support plates, drive motors 8 drives drive speed reducer 12 runnings by connecting key 9, branch sleeve 10, connecting key 11, drive speed reducer 12 drives rolling steel cylinder axle sleeve 14 by connecting key 13 and rotates in solid housing 16 by rolling bearing 15, and rolling steel cylinder axle sleeve 14 fixedlys connected with rolling steel cylinder 7 to be integral forces rolling steel cylinder 7 to rotate; Rolling steel cylinder central axis 4 by hold-down screw 3 with fixed bearing block 2 be connected bolt and bear driving torque with the vibratory roller frame that fixed bearing block 2 is fixed together.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
