Abstract
The invention relates to a constant ratio transmission device of a roller wheel. The constant ratio transmission device of the roller wheel comprises a horizontal driving shaft (1), a chain wheel (3) sleeving the driving shaft (1), a driven shaft (6) perpendicular to the driving shaft (1) and a roller wheel body (7) in key joint with the driven shaft (6). A slotted taper sleeve (4) is arranged between the chain wheel (3) and the driving shaft (1) in a matching mode and is fixedly connected with the chain wheel (3) through a first screw (5); small bearings (9) are evenly distributed on and connected with the periphery of the roller wheel body (7) through second screws (10). After adopting the technical scheme, the constant ratio transmission device of the roller wheel has the technical effects of being free of maintenance and capable of achieving vertical transmission at a big constant ratio.
Description
Technical field
The present invention relates to a kind of transmission device, particularly relate to a kind of roller wheel Fixed ratio transmissions.
Background technique
In the stable drive ratio mechanism of some vertical transmission campaigns, have the type of belt drive such as gear transmission, worm and worm gear, but these transmission costs are all comparatively large, the process-cycle is also long, especially for use in the occasion of some big speed ratios, these structural requirements have good lubricating condition simultaneously.For overcoming above shortcoming, a kind of easy vertical transmission movement means need be designed, by the combination of mechanical parts, realizing the transmission of motion and non-maintaining.
Summary of the invention
The object of this invention is to provide a kind of non-maintaining large stable drive ratio device that can realize vertical transmission campaign.
The technological scheme realizing above-mentioned purpose is: a kind of roller wheel Fixed ratio transmissions, comprise the driving shaft of horizontal arrangement, the sprocket wheel be sleeved on driving shaft, take turns body with the vertically arranged driven shaft of driving shaft and the roller that connects with driven shaft key, be combined with the tapered sleeve that cracks between sprocket wheel and driving shaft, the tapered sleeve that cracks is fixedly connected by the first screw and sprocket wheel; Roller wheel body circumferentially connected little bearing by the second screw is uniform.
Further, the left side of described sprocket wheel 3 is provided with adjustment axle sleeve, and is close to the end face at adjustment axle sleeve.
Further, little bearing and roller are taken turns between body and are provided with bearing spacer, by described bearing spacer and by the second screw be fixed to roller take turns body circumferentially.
Further, sprocket wheel 3 pitch and roller take turns the pitch of little bearing on body is identical.
After adopting technique scheme, there is following beneficial effect:
(1) effectively can simplify drive mechanism, cut down finished cost;
(2) transmission accuracy of driving mechanism is improved;
(3) the non-maintaining of driving mechanism can be realized, increase work efficiency.

In figure: 1. driving shaft; 2. adjust spacer; 3. sprocket wheel; 4. crack tapered sleeve; 5. the first screw; 6. driven shaft; 7. roller wheel body; 8. bearing spacer; 9. little bearing; 10. the second screw.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
As shown in Fig. 1 ~ 2: a kind of roller wheel Fixed ratio transmissions, comprise the driving shaft 1 of horizontal arrangement, the sprocket wheel 3 be sleeved on driving shaft 1, with the vertically arranged driven shaft 6 of driving shaft 1 and take turns body 7 with the roller of driven shaft 6 key connecting, be combined with the tapered sleeve 4 that cracks between sprocket wheel 3 and driving shaft 1, the tapered sleeve 4 that cracks is fixedly connected with sprocket wheel 3 by the first screw 5; Roller wheel body 7 circumferentially connected little bearing 9 by the second screw 10 is uniform.
Further, for improving the precision of transmission of the present invention, expand using scope of the present invention, the left side of described sprocket wheel 3 is provided with adjustment axle sleeve 2, and is close to the end face at adjustment axle sleeve 2.
Further, in order to reduce maintenance workload of the present invention, improve working life of the present invention, little bearing 9 and roller are taken turns between body 7 and are provided with bearing spacer 8, by described bearing spacer 8 and by the second screw 10 be fixed to roller take turns body 7 circumferentially.
Further, for ensureing the stationarity of transmission, improve the precision of transmission of the present invention, the pitch that sprocket wheel 3 pitch and roller take turns little bearing 9 on body is identical.
Working principle of the present invention is as follows: sprocket wheel 3 endoporus and the tapered sleeve 4 that cracks of transferring power coordinate, and being screwed into by the first screw 5, hold tightly on driving shaft 1; Roller wheel body 7 has been installed on the driven shaft 6, and by key transferring power.Little bearing 9 has been connected roller wheel the circumferentially uniform of body 7.Little bearing 9 embeds the end face notch of sprocket wheel 3, combine according to sprocket wheel and chain the principle transmitting motion, little bearing 9 is equivalent to the roller in chain, utilizes sprocket wheel 3 in revolution, promote each little bearing 9, drive roller wheel body 7, driven shaft 6 turn round thus, complete the vertical transmission of motion at this point.
