Abstract
The utility model relates to a gearbox for a miniature reducing motor. The gearbox comprises a box body and a box cover, wherein a gearbox output shaft is arranged in the box body and is connected with a gear speed shifting mechanism, and the other end of the gear speed shifting mechanism is connected with a motor output shaft; the gear speed shifting mechanism comprises a group of dual gears which are connected with each other in an engaging manner, the dual gears are sleeved on a rotating shaft, and gasket sleeves which are used for locating the dual gears are arranged at the two ends of the rotating shaft; and shaft holes which are used for mounting the rotating shaft are formed in the box body and the box cover, and the two ends of the rotating shaft are directly connected to the shaft holes. Thus, the rotating shaft which is used for mounting the dual gears is directly mounted on the box body and is not fixed by bearings, so that the cost for the bearings is saved, and the mounting is facilitated.
Description
Technical field
The utility model relates to a kind of gear-box, especially a kind of gear-box that is used on the minitype speed reducing motor.
Background technique
In machinery, gearbox applications is very extensive, and its effect is speed change, change speed transmission direction and transmitting torque etc.Multistage duplicate gear is often installed in gear-box inside, and the transmission through duplicate gear comes change speed.Duplicate gear in the existing gear-box is installed on the axle, and the two ends of axle in casing, guarantee gear normal rotation with bearing, bearing with cooperating of casing with key connecting, axle with axle through gear through Bearing Installation.The gear-box that uses on the mahjong machine is because its gear rotational velocity is low, the torque of output is little.Therefore can design a kind of lower-cost gear-box.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned existing technology, and a kind of gear-box that is used on the minitype speed reducing motor is provided, and the gear shift of gear-box inside is simplified, and has saved fabricating cost.
The utility model solves the technological scheme that its technical problem adopts: this gear-box that is used on the minitype speed reducing motor; Comprise casing, case lid, be provided with gearbox output shaft in the casing, gearbox output shaft connects one group of gear shift; The other end of gear shift connects motor output shaft; Wherein gear shift comprises one group of duplicate gear that is connected with a joggle, and duplicate gear is socketed in the rotating shaft, and the two ends of rotating shaft are provided with the gasket sleeve of location duplicate gear; Wherein have the axis hole that is used to install rotating shaft on casing and the case lid, the two ends of its shaft directly are connected on the axis hole.Duplicate gear is socketed in the rotating shaft, and no key connects, and rotating shaft is directly installed in the axis hole on the fixed plate assembly; No bearing fixing; Drive duplicate gear and rotate through relatively rotating between rotating shaft and the axis hole, thereby the installation of having saved key and bearing has reduced the fabricating cost of gear-box.
Its shaft adopts iron-base powder metallurgy material.Between rotating shaft and axis hole, coat lubricant oil, and the rotating shaft of adopting iron-base powder metallurgy material to process there is the effect of selflubricating, makes between rotating shaft and the axis hole and rotate flexibly, reduce friction.
The effect that the utility model is useful is: 1. the rotating shaft that duplicate gear will be installed directly is contained on the casing, and no bearing fixing has been saved the cost of bearing like this, convenient again the installation;
2. the duplicate gear sky is socketed in the rotating shaft, no key connects, and has so not only saved a part but also needn't on gear, axle, process keyway; Also reduce simultaneously the workload of assembling, reduced the fabricating cost of gear-box;
3. duplicate gear forges straight forming with ferrous based powder metallurgical, has exempted from processing cost on the one hand, has improved the wear resistance of part on the other hand again;
4. case lid is structure as a whole and directly is stamped to form, low cost of manufacture.

Fig. 2 is the sectional view on the A-A direction among Fig. 1.
Description of reference numerals: casing 1, case lid 2, axis hole 2-1, gearbox output shaft 3, duplicate gear 4, rotating shaft 5, gasket sleeve 6, motor output shaft 7.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: this gear-box that is used on the minitype speed reducing motor; Comprise casing 1, case lid 2, be provided with gearbox output shaft 3 in the casing 1, gearbox output shaft 3 connects one group of gear shift; The other end of gear shift connects motor output shaft 7; Wherein gear shift comprises one group of duplicate gear that is connected with a joggle 4, and duplicate gear 4 is socketed in the rotating shaft 5, and the two ends of rotating shaft 5 are provided with the gasket sleeve 6 of location duplicate gear 4; Wherein have the axis hole 2-1 that is used to install rotating shaft 5 on casing 1 and the case lid 2, the two ends of its shaft 5 directly are connected on the axis hole 2-1.Wherein duplicate gear 4 adopts iron-base powder metallurgy material to process.Case lid 2 is structure as a whole and directly is stamped to form, low cost of manufacture.
The utility model is simplified existing gear-box; Install simpler; Duplicate gear 4 direct skies are enclosed within the rotating shaft 5, and rotating shaft 5 is directly installed among the axis hole 2-1 on casing 1 and the case lid 2, drive duplicate gear 4 rotations through relatively rotating between rotating shaft 5 and the axis hole 2-1; Thereby saved the installation of bearing, reduced the fabricating cost of gear-box.
Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
