Abstract
The utility model discloses an oblique cycloid gear. The oblique cycloid gear comprises a cycloid gear meshed with a group of annularly arrayed needle teeth on a pin gear; the needle teeth form an oblique cylinder; the outer peripheral tooth surface of cycloid wheel and the side surfaces of the needle teeth are matched to fit with the transmission direction to form a slope. The contact area between the cycloid gear and the needle teeth is large, the stressing is uniform, and the cycloid gear is high in transmission efficiency and long in service life.
Description
Technical field
The utility model relates to retarder technology, relates in particular a kind of tiltedly cycloidal gear.
Background technique
The Gear Planet Transmission mode of engagement in driving mechanism in existing balancing point pinwheel reducer adopts conventionally, referring to Fig. 1, driving mechanism comprises: input shaft 11, eccentric bushing 12, gear pin 13, pin gear sleeve 14, cycloid wheel 15, output shaft 16, pin 17, column sleeve 18.Z
hindividual gear pin 13 is socketed respectively a pin gear sleeve 14, and according to default pinwheel reference radius equal angles circle distribution fixing, like this, Z
hindividual pin gear sleeve 14 has just formed the pinwheel as the central gear of Gear Planet Transmission, and the axial alignment of the center of this pinwheel and input shaft 11 and output shaft 16.Cycloid wheel 15 is as the planet wheel of Gear Planet Transmission, and have for the multiple tooth Z engaging of pin gear sleeve 14
cindividual tooth.The central position of cycloid wheel 15 has the first circular hole, the one end that is used as the eccentric bushing 12 of planet carrier is inserted in the first circular hole by a bearing (not shown), and the other end of eccentric bushing 12 is socketed on input shaft 11, be connected with the bias of output shaft 16 thereby realize cycloid wheel 15.
Like this, when input shaft 11 with angular velocity n in the time that its axis is rotated in the forward, cycloid wheel 15 or under the drive of eccentric bushing 12 around the axis of input shaft 11 circle, and by the rotation with multiple tooth engagement of pin gear sleeve 14 of its cycloid tooth, thereby by column sleeve 18 and pin 17 on output shaft 16 lands 19, drive output shaft 16 with angular velocity n/Z
ccounterrotating.
Above-mentioned existing planet-cycloid reducer, cycloid wheel is meshed with the pin tooth (gear pin) of one group of annular array on pin gear, to form the poor interior engaging speed reducer structure as a tooth of tooth (in order to reduce friction, in the little speed reducer of speed ratio, on pin tooth with pin gear sleeve), realize and slowing down by its driving mechanism.For in traditional cycloidal gear rotating mechanism, the flank profil of pinwheel is cylndrical surface, as shown in Figure 2, the pin gear sleeve 14 of gear pin 13 and socket is cylindrical, in cycloid wheel 15, form the gear that coordinates cylindrical pinwheel transmission, form corrugated arc shaped surface, thus the gear teeth in cycloid wheel respectively and with columniform pin tooth engagement driving.For columniform pin toothing, cycloidal gear and pin tooth contact area are little, and cycloidal gear transmission efficiency is general, and working life is short.In the structural design of the design people for above-mentioned pinwheel, do not attain perfect caused disappearance, and deeply design, and active research improvement has a fling at and development and Design goes out this creation.
Model utility content
The purpose of this utility model is to provide a kind of tiltedly cycloidal gear, and this cycloidal gear and pin tooth contact area are large, stressed even, and cycloidal gear transmission efficiency is high, long service life.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of oblique cycloidal gear, comprises that cycloid wheel is meshed with the pin tooth of one group of annular array on pinwheel, and pin tooth forms oblique circular cylinder body, and the flank of tooth of cycloid wheel periphery coordinates the direction of pin flank laminating transmission to form plane of inclination.
Adopt after said structure, the pin tooth of cycloid wheel is formed oblique circular cylinder body by the utility model, it is large that the area of contact of the contact area rate common cycloid gear between cycloidal gear and pin tooth is wanted, therefore contact ratio is large, stressed even, engagement property is good, stable drive, noise are little, has reduced the load of every pair of gear, has improved the bearing capacity of gear.

Embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Main improvements of the present utility model are coordinating of cycloid wheel and pin tooth in cycloidal gear structure, and in conjunction with shown in Fig. 3 to Fig. 5, in the utility model, cycloid wheel 2 is meshed with the pin tooth 3 of one group of annular array on pin gear.Main improvements of the present utility model are the structure of pin tooth, thereby increase the area of contact between cycloidal gear and pin tooth 3, as shown in the figure, pin tooth 3 in the utility model forms oblique circular cylinder body, corresponding, the flank of tooth of cycloid wheel 2 peripheries coordinates the direction of oblique circular cylinder type pin tooth 3 side laminating transmissions to form plane of inclination, and the gear teeth 21 are parallel with pin tooth 3, and the oblique circular cylinder body side surface of pin tooth 3 carries out transmission on the cycloid wheel periphery flank of tooth.
The pin tooth 3 of cycloid wheel is formed oblique circular cylinder body by the utility model, the oblique structure of cycloidal gear and pinwheel, different from the flank profil of the pinwheel of the cylndrical surface in traditional cycloidal gear rotating mechanism, adopt such cooperating structure, the in the situation that of same thickness, it is large that the area of contact of the contact area rate common cycloid gear between cycloidal gear and pin tooth 3 is wanted, therefore contact ratio is large, stressed even, engagement property is good, stable drive, noise are little, reduce the load of every pair of gear, improved the bearing capacity of gear.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
