Abstract
The utility model discloses a planetary driving type internal gear output structure which comprises an input gear, a planet wheel shaft, an expansion sleeve and a pressing plate, wherein the shaft end of the planet wheel shaft is connected in the inner ring of the input gear through the expansion sleeve, the connection end face is tightly pressed by the pressing plate, a bearing is sleeved on the planet wheel shaft, and the bearing is assembled in a bearing hole of a planet carrier matched with the planet wheel shaft. The planetary driving type internal gear output structure is simple. External teeth of the input gear can be assembled freely, the number of the teeth only needs to meet the requirements of the transmission ratio, the adjacency condition and the concentric condition, and the assembling requirements do not need to be met. The assembling and machining method is simple. The planetary driving type internal gear output structure can be widely used for speed reducers, speed increasers, differential mechanisms, reversing gears and the like to reduce machining cost.
Description
Technical field
The utility model relates to a kind of planetary pinion transmission, is specifically related to a kind of internal gear export structure of Gear Planet Transmission.
Background technique
The planetary pinion transmission is one novel, type of belt drive efficiently, compare with the ordinary gear transmission, when they part material and homogeneous phases such as mechanical property, accuracy of manufacturing, operating conditions simultaneously, have characteristics such as volume is little, in light weight, gear range is big, bearing capacity is high, the life-span is long, widely applicable, therefore it is often used as retarder, speed increaser, differential mechanism and changement and other specific use, can be satisfied with multiple different operating conditions.But each tooth number of Gear Planet Transmission can not arbitrarily be chosen, and must satisfy in abutting connection with condition, concentric condition and assembly condition according to the characteristics of Gear Planet Transmission, just can carry out normal transmission, so Gear Planet Transmission is subjected to the restriction of correlated condition and fails to be used widely.Generally speaking, planetary output shaft all adopts key to connect, adding that the center line that requires keyway man-hour is wanted and the fixing center line place planes overlapping of teeth groove, if error just may cause gear to assemble, make troubles to manufacturing and assembling, also can increase certain manufacture cost because of its special requirement, and the bearing hole on the end cap and the hole on the casing there are the coaxality requirement, and require to make up processing, also can increase manufacture cost.
The model utility content
The model utility purpose: the purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of internal gear export structure that assembles the simple Gear Planet Transmission of mode is provided.
Technological scheme: the internal gear export structure of a kind of Gear Planet Transmission described in the utility model, comprise input gear, planet wheel shaft, swelling cover and pressing plate, the axle head of described planet wheel shaft is bound up in the interior ring of described input gear by described swelling cover, described connection end face is compressed by described pressing plate, input gear and planet wheel shaft are connected by key and change the connection of swelling cover into, not only be convenient to assembling, and need not to process keyway, can reduce the processing cost of planet wheel shaft.
Further, be with bearing on the described planet wheel shaft, described bearing is assemblied in the bearing hole with the suitable planet carrier of described planet wheel shaft, add the bearing hole that only needs man-hour planet carrier and carry out bore hole processing, need not to make up processing with bearing support, reduce processing cost, and saved the axial dimension that is used for bearing support originally.
Beneficial effect: the utility model is simple in structure, the external tooth of input gear can arbitrarily be joined tooth, the number of teeth only need satisfy velocity ratio, get final product in abutting connection with condition and concentric condition, need not to satisfy assembly condition, and assembling and processing method are simple, can be widely used in retarder, speed increaser, differential mechanism and changement etc., cut down finished cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
Embodiment:The internal gear export structure of a kind of Gear Planet Transmission of the utility model, as shown in Figure 1, comprise input gear 3, planet wheel shaft 1, swelling cover 4 and pressing plate 5, the axle head of planet wheel shaft 1 is bound up in the interior ring of input gear 3 by swelling cover 4, connecting end face is compressed by pressing plate 5, be with bearing on the planet wheel shaft 1, bearing is assemblied in the bearing hole with the suitable planet carrier 2 of planet wheel shaft 1.
Input gear 3 and planet wheel shaft 1 are connected by key and change swelling cover 4 into and connect, and not only are convenient to assemble, and need not to process keyway, can reduce the processing cost of planet wheel shaft 1; Add the bearing hole that only needs man-hour planet carrier 2 and carry out bore hole processing, need not to make up processing with the bearing support of bearing, reduced processing cost, and saved the axial dimension that is used for bearing support originally.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
