Abstract
The utility model relates to a belt pulley speed changing transmission device. The utility model is composed of a shifting fork, a rotating axle, a small belt pulley, a big belt pulley, a motor belt pulley, a motor and a speed changing rod which are mutually connected, therein, wheel grooves are respectively arranged on the big and small belt pulleys, axle groove are opened on the rotating axle, the speed changing rod is embedded at the center of the rotating axle, one end is connected with the transmission pin, the other end is connected with the spring, and connected with the shifting fork. The utility model adopts belt pulley to change speed, all the other parts except the shifting fork are installed in the belt pulleys coaxially, and the internal space of the belt pulleys is fully utilized. The structural design of the utility model is reasonable and simple, the noise is small, the production cost is low, and non-stopping speed changing can be realized.
Description
(1) technical field
The utility model relates to the mechanical transmission technical field, specifically is meant a kind of belt pulley variable speed drive.
(2) background technique
At present, utilizing shifting slide gear or clutch gear speed change is a kind of common speed change kind of drive, as the oodle maker in the food processing machinery, dough mixing machine, stirrer etc.Traditional shifting slide gear or clutch gear speed change gear structure more complicated, and easily produce noise, variable speed drive takes up room bigger, and in the equipment of some claimed structure compactness, application just is restricted.
(3) summary of the invention
The purpose of this utility model is exactly the defective that exists in the above-mentioned prior art in order to solve, provide a kind of simple in structure, volume is little, noise is little, the belt pulley variable speed drive that can use in the equipment of compact structure.
A kind of belt pulley variable speed drive described in the utility model, by shift fork, rotating shaft, small belt pulley, big belt pulley, motor pulley, motor and speed change lever are interconnected to constitute, wherein, motor pulley is connected with motor, and be in transmission connection with big belt pulley and small belt pulley respectively by belt, big belt pulley and small belt pulley are contained in the rotating shaft by bearing housing respectively, one end of rotating shaft is connected with gear, it is characterized in that, on big belt pulley and small belt pulley, have race, in rotating shaft, have and the vertical corresponding axial trough of race, center in rotating shaft is embedded with speed change lever, one end of speed change lever is connected with the driving pin that level embeds axial trough, and the other end is connected with spring, and is connected with shift fork by the bearing that is inlaid in the spring.
Working principle of the present utility model is: speed change lever is accepted the external speed action by shift fork when speed change, and by bearing and spring generation axial displacement, drive the race that driving pin entered or broke away from big belt pulley or small belt pulley, make rotatablely moving of big belt pulley or small belt pulley pass to driving pin by race, the rotation of drive speed change lever, drive the rotating shaft rotation by axial trough simultaneously, and will rotatablely move by gear and pass; The effect of spring is when the upper and lower motion of shift fork, when if the driving pin of speed change lever does not also align the race of big belt pulley or small belt pulley, convert the displacement movement of speed change lever to spring to the axial pressure on the speed change lever, behind machine startup, when the race of big belt pulley or small belt pulley aligns driving pin, axial pressure promotes speed change lever, driving pin is embedded the race of big belt pulley or small belt pulley, thereby finish the process of the speed change transmission of not stopping.
The utlity model has following advantage and beneficial effect:
1. the utility model only needs to increase a pair of belt pulley and just can realize the speed change transmission process owing to adopted the belt pulley speed change in transmission system, has simplified mechanical structure.
2. the utility model is except that shift fork, and remaining parts all axially is installed in the belt pulley, has made full use of the inner space of belt pulley; And belt pulley has enough inner spaces, can satisfy the design size requirement of variable speed drive part, improves the Element Design rigidity, guarantees to have big as far as possible driving torque.
3. the utility model reasonable in design, simple, noise is little, low cost of manufacture, and can realize not shutting down speed change, very practical.
(4) description of drawings
Fig. 1 is a kind of structural representation of belt pulley variable speed drive.
Fig. 2 and Fig. 3 are a kind of fundamental diagrams of belt pulley variable speed drive.
(5) embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, motor pulley 8 is connected with motor 9, and be connected with small belt pulley 5 with big belt pulley 7 respectively by belt 6, big belt pulley 7 and small belt pulley 5 are sleeved in the rotating shaft 4 by bearing 3 respectively, have race 11 on big belt pulley 7 and the small belt pulley 5, have axial trough 13 in the rotating shaft 4, one end connection gear 10 of rotating shaft 4, speed change lever 14 embeds rotating shaft 4, and the one end is connected with driving pin 12, the other end is connected with spring 2, and is connected with shift fork 1 by bearing 3.
Fig. 1, Fig. 2 and Fig. 3 are respectively the fundamental diagrams that the utility model is in neutral, top gear and bottom gear.As mentioned above, can realize the utility model preferably.
