Abstract
The utility model relates to a moving model speed changing transmission device, which is composed of an input shaft, a middle shaft, an output shaft, and a gear set, wherein, the input shaft, the middle shaft, and the output shaft are parallel with each other. The input shaft and the middle shaft are provided with the same number of cone pulleys which are matched with the shafts in a slide way, each cone pulley is composed of a big cylindrical gear and a small cylindrical gear, which have the same module, and the shaft distance of the input shaft and the middle shaft can ensure that the big cylindrical gears and the small cylindrical gears of the cone pulleys of the different shafts can be engaged across. The output shaft is provided with a big cylindrical gear which is matched with the shaft in a slide way and can be fixed on any position of the shaft, and the big cylindrical gear can be engaged with the small cylindrical gear of any cone pulley on the middle shaft. The utility model has the advantages of small size and simple structure; a plurality of speed reducing ratios and big speed reducing ratio can be obtained.
Description
The utility model belongs to variable speed drive, relates to a kind of movable model speed change driver.
Gear change-speed gearing is extensive use.When needs obtained than transmission ratio, the method for taking generally was the quantity that increases gear pair.But the increase of gear pair quantity often causes the increase of jack shaft, correspondingly will solve a series of problems such as supporting of axle, has increased volume on the one hand, also makes structure become very complicated simultaneously.Different velocity ratios is provided if desired, also needs to increase devices such as clutch.These shortcomings are given to use on movable model and are caused many obstacles.
It is a kind of simple in structure that the purpose of this utility model is to provide, and the variable speed drive that volume is little can obtain high reduction speed ratio, and different reduction speed ratio, do not need clutch, is particularly suitable for using on small-sized movable model.
The utility model is achieved through the following technical solutions: a kind of movable model three class gear shift driver, to form by tank tower, first jack shaft, second jack shaft, torque output shaft, 6 bidentate wheels and a moment of torsion output gear etc., and the tank tower section is
Shape is equipped with first jack shaft, second jack shaft and the torque output shaft that are parallel to each other on tank tower; Described bidentate wheel is by a cylindrical gears and mutual fastening being combined into one of disk gear that diameter is bigger that diameter is less, the through hole that is a bit larger tham the jack shaft diameter is arranged on its common center line, and 6 bidentate wheel spaces are set on two jack shafts; Described moment of torsion output gear is sleeved on the torque output shaft, can slippage and be fixed on a certain gear in three gears with screw.The modulus of all gears is all identical, and the number of teeth of 6 cylindrical gearss is identical, and the tooth module of 6 disk gears is also identical.First jack shaft is identical with the second jack shaft diameter, all be fixedly mounted on the tank tower, and torque output shaft can rotate in bearing hole by the tank tower bearing hole; Distance between first jack shaft and second jack shaft just in time is cylindrical gears and disk gear meshing distance, and the distance of second jack shaft and torque output shaft just in time is the engagement distance of moment of torsion output gear and cylindrical gears.First disk gear on first jack shaft is meshed with the cylindrical gears on the motor, and this disk gear also can be the circle bevel gear.
Description of drawings is as follows:
Fig. 1 is the utility model structural drawing;
Fig. 2 is the utility model embodiment two structural drawing;
Fig. 3-5 is 3 kinds of different reduction speed ratio key plan.
Be described further below in conjunction with drawings and Examples:
Fig. 1 has showed an embodiment of the present utility model, the 1st jack shaft (7), the 2nd jack shaft (8), parallel being contained in of torque output shaft (9)
On the shape opening tank tower (14), bidentate wheel (1), (3), (5) be loaded in the same way on the 1st jack shaft (7), bidentate wheel (2), (4), (6) be loaded on the jack shaft (8), direction and bidentate wheel (1), (3), (5) identical, bidentate wheel (2), (4), (6) the disk gear on is taken turns (1) with bidentate respectively, (3), (5) the cylindrical gears engagement on, bidentate wheel (2), (4) cylindrical gears on is taken turns (3) with bidentate respectively, (5) the disk gear engagement on, the gearwheel of bidentate wheel (1) can also can be circle bevel gear (see figure 2) for the disk gear, and with motor (12) on cylindrical gears (13) engagement, moment of torsion output gear (10) is fixed on the output shaft (9) by positioning screwn (11).Fig. 3--5 have represented the position of three kinds of different speed ratios, cylindrical gears on moment of torsion output gear (10) and the bidentate wheel (2) is a retaining speed change when meshing, during with cylindrical gears engagement on the bidentate wheel (4) is two retaining speed changes, during cylinder engagement on moment of torsion output gear (10) and the bidentate wheel (6) is three to keep off speed changes.
On the axle of motor (12) cylindrical gears (13) is housed, can drive bidentate wheel (1) → bidentate wheel (2) → moment of torsion output gear (10) → torque output shaft (9) by cylindrical gears (1) and constitute a retaining speed change of three grades of reduction speed ratio, also can drive bidentate wheel (1) → bidentate wheel (2) → bidentate wheel (3) → bidentate wheel (4) → moment of torsion output gear (10) → torque output shaft (9) and constitute the two retaining speed changes that Pyatyi is slowed down by cylindrical gears (13), also can drive bidentate wheel (1) → bidentate wheel (2) → bidentate wheel (3) → bidentate wheel (4) → bidentate wheel (5) → bidentate wheel (6) → bidentate wheel (7) → moment of torsion output gear (10) → torque output shaft (9) and constitute three retaining speed changes of seven grades of decelerations by cylindrical gears (13), all modules are identical, and reduction speed ratio can be by 200--20000:1.
The utility model comprises that output shaft only has 3 axles, and all gears all are slidingly matched and are contained on the axle, and are easy to assembly, reduced volume, saved many axles and bearing device, simple in structure.Different on the output shaft on big column gear and the jack shaft are taken turns engagement and can be obtained different reduction speed ratio, because volume is little, simple in structure, cost reduces, and can obtain several a thousandths of hundreds of so that bigger reduction speed ratio.
