Abstract
Provided is a power booster for a bicycle. The power booster for the bicycle comprises an input shaft, a chain wheel and a box body. An arc-shaped bearing support is fixedly connected with an outer side of one side of the box body through screws. The box body and the arc-shaped bearing support are provided with the input shaft through a bearing. The input shaft is provided with a conical gear A, a surface bearing, and a needle bearing inner sleeve from left to right. The needle bearing inner sleeve is provided with a cylindrical gear A, a needle bearing and the chain wheel from left to right. A key joint is arranged among the chain wheel, the cylindrical gear A and the needle bearing inner sleeve. A worm-wheel shaft which is parallel to the input shaft is provided with a cylindrical gear B and a worm wheel. The cylindrical gear B and the cylindrical gear A are mutually meshed. Worm shafts which are mutually vertical and interlaced are arranged above the worm-wheel shaft. The worm shafts are arranged on a worm shaft hanging foot through a bearing. The worm shaft hanging foot is fixedly connected inside a box cover. A conical gear B which is arranged on the worm shafts and the conical gear A are mutually meshed. The power booster for the bicycle has the advantages of being simple and reasonable in structure. The power booster for the bicycle is easy to ride and the power booster for the bicycle saves time and labor.

The purpose of this utility model provides a kind of simple and reasonable, light, time saving and energy saving foot-operated strengthener vehicle of riding.
The utility model is to realize like this, a kind of foot-operated strengthener vehicle, comprise input shaft, sprocket wheel, casing, it is characterized in that: described casing is fixedly connected with the bow profile shaft by screw on one side and holds support, casing and bow profile shaft hold support and are provided with input shaft by bearing, are provided with from left to right conical gear A, surface bearing, needle bearing inner sleeve on the input shaft; Put in the needle bearing and be provided with from left to right cylindrical wheel A, needle bearing, sprocket wheel, be provided with key between described sprocket wheel and cylindrical wheel A and the needle bearing inner sleeve and be connected; Be provided with cylindrical wheel B and worm gear on the worm-wheel shaft that be arranged in parallel with input shaft, described cylindrical wheel B is meshed with cylindrical wheel A; Be provided with orthogonal staggered worm shaft above the worm-wheel shaft, worm shaft is arranged on the worm shaft hanging feet by bearing, and the worm shaft hanging feet is fixedly connected on the case lid inboard by screw, and the conical gear B that arranges on the worm shaft is meshed with conical gear A.
Worm shaft described in the utility model is provided with multi-start worm screw.
Needle bearing inner sleeve described in the utility model and input shaft are set to free-running fit.
The utility model is simple and reasonable, it is light, time saving and energy saving to ride.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure 1, input shaft, 2, surface bearing, 3, needle bearing inner sleeve, 4, needle bearing, 5, sprocket wheel, 6, cylindrical wheel A, 7, conical gear A, 8, cylindrical wheel B, 9, conical gear B, 10, worm shaft hanging feet, 11, worm shaft, 12, worm-wheel shaft, 13, bow profile shaft hold support, 14, worm gear, 15, case lid, 16, casing.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, a kind of foot-operated strengthener vehicle, comprise input shaft 1, sprocket wheel 5, casing 16, it is characterized in that: described casing 16 is fixedly connected with the bow profile shaft by screw on one side and holds support 13, casing 16 and bow profile shaft hold support 13 and are provided with input shaft 1 by bearing, are provided with from left to right conical gear A7, surface bearing 2, needle bearing inner sleeve 3 on the input shaft 1; Be provided with from left to right cylindrical wheel A6, needle bearing 4, sprocket wheel 5 on the needle bearing inner sleeve 3, be provided with key between described sprocket wheel 5 and cylindrical wheel A6 and the needle bearing inner sleeve 3 and be connected; Be provided with cylindrical wheel B8 and worm gear 14 on the worm-wheel shaft 12 that be arranged in parallel with input shaft 1, described cylindrical wheel B8 is meshed with cylindrical wheel A6; Be provided with orthogonal staggered worm shaft 11 above the worm-wheel shaft 12, worm shaft 11 is arranged on the worm shaft hanging feet 10 by bearing, worm shaft hanging feet 10 is fixedly connected on case lid 15 inboards by screw, and the conical gear B9 that arranges on the worm shaft 11 is meshed with conical gear A7.Described worm shaft 11 is provided with multi-start worm screw.Described needle bearing inner sleeve 3 is set to free-running fit with input shaft 1.During implementation, casing input shaft in the utility model all can be placed in the vehicle frame axis position of existing human powered vehicle, and two ends installation dimension and existing human powered vehicle pedal are supporting on the input shaft, and sprocket wheel is connected by chain with sprocket wheel on the human powered vehicle.Under input shaft conical gear A drove, multi-start worm screw drove the purpose that worm gear is pass on reinforcement.Worm shaft is installed in the case lid inboard so that Assembly And Maintenance by two ends hanging feet axle; The cylindrical wheel A that is meshed with cylindrical wheel B on the worm-wheel shaft and the sprocket wheel that relies on the transmission of needle bearing inner sleeve are equipped with respectively in needle bearing inner sleeve two ends, putting assembly set in the needle bearing is supported by single needle bearing, the inner sleeve left surface is equipped with surface bearing, and needle bearing inner sleeve and input shaft produce relative motion during running; Input shaft up-bow type support head bearing, casing head bearing and needle bearing inner sleeve are wanted on the same axial line.Conical gear A on the input shaft drives conical gear B rotation on the worm shaft, worm screw drives worm-wheel shaft and rotates, cylindrical wheel B drives cylindrical wheel A rotation on the worm-wheel shaft, cylindrical wheel A drives the needle bearing inner sleeve and rotates, drive sprocket rotation by flat key on the needle bearing inner sleeve outer ring, this moment the needle bearing inner sleeve with input shaft generation relative motion, Input Forces is passed to driving chain sprocket after by the mechanical drive reinforcement, under the traction of chain, vehicle is moved ahead.
