Abstract
The utility model relates to a gear speed reducing device which has the structure that a plurality of bent shaft type planet shafts are arranged on parallel shaft lines which deviate from an output shaft, a pair of outer meshed gears are arranged between an input shaft and the planet shaft, and a planet wheel is erected on the planet shaft through a planet bearing and output by an inner gear which is meshed with the planet wheel.
Description
The utility model relates to a kind of gear reducer.
Few tooth difference speed reducer of various countries all adopts the centre-crank shaft input mode at present, and promptly input shaft and output shaft are located on the same axis, and input shaft is the structure of bent axle shape.This traditional structure for the low speed rotation of output planetary wheel, must be provided with a cover output mechanism, is post Xiao mechanism at present.The employing of this post Xiao output mechanism, the stressed increase that makes planetary bearing be more than 63%, and the lost of life is original below 1/5th.Cause this speed reducer complex structure, difficult design.Market share is very low.
The purpose of this utility model is that many curved shaft type planet axis of a kind of biasing speed reducer will be provided, and its energy simplified structure reduces planetary shaft strength, improves its life-span, and it can be come into the market in a large number.
The purpose of this utility model is achieved in that departing from output shaft and several curved shaft type planet axis is set on paralleling to the axis.Planet wheel is erected on the planet axis by planetary bearing, by exporting with the internal gear of planet wheel engagement.Cancellation post Xiao output mechanism; Between input shaft and planet axis, establish a pair of external gear pump.
Because model utility has been cancelled output mechanism, planetary shaft strength reduces, and the life-span increases, and structure has also been simplified.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is the utility model embodiment's a tectonic maps.
Among the figure: (1) input shaft, (2) output shaft, (3), planet wheel, (4) planet axis, (5) planetary bearing, (6) internal gear, (7) casing.
The utility model, input shaft (1) drives each planet axis: planet wheel (3) is erected on the planet axis (4) by planetary bearing (5); Internal gear (6) is meshed with planet wheel (3), and is connected with output shaft (2).
The following describes its principle: when input shaft (1) rotates: will drive planet axis (4); Because input shaft (1) equates with the throw of eccentric of planet axis (4), so planet wheel (3) is done translational motion, it can not rotation, so cause internal gear (6) work that meshes with planet wheel (3) to slowly run, exports by output shaft (2) is outside.
The utility model has the advantages that:
1. owing to cancelled output mechanism, the utility model designs simplification, cost. Planetary shaft strength reduces, and the planetary bearing life-span increases.
2. the utility model is because the planet axle, and planetary bearing quantity is many, and load can be shunted, thus can design high-power, the high pulling torque product.
3. the utility model has reduced vibration, noise owing to being provided with the one-level external gear pump; And the method for the available change external gear pump number of teeth reaches different speed reducing ratio.
Claims (1)
1, a kind of gear reducer, this device are provided with several curved shaft type planet axis departing from the paralleling to the axis of output shaft, and input shaft drives planet axis; Planet wheel is erected on the planet axis by planetary bearing; By outwards exporting, it is characterized in that: depart from the paralleling to the axis of output shaft, several curved shaft type planet axis are arranged with the internal gear of planet wheel engagement.
