Abstract
The utility model relates to an automatic mechanism stepless gearbox. A centrifuger, a first gear, a sliding sleeve, a first bevel gear, and a second gear are arranged on a transmission shaft in sequence. A speed governor disk is arranged under the transmission shaft, a shaft line of the speed governor disk and the shaft line of the transmission shaft forms an angle of 90DEG, a sliding shoe is arranged between the first bevel gear and the second gear, and a spring is arranged on the gear II. When the automatic mechanism stepless gearbox runs, the automatic stepless speed regulation is realized because the pusher dog of the centrifugeror drives the first gear and the second gear to slide along the radial direction of the speed governor disk. The automatic mechanism stepless gearbox can adapt the variation of the loading of the automatic mechanism stepless gearbox; the utility model can carry out the stepless speed regulation and commutation by hand. The utility model has the advantages of simple structure, reliable transmission, large transmission ratio, and convenient operation. The utility model is suitable for various motor vehicles and speed changing bicycles, and is widely used for the mechanical transmission systems in various industries.
Description
The utility model relates to a kind of automatic mechanical type stepless speed-regulating device, is used for the automatic stepless speed-regulating of various mechanical transmission.
At present, automatic speed regulation control system majority is to adopt circuit kit to go to control an actuator to carry out automatic speed regulation, because the complex structure of this system, general factory is difficult to manufacturing, and operator also are difficult for checking and discharging for the fault of this system.Though and the fairly simple and reliable transmission of structure of known mechanical stepless arrangements for speed regulation, this device does not have automatic speed regulation because load usually changes, operator are difficult to the accurately coupling of grasp power and load.
The purpose of this utility model is that a kind of automatic mechanical type stepless speed-regulating device will be provided, and it can carry out automatic speed regulation and commutation effectively.
The purpose of this utility model is achieved in that order is loaded onto centrifuge, gear I, sliding sleeve, umbrella tooth I and gear II on transmission shaft, speed disk is arranged on the below of transmission shaft, its axis becomes 90 degree with drive shaft axis, make motion gear piece and the engagement of gear I gear II in the speed disk.Centrifuge and transmission shaft are fixed, and a sliding shoes is set between umbrella tooth I and gear II, and a spring is housed on the gear II.When centrifuge rotated with transmission shaft, the pusher dog of centrifuge overcame spring force by sliding sleeve promotion gear I gear II and slides on transmission shaft, changes the engagement radius of gear I gear II and speed disk, reaches the purpose of automatic stepless speed-regulating.When pushing sliding shoes and handsetting gear II and umbrella tooth I aside with operating handle when chimeric, the gear II is done oppositely output, reaches the purpose of commutation.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an embodiment's of the utility model a tectonic maps.
Fig. 2 is umbrella gear I and the chimeric schematic representation of gear II.
Fig. 3 is that operating handle is pushed the sliding shoes schematic representation aside.
Among Fig. 1, centrifuge (2), gear I (3), sliding sleeve (4), umbrella tooth I (6), gear II (11) order are contained on the transmission shaft (1), and centrifuge (2) is fixing with transmission shaft (1).Symmetry has two elongated slots on the dish of centrifuge (2), respectively adorn a pusher dog in the groove, can in groove, swing an end in contact of the eave tile of pusher dog and gear I (3) after connecting with pin, in the axis hole of gear I (3), have logical keyway, cooperate with retainingf key on the transmission shaft (1).Sliding shoes (12) is arranged between umbrella tooth I (6) and the gear II (11), and the tip engages that has an elongated slot and operating handle (8) on it is contained on the slide bar (13), and slide bar (13) is fixed in housing (14).Spring (10) is housed on gear II (11), and an end withstands on the gear II (11), and an end withstands housing (14).Speed disk (5) is arranged on the below of transmission shaft (1), and its axis becomes 90 degree with transmission shaft (1) axis, and the motion gear piece in the speed disk (5) meshes with gear I (3) gear II (11) respectively.Umbrella tooth II (7) is fixed on the speed disk (5), and umbrella tooth I (6) is enclosed within last and umbrella tooth II (7) engagement of sliding sleeve (4).
During work, transmission shaft (1) drives centrifuge (2) and gear I (3) is rotated, several motion gear piece engagements in the tooth of gear I (3) and the speed disk (5) drive speed disk (5) and rotate, and several other motion gear pieces rotate with gear II (11) engagement driven gear II (11) again in the speed disk (5) simultaneously.The pusher dog of the centrifuge (2) that rotates with transmission shaft (1) is opened by centrifugal action, the power that overcomes spring (10) by sliding sleeve (4) sliding shoes (12) promotion gear I (3) and gear II (11) moves radially along speed disk (5), the rotating speed of gear II (11) is changed continuously, realize stepless speed regulation.Transmission shaft (1) rotating speed is high more, and the pusher dog Zhang Deyue of centrifuge (2) leaves, and gear I (3) is the closer to the center of speed disk (5), and gear II (11) is the closer to the outer rim of speed disk (5), and output speed is also high more.When load increases the reduction of transmission shaft (1) rotating speed, spring (10) overcomes centrifugal force to be promoted gear II (11) and gear I (3) is promoted to speed disk (5) outer rim by sliding sleeve (4) sliding shoes (12) to speed disk (5) center, reduce output speed, output torque is increased, up to reaching transient equiliblium.
During commutation, operating handle (8) is pushed sliding shoes (12) back aside, and axially handsetting gear II (11) is chimeric with the spline of umbrella gear I (6) along transmission shaft (1) by straight pin (9), umbrella gear I (6) driven gear II (11) is rotated do oppositely output, as Fig. 2, shown in Figure 3.
Claims (3)
