Abstract
The utility model relates to a drive change device for a straight-tooth bevel gear wheel, which is most different from the previous variable speed gear in that the former adopts straight-tooth bevel gear drive, and utilizes the characteristic that straight-tooth bevel gear wheels with different semidiameters on the same disk have the same gear size but different numbers of teeth. Another slide gear is utilized to contact the straight-tooth bevel gear wheels with different semidiameters. The rotation speeds in unit time of the driving shaft driven by the slide gear are different, so that the purpose of changing speed is achieved. The device can also adopt simultaneously multidirectional output manner, each output terminal with a different rotation speed, applicable for speed changing of automobiles and bicycles.
Description
The utility model relates to a kind of by spur bevel gear transmission and the device that carries out speed governing.
People are carrying out mechanically operated the time, always different machines are required different rotating speeds, and this just need adjust with speed changer.And traditional speed changer exists the complicated and inefficient shortcoming of transmission, and this is with regard to the simple and efficiently speed change gear of a kind of transmission of needs.
It is a kind of simple in structure, easy to operate that the purpose of this utility model will provide exactly, the novel speed change gear that transmission efficiency is high.
Based on above-mentioned purpose, the novel speed change gear that the utility model proposes the transmission of this employing spur bevel gear and carry out speed governing.Its same difference of speed changer in the past is there is not too much driving gear, during each the use sliding gear is contacted with required spur bevel gear, because adopt the spur bevel gear transmission, transmission direction is changed on the basis of former direction simultaneously.And multidirectional output simultaneously, each output terminal can have different rotating speeds, and little, the required part of whole device volume is few, and transmission efficiency is improved.
Below in conjunction with accompanying drawing the utility model is described further, as shown in Figure 1 and Figure 2.Fig. 1 is the side view of the spur bevel gear drive transmission device that the utility model proposes, and Fig. 2 is a plan view.This device comprises: transmission shaft 1 and transmission shaft 5, and the wheel disc 2 on the transmission shaft 1, the spur bevel gear 3 on the wheel disc, and be enclosed within sliding gear 4 on the transmission shaft 5.The spur bevel gear of different radii has the big or small identical of tooth and characteristics that the number of teeth is different on the wheel disc, and when machine drove transmission shaft 1 and rotates, wheel disc 2 and then rotated.Contact the number of teeth difference that turns over because the angle that the spur bevel gear of different radii turns over is identical if be enclosed within the spur bevel gear of different radii on sliding gear on the transmission shaft 5 and the wheel disc in good time in the unit time.So when it drives sliding gear.The rotating speed of sliding gear in the unit time is inevitable different.Thereby reach the purpose of speed change.When transmission shaft 1 as driving shaft, transmission shaft 5 can be loaded onto the device of several similar transmission shafts 5 during as driven shaft simultaneously on wheel disc.So just can reach the purpose of multidirectional output simultaneously and on each driven shaft, can obtain different rotating speeds.
The utility model is suitable for the frequent occasion of those speed governing most.As the gearbox of automobile and the speed changer of bicycle etc.
Claims (3)
1, a kind of novel spur bevel gear drive transmission device comprises:
Transmission shaft, wheel disc, spur bevel gear, it is characterized in that: wheel disc 2 is fixed on the transmission shaft 1, the different spur bevel gear of radius 3 is arranged on wheel disc 2, sliding gear 4 relies on key and transmission shaft 5 to connect, and the corresponding sliding gear on the spur bevel gear of the different radii on the wheel disc 2 and the transmission shaft 5 is meshed.
2, speed change gear according to claim 1 is characterized in that the modulus of the spur bevel gear that radius is different is identical.
3, according to claim 1,2 described speed change gears, it is characterized in that: when transmission shaft 1 as driving shaft, transmission shaft 5 during as driven shaft, when using at every turn, a sliding gear and corresponding spur bevel gear engagement on each driven shaft.
