Abstract
The utility model relates to a connecting rod small teeth difference speed reducer which belongs to a mechanical transmission device. The device installs three eccentric high-speed shafts on a machine casing to drive two connecting rods with annular gears mutually forming a direction with 180 DEG to make small teeth difference planet engaging transmission with a slow-speed shaft with an external gear. According to different functions, the utility model is provided with one or more than one dynamic force input and output shafts and a vertical and a horizontal type machine models. The device is mainly used as speed reducing transmission and because of the adoption of making the small teeth difference planet engagement of the annular gear of the connecting rod and the external gear of the slow-speed shaft, a single-tooth engaging state in the direct transmission of the gear of an ordinary speed reducer is altered into a multi-tooth engagement, having high overload capability and small possibility of damage.
Description
The utility model belongs to mechanical transmission.
Existing speed reducer adopts the circumferential gear to carry out transmission one to one usually, promptly a pair of direct geared engagement, and if any wherein tooth damage, device then loses normal transmission agency.Other also has a kind of planetary reducer, has been covered with driving gear around central gear, and the gear consumption is big, the output mechanism complexity, and transmission efficiency is low.
The purpose of this utility model is to design a kind ofly with eccentric high speed shaft, and driving has the connecting rod of internal gear to become the fewer differential teeth planetary engagement driving with the lower velocity shaft external gear, and can have a plurality of high speed shafts to be used as power to select to import.
The few tooth difference speed reducer of this linkage type adopt on the eccentric high speed shaft (1) of three bands, be equipped with two internal gears each other two connecting rods (2) of 180 ° of directions make the fewer differential teeth planetary engagement driving with the external gear (3) on the lower velocity shaft (4).
Because high speed shaft (1) the drivening rod internal gear of three band off-centre of employing becomes the fewer differential teeth planetary engagement driving with the external gear (3) on the lower velocity shaft (4), changed the monodentate engagement in the direct transmission of common reducer gear, become multiple tooth engagement, overload capacity is big, and is not fragile.Three high speed shafts (1) all can be used as power input shaft, also can import power simultaneously.
Utilize embodiment shown in the drawings to be described further below.
Fig. 1 is the casing structure figure of the few tooth difference speed reducer of linkage type, and casing shown in Figure 1 illustrated position in Fig. 2 is (5).
Fig. 2 is the inside drive mechanism figure of the few tooth difference speed reducer of linkage type.
In Fig. 2: (1) is depicted as three high speed shafts that band is eccentric; (2) be depicted as two connecting rods of 180 ° of band internal gears each other; (3) be depicted as external gear on the lower velocity shaft; (4) be depicted as low-speed shaft; (5) be depicted as casing.
In the few tooth difference speed reducer of linkage type shown in Figure 2, three eccentric high speed shafts (1) of band are bearing on the casing (5) by six standard piece bearings, on three eccentric high speed shafts (1), installed two each other 180 ° of directions respectively with the connecting rod (2) of an internal gear, constitute two cover quadratic crank mechanisms, the mutual balance of motion centrifugal force of connecting rod, tooth-formation of gear can be involute, also can be cycloid.Because high speed shaft (1) off-centre, the motion of connecting rod (2) composition track shaft, two connecting rods shown in Fig. 2 are 180 ° of dead center positions that residing position is a mechanism kinematic each other.The high speed shaft (1) that three bands that adopt in device are eccentric and the connecting rod (2) of band internal gear constitute four connecting rod band passive constraint mechanisms, have solved the dead point transition of mechanism.In addition lower velocity shaft (4) is shelved on casing (5) by the standard piece bearing, the low speed external gear (3) on the lower velocity shaft (4) with two each other two internal gears of 180 ° connecting rod (2) become fewer differential teeth planetary to mesh.
The above embodiment is a basic model, on the basis of basic model, change with eccentric high speed shaft, the connecting rod of band internal gear, the position and the number of lower velocity shaft, can constitute the few tooth difference speed reducer of derivation type connecting rod of the input of new vertical, horizontal type and multiaxis, output.
Vertical type is that body is upright, claims vertical linkage type few tooth difference speed reducer.Horizontal type is that body is lain on one's side, and the high, low speed axle is vertical with horizontal line, faces upward or downward, and claims the horizontal link lever formula few tooth difference speed reducer.
According to the difference of function, on two connecting rods (2), respectively increase one or more internal gears, and one or more lower velocity shafts of corresponding increase and external gear be meshed, two or two above low speed output shafts can be arranged simultaneously.
Claims (3)
1, the few tooth difference speed reducer of a kind of linkage type, three high speed shafts that band is eccentric have been installed on casing, be equipped with on the axle with two internal gears each other two connecting rods of 180 ° of directions become the fewer differential teeth planetary engagement driving with external gear on the lower velocity shaft, it is characterized in that: three with two on the eccentric high speed shaft each other the connecting rod of 180 ° of directions become the fewer differential teeth planetary engagement with external gear on the lower velocity shaft.
2, the few tooth difference speed reducer of connecting rod according to claim 1 is characterized in that: one or more power input and output axles are arranged.
3, the few tooth difference speed reducer of connecting rod according to claim 1 is characterized in that: vertical and horizontal type is arranged.
