Abstract
The invention discloses a small flywheel matched with a polyurethane (PU) wheel. The small flywheel comprises a flywheel shell, a positive and reverse tooth piece, a sleeve, roller needles and a bearing, and is characterized in that: one end of the positive and reverse tooth piece is provided with a tooth shoulder of which the circumference is provided with straight teeth; a bearing is embedded on one side of a middle hole of the tooth shoulder; the sleeve is sleeved on the positive and reverse tooth piece and is tightly pressed against the tooth shoulder; butter is applied and the roller needles are arranged in the recessions of the exposed positive and reverse teeth after the sleeve is sleeved on the positive and reverse tooth piece; the bearing is embedded on one side of an inner hole of the flywheel shell; the flywheel shell which is embedded with the bearing is sleeved at one end where the roller needles are arranged on the positive and reverse tooth piece; therefore, the small flywheel matched with the PU wheel is synthesized.
Description
Technical field:
The present invention relates to a kind of flywheel, particularly a kind of small flywheel that cooperates PU.
Technical background:
Can see in the market, generally be the flywheel that cooperates ordinary bicycle.And, being difficult to seek suitable flywheel for PU wheel, the design people once formerly designed the small flywheel of a PU wheel, and (patent No. is: Z:2009-20073231X), but this design performance and stability are undesirable.
Summary of the invention:
Purpose of the present invention will provide a kind of being more suitable for to cooperate with the PU wheel, and performance is better, the small flywheel of the cooperation PU wheel that stability is stronger.The object of the present invention is achieved like this, the small flywheel that cooperates the PU wheel, comprise the flywheel hub, fall along tooth spare sleeve pipe, needle roller and bearing is characterized in that, fall along tooth spare one, the tooth shoulder that one circumference band straight-tooth is arranged, one side tooth shoulder mesopore also stud with a bearing, also be with a sleeve pipe along on the tooth spare falling, sleeve pipe is close to the tooth shoulder, falling falling along on the tooth of exposing after suitable tooth spare puts sleeve pipe, the place spreads butter with mark of mouth, and puts needle roller, one side of flywheel hub endoporus also studs with a bearing, to stud with the flywheel hub of bearing, be socketed in down along tooth spare and put of needle roller, just synthesized a small flywheel that can cooperate the PU wheel.
The invention has the beneficial effects as follows: tooth shoulder of the present invention is taken turns to cooperate with PU and is easy to, and only need be pressed into the endoporus that the PU wheel is put bearing, and with the tooth shoulder endoporus on one side and the endoporus on flywheel hub one side, each inlays a bearing, and it is more sliding suitable to allow the PU hub get, and small flywheel is more durable.
Description of drawings
Fig. 1 is a structural front view of the present invention
Fig. 2 is a structure side pseudosection of the present invention
Fig. 3 is appearance figure of the present invention
Among the figure: 1-flywheel hub, 2-fall along tooth spare, 3-sleeve pipe, 4-needle roller, 5-bearing, the suitable tooth spare 2 that wherein falls also comprises: 21-fall along tooth 22-tooth shoulder.
Embodiment:
According to Fig. 1, Fig. 1, the small flywheel of described cooperation PU wheel comprises flywheel hub 1, falls along tooth spare 2 sleeve pipe 3, needle roller 4 and bearing 5;
Described flywheel hub 1 is the periphery of sprocket teeth, and the centre is a tubulose, and the end in the [studs with described bearing 5;
Described along tooth spare 2, comprise down along tooth 21 and tooth shoulder 22, described along tooth 21 shapes such as milling cutter, the excircle that described tooth shoulder 22 is circles has tooth, described tooth shoulder 22 connects into described along tooth spare 2 with described suitable tooth 21 one, described is the metallurgical part of powder along tooth spare 2, and the described tooth of described suitable tooth spare 2 is takeed in the 22 circle holes, studs with a described bearing 5.
With described flywheel hub 1, described along tooth spare 2, described sleeve pipe 3, described needle roller 4 and two described bearings 5, composite assembly just can obtain the small flywheel of described cooperation PU wheel.
