Abstract

The utility model relates to a planet-gear speed reducer with multiple combined structure types, which is a cylindrical revolving body and has a structure type (a base class) comprising one or two input shafts, one or two output shafts or one inner gear output. The utility model is characterized in that the utility model forms products of various structure types through arrangement and combination and accessories. The speed reducer can be installed and used by fitting for the requirements of parts of a machine. The utility model can be assembled into a base fixed type speed reducer, a speed regulation type speed reducer, a single-stage speed reducer, a two-stage speed reducer, an inner gear fixed type speed reducer, and an output shaft fixed type speed reducer. Thus, the utility model has the characteristics of compact structure, portability and lightness, combined type and convenient application.

Description

Planet-gear speed reducer with multi-combined structure type

The utility model relates to a kind of multiple composite structure type plane table thermoconductivity meter that has.

As everyone knows, present most of retarders such as ordinary transmission gear reducer, cycloidal-pin wheel retarder, worm gear snail skewer gearing speed-reducer, all are a kind of horizontal or vertical speed reducer of unimodality.These retarders are difficult for realizing that multiple composite structure type is to satisfy the needs that install and use at each position of machine.

The utility model has overcome above-mentioned deficiency and has designed, and can be satisfied with each position of machine and install and use and need, and has multiple composite structure type plane table thermoconductivity meter.

The utility model is to utilize retarder is designed to cylindric solid of rotation, has one or two input shafts, and the structure type of or two output shafts or an internal gear output is by permutation and combination and mix accessory and form structural type miscellaneous.It is suitable at the needs at each position of machine application being installed, and promptly can be assembled into base-fixed retarder, also can be assembled into the speed adjusting type retarder; Promptly can be assembled into single reduction gear, also can be assembled into double reduction gear; Promptly can be assembled into the fixing retarder of internal gear, also can be assembled into the fixing retarder of output shaft.

The utility model and existing retarder technology relatively have following characteristics:

1, the function that has the composite structure type.Because retarder itself is to be designed to cylindric solid of rotation, so realize the function of multiple composite structure type as long as mix the form of horizontal base or vertical base and change input output.

2, compact structure, volume are little, in light weight.Owing to adopt the planetary pinion transmission, thus with common cylinder gear reducer ratio with power, volume and weight can reduce 1/3--1/2.

3, gear range is big.Owing to adopt the planetary pinion transmission, so a stage gear ratio is 10-100; Two stage gear ratios are 100-10000.

4, the part kind of retarder is few.Owing to be to be the retarder that basic model and permutation and combination become with rotational-like, so the part kind is few, easily tissue is produced in batches and supporting application.

In a word, compact structure, flexibly light and handy, composite type, using conveniently is characteristics of the present utility model.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is a fundamental diagram of the present utility model.In the drawings, eccentric shaft (pivoted arm) the 1st, input shaft, because its rotation is subjected to the restriction of internal gear 2, planet wheel 3 is done plane motion, just planet wheel 3 was both done the circumference translational motion around stationary axle, also did rotation motion around self axis, because the axis of output shaft is fixed, therefore must pass to output shaft 5 to back rotation by output mechanism 4, realize slowing down.

Fig. 2 is an outline drawing of the present utility model, this retarder profile such as cylindric solid of rotation as seen from the figure, in the drawings, 1 is input shaft (the two ends shaft extension all can be provided with input shaft on demand), 2 are internal gear (also can be used for output), and 5 are output shaft (two end axles all can be provided with output shaft on demand).

Claims

1, a kind of have a multiple composite structure type plane table thermoconductivity meter, it is characterized in that this retarder is cylindric solid of rotation, have one or two input shafts, one or two output shafts or an internal gear output are by permutation and combination and mix accessory to form various structure types.It promptly can be assembled into base-fixed, also can be assembled into speed adjusting type, promptly can be assembled into single-stage, also can be assembled into two-stage; It is fixed promptly to can be assembled into internal gear, and it is fixed also to can be assembled into output shaft.

2, according to claim 1 have a multiple composite structure type plane table thermoconductivity meter, it is characterized in that cylindric revolution system is formed by the planetary pinion drive structure.
