Description
Technical field
The utility model relates to a kind of variable speed drive that is used for combing machine for fur.
Background technology
The speed change transmission of three transferring rollers of combing machine for fur of the prior art realizes by speed pulley, belt pulley has that match with a belt and inner small and outside big groove usually, and the width of this groove can be regulated, its principle mainly is by regulating the width of pulley groove, thereby the position that makes belt be positioned at groove moves in or out, and reaches the purpose that changes rotating speed then.As a rule, the slewing range of this belt pulley is 80%-120%, and owing to takes place sometimes to slide between belt and the belt pulley to influence the bel-drivenn speed ratio.Because the bel-drivenn speed ratio is inaccurate, and the scope of speed change is wide inadequately, therefore caused the frequent fuds fuddled of transferring roller in the production, cause unstable product quality.
Summary of the invention
The utility model is at deficiency of the prior art, and a kind of simple in structure, slewing range is big, gear ratio is used for combing machine for fur accurately variable speed drive is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of variable speed drive that is used for combing machine for fur, comprise housing, housing is provided with first power transmission shaft that is used for being connected with driving wheel and second power transmission shaft that is used for being connected with follower, all be arranged with on first power transmission shaft and second power transmission shaft by the conical surface taper cone pulley that conical disc and mobile conical disc form that is relatively fixed, be provided with driving belt between two taper cone pulleies, two mobile conical disc are positioned at the same side and can moving axially at first power transmission shaft or second power transmission shaft, the middle of first power transmission shaft and second power transmission shaft is set with the 3rd, go up for the 3rd and be rotatably connected to lever through fulcrum, this lever also is connected on two mobile conical disc simultaneously, and the end of lever is connected with screw rod.The utility model includes two taper cone pulleies that have mobile conical disc, and the fulcrum of lever is positioned at the centre of two conical disc, therefore, when lever rotates around fulcrum, thereby the mobile conical disc of one of them taper cone pulley that will drive an end of lever outwards moves and enlarges the fixedly conical disc of this taper cone pulley and the distance between the mobile conical disc, the position of driving belt in this taper cone pulley moved to the center, and meanwhile, the fixedly conical disc of another taper cone pulley and the distance between the mobile conical disc can be dwindled and the position of driving belt in this taper cone pulley moved to periphery, because having two taper cone pulleies when adjusting, the utility model make the two ends of driving belt change diameter simultaneously, therefore, a slewing range of the present utility model taper cone pulley compared to prior art is big one times.
In order to obtain better technique effect, further technical measures also comprise:
All have the some extended lines groove through conical surfaces summit on the conical surface of said fixing conical disc and mobile conical disc, driving belt is that the contact portion of chain and itself and taper cone pulley is positioned at groove.Because the utility model has adopted the structure of toothed-chain type, the phenomenon of sliding each other can not take place between driving belt and the taper cone pulley again, make gear ratio precision of the present utility model improve greatly.
Preferably, the external part of the external part of above-mentioned first power transmission shaft and second power transmission shaft is positioned at both sides.
Preferably, the external part of the external part of above-mentioned first power transmission shaft and second power transmission shaft is positioned at homonymy.
Two above-mentioned preferred versions should specifically be determined according to equipment and place situation in concrete implementation process, so that it is more suitable for actual conditions.
For convenient when the adjusting screw(rod), for this reason, the end of above-mentioned screw rod is provided with handwheel.
The utility model compared with prior art has following beneficial effect:
1) slewing range is bigger;
2) gear ratio is more accurate.
