Embodiment Construction

[0010] Such as figure 1 As shown, the inner ring of the load-bearing bearing of the new structure is installed on the output shaft, the outer ring of the load-bearing bearing is directly installed on the wall of the box body, the radial dimension of the load-bearing bearing (9) is increased, and the load-bearing capacity is improved. The outer ring of the load-bearing bearing and its mounting flange are an integral part, and it can also be a combination of more than one part.

[0011] Such as figure 1 As shown, the shaft end of the secondary drive frame (7) is externally processed into a drum-shaped spline, and the secondary drive frame (7) and its drum-shaped spline can be one part, or can be composed of more than one part .

[0012] The above list is only an illustration of the present invention, and does not constitute a limitation to the protection scope of the present invention. All designs that are the same as or similar to the present invention belong to the protectio...

Abstract

The invention discloses a speed reducer of a novel transmission structure. The speed reducer comprises a planetary driving frame, a carrying bearing, a box, an output shaft and an elastic buffering pad mounted inside the output shaft. Taking bearing capability and the transmission structure of the speed reducer into consideration, movement and power transmission can be realized better by utilizing the structure, the transmission structure is adjusted, radial size of a bearing (rotating member) can be increased as much as possible, and bearing capability of parts of the speed reducer is improved; the transmission structure is simplified, the number of the parts is reduced, processing techniques of the parts are simplified, and manufacturing cost is saved.

Description

technical field [0001] The invention belongs to the transmission structure technology of a reducer, and in particular relates to a novel gear transmission structure and a bearing installation structure. Background technique [0002] With the development of modern urbanization, concrete mixer truck, as a mobile precast concrete mixing and transportation equipment, has become an indispensable mixing and transportation equipment for urban construction. One of the key components of the concrete mixer truck to drive the tank is the planetary reducer. The output end of the traditional planetary reducer box is made into a support body with a concave hole diameter smaller than Φ200 to install the key bearing parts. The selection of bearings is limited by the size, and only small-sized bearings can be used. Their bearing capacity is low, and it is impossible to choose bearings that can meet the needs of concrete mixer trucks with a large volume (more than 12 cubic meters), which limi...
