Abstract
The utility model discloses an improved double swing line gear retarder which can solve the disadvantages of the prior art which has a large starting current and working current, a large working vibration noises, a high temperature, a large abrasion consumption between the gears and a poor working stability. The utility model comprises a shell of the prior retarder, an output axis positioned in one end of the shell, a main transmission axis positioned in the middle part of the shell and a pair of swing planet gear positioned on the eccentric sleeve of the main transmission axis which are respectively meshed with the fixed gear ring on the shell and the bowl tooth of the output axis to finish the gear down transmission from the main transmission axis to the output axis; the improvement of the utility model is that an input axis is provided between the main transmission axis and the driving motor, and the input axis and the main transmission axis adopt the gear down transmission. The utility model has the advantages of low energy consumption, steady and reliable working and long service life.
Description
Technical field
The utility model relates to gear transmission deceleration machinery, refers to a kind of improved double cycloid gear speed reducer particularly.
Background technique
What the double cycloid gear speed reducer adopted is the transmission of interior engagement planet circular tooth gear, and the intensity of circular tooth gear doubles than the intensity of involute gear under the situation of same modulus.When velocity ratio was identical, it was compared with the ordinary gear speed reducer with power, and volume and weight all can reduce 1/3rd to 2/3rds.Thereby the double cycloid gear speed reducer has that bearing capacity height, volume are little, in light weight, simple in structure, processing and plurality of advantages such as easy to maintenance.But in the using process of reality, we find that the input torque of existing double cycloid gear speed reducer acts directly on its main drive shaft.Like this, input speed on the main drive shaft is too high, per minute can reach 1,400 right sides of turning left, also drive the main transmission part planetary pinion high speed rotating that is installed on the main drive shaft eccentric bushing, add equilibrium block and planetary installation can have deviation, thereby make the inrush current of speed reducer and operating current greatly increase, vibration aggravation, noise increase during work, temperature rise is too high, wearing and tearing between gear accelerate, it is big that machine intimate consumption becomes, and the working stability variation has had a strong impact on the working life and the transmission efficiency of speed reducer.
Summary of the invention
The purpose of this utility model will overcome above-mentioned defective exactly, provides a kind of and can reduce significantly that in-fighting, stable working are reliable, the modified model double cycloid gear speed reducer of long service life.
For realizing this purpose, the designed improved double cycloid gear speed reducer of the utility model, comprise the casing of former speed reducer and the main drive shaft that is installed in the output shaft of casing one end and is installed in the casing middle part, eccentric bushing and Balance disc are installed on the stage casing of main drive shaft, by Bearing Installation a pair of planetary pinion that combines as a whole is arranged on the eccentric bushing, one of them planetary pinion is meshed with the gear ring of deciding on being fixed on casing, another planetary pinion is meshed with the bowl gear that is connected in output shaft end, in order to finish the gearing down from the main drive shaft to the output shaft.Its improvements are: also design has an input shaft between the motor of above-mentioned main drive shaft and driving speed reducer, this input shaft is installed in the other end of the casing relative with above-mentioned output shaft, adopt gear reduction to cooperate between input shaft and the main drive shaft, realize the gearing down from the input shaft to the main drive shaft.
The utility model has the advantages that: in the gear range of former double cycloid gear speed reducer, only between former main drive shaft and drive motor, increased the one-level gearing down, just can make the rotation rotating speed of main transmission part such as main drive shaft and planetary pinion mounted thereto significantly reduce, thereby the operational vibration of speed reducer is alleviated, noise can reduce by 2～3 decibels, wearing and tearing between gear teeth face ease up, temperature rise rate descends, it is more steadily reliable that running becomes, all do not have keyway and shear phenomenon when frequent starting and clockwise and anticlockwise operation, operating life significantly promotes.Simultaneously, reduced the internal consumption of speed reducer effectively, required operating current can descend about 20%, and total transmission efficiency can reach more than 90%.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Accompanying drawing is a kind of structural representation of improved double cycloid gear speed reducer.
Embodiment
Speed reducer shown in the figure has a casing that is made of parts such as casing 2 and case lids 7, and an end of casing is equipped with input shaft 13, and the end that input shaft 13 is positioned at casing is provided with a small gear 11.The other end of casing is equipped with output shaft 1, and the end that output shaft 1 is positioned at casing is connected with one bowl of gear 3.The middle part of casing is equipped with main drive shaft 12, and eccentric bushing 8 and Balance disc 9 are installed on the stage casing of main drive shaft 12, when main drive shaft 12 sizes hour also can be made an integral body with eccentric bushing 8 with it.By two rotary arm bearings a pair of cycloid in planet gear that combines as a whole 6,4 is installed on the eccentric bushing 8, one of them planetary pinion 6 is meshed with the ring gear 5 that is fixed between casing 2 and the case lid 7, the bowl gear 3 of another planetary pinion 4 and output shaft 1 end is meshed, to finish from main drive shaft 12 to output shaft 1 gearing down.Main drive shaft 12 is provided with a gearwheel 10 with the end that input shaft 13 is close, gearwheel 10 can be an internal gear, the small gear 11 of it and input shaft 13 ends directly meshes, realizing from input shaft 13 to main drive shaft the most simple and effective gearing down of structure 12, and do not need former speed reducer is done excessive change.The optimum range of velocity ratio is i=2.5～4 between small gear 11 and the gearwheel 10, in this gear range, the rotating speed that input shaft 13 per minutes 1400 change can reduce to per minute 350～560 when being delivered on the main drive shaft 12 to be changeed, under the prerequisite that guarantees aforementioned advantages, this gear range can make the structure of speed reducer do simple more compactly, and cost is more economical.
In the utility model when work,, drive motor drives input shaft 13 high speed rotating, by the engagement fit of small gear 11 and gearwheel 10, make main drive shaft 12 and on main transmission part planetary pinion 6,4 etc. obtain 2.5～4 times one-level and slow down.Pass through the engagement fit of planetary pinion 6 and ring gear 5 again, and the engagement fit of planetary pinion 4 and bowl gear 3, make output shaft 1 obtain double reduction.Because the rotating speed of main transmission part has reduced, therefore the running balance of whole speed reducer is reliable, less energy consumption, and the transmission efficiency height, practical, have purposes widely.
