AI Technical Summary
The torque required by large generators during the rotor startup and normal operation stages is different, which makes it difficult for low-torque drives to start the rotor, while high-torque drives consume too much energy during normal operation, resulting in waste of resources.
A relay thrust converting torque output thrust device is designed, and torque output is achieved through the coordination of transmission gear and rack using the alternating action of the spindle and the alternating action of multiple sets of thrust mechanisms.
By utilizing the alternating action of the inertia of the spindle and the thrust mechanism, a thrust power source with a smaller power can be used to improve working efficiency, save energy, and simplify the structure of the drive device.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of power output devices, in particular to a thrust device for relay-type thrust conversion into torque output. Background Art
[0002] The rotor of the generator is driven by an external force (such as a turbine, a steam turbine, a diesel engine, etc.) to rotate in the stator, cutting the magnetic lines of force, thereby generating an induced potential, which is led out through the wiring terminals and connected to the circuit to generate current. For large generators, a large drive device is needed to generate high-torque power to maintain the rotation of the rotor. Due to the effect of inertia, the torque required for the rotor startup phase and the normal operation phase is different. A low-torque drive device is difficult to drive the rotor to start and enter the normal operation phase. When the rotor is operating normally, a high-torque drive device consumes more energy to maintain the operation of the drive device, resulting in a waste of resources. Among them, in order to maintain the speed of the rotor, the power mechanism is currently used to continuously drive the rotor to rotate. Since the rotor has inertia, part of the kinetic energy of the power mechanism is wasted in this process. In addition, the current drive device has a complex structure and a large volume.

[0020] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the following briefly introduces the drawings required for describing the embodiments.
[0021] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] The thrust device for relaying thrust conversion to torque output comprises:
[0024] A main shaft 11, on which a plurality of transmission gears 13 are provided;
[0025] The thrust mechanism 31 includes a thrust power source 32; the thrust power source 32 performs reciprocating motion to intermittently drive the main shaft 11 to rotate;
[0026] A plurality of groups of the thrust mechanisms 31 are arranged in one-to-one correspondence with the transmission gears 13 , and at least two groups of the thrust mechanisms 31 relay to push the main shaft 11 to rotate.
[0027] The utility model provides a thrust device for relaying thrust conversion torque output, which utilizes the inertia of the main shaft and utilizes two thrust mechanisms to act on the main shaft alternately, thereby using a thrust power source with relatively small power, thereby achieving the effect of improving work efficiency and saving energy.
[0028] Further, as a preferred embodiment of the present invention but not limiting, a rack 33 is provided on the output end of the thrust power source 32, and the thrust mechanism 31 includes a transmission assembly 34 provided between the transmission gear 13 and the rack 33. In addition to the use of a rack as the thrust power source, a gear may be used, the transmission assembly may be a belt, or a sprocket may be used, and the transmission assembly may be a chain.
[0029] Further, as a preferred embodiment of the present invention but not a limitation, the transmission assembly 34 includes a first gear 341 meshing with the rack 33, a second gear 342 coaxial with the first gear 341, a third gear 343 meshing with the second gear 342, and a fourth gear 344 coaxial with the third gear 343 and meshing with the transmission gear 13. Since the main shaft has a rotation speed, when the main shaft has inertia, the transmission assembly reduces the torque of the thrust power source and increases the rotation speed, thereby maintaining the current rotation speed of the main shaft. The function of the transmission assembly is similar to that of a reduction box and a pulley mechanism, achieving a labor-saving effect, so that a thrust power source with lower power can be used to achieve an energy-saving effect.
[0030] Further, as a preferred embodiment of the present invention but not limiting, any one of the transmission gear 13, the first gear 341, the second gear 342, the third gear 343 and the fourth gear 344 is a one-way gear. When the rack is reciprocating, the rack extends to drive the main shaft to rotate, and when the rack is retracted, it conflicts with the rotation direction of the main shaft, so a one-way gear is used.
[0031] Further, as a preferred implementation of this solution but not a limitation, the first gear 341 is a one-way gear, and when the rack 33 is extended, the first gear 341 drives the second gear 342 to rotate synchronously, and when the rack 33 is retracted, the first gear 341 rotates relative to the second gear 342. It is a preferred mode of this embodiment that the first gear is a one-way gear.
[0032] Further, as a preferred implementation of the present solution but not a limitation, a gear ratio between the second gear 342 and the third gear 343 is greater than one, and a gear ratio between the fourth gear 344 and the transmission gear 13 is greater than one.
[0033] Further, as a preferred implementation of the present solution but not a limitation, a gear ratio of the second gear 342 to the first gear 341 is greater than one, and a gear ratio of the fourth gear 344 to the third gear 343 is greater than one.
[0034] Further, as a preferred embodiment of the present invention but not limiting, the thrust power source 32 is an electric push cylinder, a hydraulic push cylinder or a pneumatic push cylinder. In addition, the thrust power source can also be in other forms of power.
[0035] Further, as a preferred implementation mode of the present invention but not limiting, the start-up interval time difference between the two thrust mechanisms 31 is less than or equal to the push-out time of the thrust mechanisms 31. Before one thrust mechanism withdraws its force, the other thrust mechanism intervenes, so that the kinetic energy loss is minimized, and the two thrust mechanisms work simultaneously for a short time, thereby avoiding energy waste.
[0036] Further, as a preferred implementation of this solution but not limiting, the push stroke X of the thrust power source 32 is 0-2000 mm, the push speed Y is 0-2500 mm / s, the push time Z=X / Y, and the load is 0-20000 kg.
[0037] Further, as a preferred implementation mode of the present solution but not a limitation, the pushing stroke of the thrust power source 32 is 300 mm, the pushing speed is 500 mm / s, and the pushing time is 0.6 s.
[0038] Further, as a preferred implementation of this solution but not limiting, a support wheel 345 is provided below the rack. The support rack reciprocates in the horizontal direction.
[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
