Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
Example one
As shown in fig. 1, a plurality of planetary gears g coaxial with each other on a planet carrier H are taken as a group, a transmission mechanism and a plurality of planetary gears g on the same radial plane are taken as a pair, wherein the transmission mechanism is a gear ring b or a sun gear a, and by combining the meshing transmission principle of the planetary gear structure, the number of teeth of the planetary gears of different pairs is different, the number of teeth of the corresponding gear ring and the sun gear is also different, and different pairs correspond to different output speed ratio gears. In view of the above, the present invention provides an automatic speed changing method for a multiple planetary gear transmission, which comprises the following steps:
1. a limiting groove 2 is formed in the inner wall of the shell 1 along the axis direction of the planet wheel, a gear shifting groove 3 is formed in the transmission mechanism of each speed ratio gear along the axis direction of the planet wheel, the notch of the gear shifting groove 3 is opposite to the notch of the limiting groove 2, and the gear shifting grooves 3 on the transmission mechanisms of adjacent speed ratio gears are mutually communicated.
2. A gear shifting mechanism is arranged between the shell 1 and the transmission mechanism, and the side wall of the gear shifting groove 3 pushes the gear shifting mechanism to slide in the limiting groove 2 and the gear shifting groove 3 simultaneously to carry out forward speed regulation.
3. A back-pushing mechanism is arranged between the shell 1 and the transmission mechanism, and the back-pushing mechanism pushes the gear shifting mechanism to slide in the limiting groove 2 and the gear shifting groove 3 simultaneously so as to carry out reverse speed regulation.
Specifically, as shown in fig. 2, 3, and 4, in the multiple planetary gear mechanism, a ring gear is used as a transmission mechanism, and shift grooves 3 are formed in the outer peripheral wall of the ring gear of each gear ratio step. The gear shifting mechanism is a steel ball 5 and a gear shifting return sleeve 6, the gear shifting return sleeve 6 is arranged between the shell 1 and the transmission mechanism, a limiting hole 7 is formed in the gear shifting return sleeve 6, the steel ball 5 is arranged in the limiting hole 7, the return pushing mechanism is a return spring 4, one end of the return spring 4 is fixed to the inner wall of the shell 1, and the other end of the return spring 4 abuts against the gear shifting return sleeve 6. The speed is adjusted in a forward direction by taking the speed ratio from low to high as the forward direction, the groove width of the gear shifting groove 3 is gradually increased along the axis of the planet wheel from a low speed ratio gear to a high speed ratio gear, the output torque is gradually increased during the forward speed adjustment, so under the condition that the input torque is unchanged, when the required output torque is increased, the torque generated by the rotation of the gear ring is increased, the reaction force of the groove wall of the gear shifting groove 3 on the steel ball 5 is also increased, along with the increase of the reaction force and the overcoming of the elastic restoring force of the return spring 4, the side wall of the gear shifting groove 3 pushes the steel ball 5 to simultaneously slide in the limiting groove 2 and the gear shifting groove 3, at the moment, the return spring 4 is gradually compressed, in the process, due to the limiting of the limiting groove 2, when the steel ball 5 is positioned in the gear ring of a certain speed ratio gear, the gear ring of the speed ratio gear ring is stopped to be used as the stopping connection of the multi-connection planet gear mechanism, the multi-connection planetary gear speed change device is combined with a multi-connection planetary gear mechanism, wherein one connection is used as an input connection to input torque, the other connection is used as an output connection to output torque, the multi-connection planetary gear speed change device is used for transmitting and outputting through the speed ratio relation among the stop connection, the input connection and the output connection, the rest connections which do not participate in transmission rotate along with the multi-connection planetary gear speed change device, and therefore speed regulation from a low speed ratio to a high speed ratio can be achieved in the process that the steel ball 5 moves from the gear ring of the low speed ratio gear to the gear ring of the high speed ratio gear.
According to the principle of forward speed regulation, when reverse speed regulation is needed, along with the reduction of required torque, the elastic restoring force of the return spring 4 overcomes the counterforce of the groove wall of the gear shifting groove 3 on the steel ball 5, and then the steel ball 5 is automatically pushed to move from the gear ring of the high-speed gear to the gear ring of the low-speed gear for speed regulation.
When the steel ball 5 is positioned in the gear ring of a certain speed ratio gear, the gear shifting grooves 3 on the two gear rings are communicated at a certain moment along with the rotation of the gear ring which is adjacent to the gear ring of the speed ratio gear and has a higher speed ratio gear than the gear ring of the speed ratio gear, and the steel ball 5 is required to be quickly and stably moved from the gear shifting groove 3 of the low speed ratio gear to the gear shifting groove 3 of the high speed ratio gear during forward speed regulation, so that preferably, as shown in fig. 3, the gear shifting grooves 3 on the gear ring are sequentially divided into an A section, a B section and a C section from small to large according to the groove width, the A section is taken as a binding section, the B section is taken as a working section, the C section is taken as a boosting pushing section, so that the included angle between the side wall surface of the A section and the longitudinal section of the gear shifting groove 3 and the included angle between the side wall surface of the C section and the longitudinal section of the gear shifting groove 3 are both larger than the included angle between the side wall surface of the B section and the longitudinal section of the gear shifting groove 3, thus, after the steel ball 5 slides from the gear shifting groove 3 on the gear ring of the low speed ratio gear ring to the gear ring, the problem that the speed regulation fails due to instantaneous reverse backspacing to the gear shifting groove 3 on the gear ring with the low speed ratio when the steel ball 5 slides in the gear shifting groove 3 on the gear ring with the high speed ratio can be prevented, and meanwhile, the instability of speed regulation caused by the jumping connection of the steel ball 5 during reverse speed regulation can be prevented; the width of the C section is not more than half of the diameter of the steel ball 5, so that the steel ball 5 can be quickly pushed to the shifting groove 3 on the high-speed-ratio gear ring gear by the shifting groove 3 on the low-speed-ratio gear ring gear when the forward speed is regulated.
Example two
In this embodiment, the shift mechanism is replaced by the shift collar 8, and the rest of the structure is the same as that of the first embodiment, as shown in fig. 5, the shift collar 8 includes a sliding ring 81 and a shift cylinder 82, the outer circumference of the sliding ring 81 is a rib sliding in the limiting groove 2, one end of the shift cylinder 82 is connected with the sliding ring 81, the other end of the shift cylinder 82 extends into the shift groove 3 and slides in the shift groove 3, and the return spring 4 is abutted against the sliding ring 81. Accordingly, the speed regulation principle of the present embodiment is the same as that of the first embodiment, and it is sufficient that the width of the C-section is not more than half of the cross-sectional diameter of the shift cylinder 82.
EXAMPLE III
In the present embodiment, the sun gear is used as a transmission mechanism to perform a speed regulation setting, as shown in fig. 6, 7 and 8, one end of the sun gear extends outward to the housing 1 to form a sun gear disk 9, and the shift grooves 3 are formed on the outer peripheral wall of the sun gear disk 9 of each speed ratio shift, and the rest of the structure and the final speed regulation principle are the same as those of the first embodiment.
