Abstract
The utility model relates to a single flywheel speed-transmitter and is characterized in that the speed-transmitter comprises a shaft housing seat and coaxial shoulder holes which are arranged in the center of the shaft housing seat, and the diameters of the coaxial shoulder holes are from small to large, wherein, the shoulder hole with a small diameter is used for the passing through of an axle hole of a transmission shaft, the diameter of the axle hole is slightly bigger than the transmission shaft, the perisporium of the excircle of the axle hole is provided with gears or chain wheels the number of which is between 9-15; the shoulder hole with a big diameter is a bearing switch port which is used for being matched and connected with a fitted bearing of the transmission shaft, a unilateral driver is arranged between the perisporium of the excircle of the bearing switch port and the shaft housing seat. The single flywheel speed-transmitter of the utility model can not only satisfy rich installation space, but also greatly increase speed-transmitting ratio of the flywheel speed-transmitter and accelerate the transmission speed of the flywheel speed-transmitter.
Description
Technical field
The utility model relates to a kind of machinery biography quick-mounting to be put, particularly a kind of single freewheel speed-transmitter, and it mainly is applicable to the biography speed on bicycle freewheel or other the various flywheels.
Background technique
Present existing flywheel speed-transmitter (the particularly flywheel speed-transmitter on the bicycle rear) only is made up of the gear or the sprocket wheel that are in transmission connection with driving wheel basically, and gear or sprocket wheel directly are socketed in the bearing periphery during use, and bearing directly is socketed in the transmission shaft periphery; When requiring unidirectional transmission, also unidirectional driver must be set between gear or sprocket wheel and the bearing.Therefore, when making, must do gear or sprocket wheel bigger, could leave abundant space in gear or sprocket wheel inside and assemble unidirectional driver and bearing, gear or sprocket wheel occupation space volume are big so on the one hand, the wheel footpath is big on the other hand, the number of teeth is many can cause the transmission velocity ratios reduction, transmission speed is slow, and for example the flywheel speed-transmitter minimum on the bicycle rear can only be made the gear or the sprocket wheel of 16 teeth, therefore causes defectives such as riding speed is slow, volume is big.
The model utility content
In order to solve the above-mentioned defective of existing in prior technology, the utility model provides a kind of single freewheel speed-transmitter, and it can improve the transmission velocity ratio of flywheel speed-transmitter greatly when satisfying abundant assembly space, accelerates the transmission speed of flywheel speed-transmitter.
The technical solution of the utility model is to constitute like this, it comprises sleeve block, the middle part of sleeve block is provided with the ascending coaxial shoulder hole of diameter, wherein the hole that diameter is little is the axis hole that is used for placing transmission shaft, the slightly larger in diameter of axis hole is in transmission shaft, and the outer circle wall of axis hole is provided with gear or the sprocket wheel of the number of teeth between the 9-15 tooth; The hole that diameter is big is to be used for the bearing attachment hole that fitted bearing with transmission shaft is connected, and is provided with unidirectional driver between the outer circle wall of described bearing attachment hole and the sleeve block.
During use, the inner ring of fitted bearing is connected with the transmission shaft drive fit, and the outer ring is connected with bearing attachment hole drive fit, and the axis hole sky is enclosed within the transmission shaft periphery.When external drive wheeling driving gear or sprocket wheel forward rotation (as shown in Figure 3), gear or sprocket wheel drive the transmission shaft forward rotation then by unidirectional driver, the fitted bearing of sleeve block drive opposite side; When external drive wheeling driving gear or sprocket wheel backward rotation, because the effect of unidirectional driver, gear or sprocket wheel idle running, and transmission shaft does not rotate.
Than prior art, the utility model is set to the coaxial shoulder hole be made up of axis hole and bearing attachment hole owing to be connected the hole of transmission with transmission shaft, and gear or sprocket wheel be located at axis hole one side, and fitted bearing and unidirectional driver are located at bearing attachment hole one side, therefore both can provide abundant assembly space to be used for assembling unidirectional driver and fitted bearing, can reduce the wheel footpath and the number of teeth of gear or sprocket wheel again, thereby improve the transmission velocity ratio of flywheel speed-transmitter greatly, accelerate the transmission speed of flywheel speed-transmitter.
In the utility model technique scheme, in order to reach best transmission velocity ratio, the number of teeth of described gear or sprocket wheel is preferably 9 teeth.

Embodiment
Below in conjunction with specification drawings and specific embodiments the utility model content is elaborated:
As Fig. 1-Figure 4 shows that a kind of single freewheel speed-transmitter that the utility model provides, it comprises sleeve block 1, the middle part of sleeve block is provided with the ascending coaxial shoulder hole of diameter, wherein the hole that diameter is little is the axis hole 3 that is used for placing transmission shaft 2, the slightly larger in diameter of axis hole is in transmission shaft, and the outer circle wall of axis hole is provided with gear or the sprocket wheel 4 of the number of teeth between the 9-15 tooth; The hole that diameter is big is to be used for the bearing attachment hole 6 that fitted bearing 5 with transmission shaft is connected, and is provided with unidirectional driver 7 between the outer circle wall of described bearing attachment hole and the sleeve block.
Described unidirectional driver can adopt existing on the market various structural types, a kind of unidirectional driver schematic representation that adopts for the utility model as shown in figures 1 and 3 wherein, it comprises outer circle 71, be located at the interior circle 72 in the outer circle and be located at roller 73 between the inside and outside circle, wherein outer circle and sleeve block is set to one or drive fit links together, the inner circumference of interior circle forms bearing attachment hole 6; Be provided with small free gap between the inside and outside circle, the external peripheral surface of interior circle is evenly distributed with oblique groove 74, and roller places in the oblique groove, and the radial depth in the oblique groove is just being transported moving direction by diminishing greatly gradually along interior circle.The utility model is not limited to adopt illustrated this unidirectional driver structure, also can adopt the unidirectional driver of other different structure shape when specifically using, as the ratchet of the transmission that can be connected, pawl device etc.
The best number of teeth of said gear or sprocket wheel 4 is 9 teeth.
