Abstract
The utility model discloses a coaxial planetary reduction gear, comprising an input axle (1), an output axle (5), a needle wheel (1), a pendulum wire wheel (2) and a rotation arm (4), wherein the rotation arm is connected with the pendulum wire wheel and the input axle is mounted on the rotation arm and the output axle is coaxial with the input axle, characterized in that a first level driving wheel (8), a first level driven wheel (8) and a second level driving wheel (10), a second level driven wheel (6) are set between the needle wheel and the pendulum wire wheel and the first level driving wheel is connected with the input axle and engaged with the first level driven wheel and the first level driven wheel is engaged with the second level driving wheel and the second level driving wheel is engaged with the second driven wheel and the second driven wheel is eccentrically driven by the pendulum wire wheel. The driving wheel and the driven wheel are set between the needle wheel and the pendulum wire wheel, thus the loading performance is greatly increased and its transmission ratio range is large. If only exchanging the driving wheel and driven wheel, the driven gear, the transmission ratio is changed at will.
Description
Technical field
The utility model relates to a kind of speed reducer, particularly be planetary reducer.
Background technique
The present general involute cylindrical gear Gear Planet Transmission speed reducer that adopts, involute planetary gear gear transmission speed reducer, the cycloid pinwheel planetary gear transmission system speed reducer, their single-stage step-down ratio is all less relatively, realize bigger velocity ratio, just need to adopt the speed reducer of two-stage parallel connection or plural parallel stage, particularly for the cycloid pinwheel planetary gear transmission system speed reducer, be applicable to that generally velocity ratio is greater than 9 situation, as shown in Figure 1, its basic structure is by input shaft 11, output shaft 15, pinwheel 12, cycloid wheel 13 and pivoted arm 14 are formed, described pivoted arm 14 is taken turns with cycloid 13 and is connected, input shaft 11 and output shaft 15 coaxial settings, because the relation of its pinwheel structure, its gear ratio value is odd number, as 9,11,13,15 ... Deng, change its velocity ratio, also only between its odd number, change, velocity ratio to be changed to the ratio of even number or mixed decimal point, can't realize, that is to say, want to change arbitrarily velocity ratio, present cycloid pinwheel planetary gear transmission system speed reducer can't be realized.As seen, present cycloid pinwheel planetary gear transmission system speed reducer, its range of transmission ratio is less, and can't change arbitrarily, can not satisfy the demand in market far away.
The model utility content
In view of the deficiency that background technique exists, the technical problems to be solved in the utility model provides the coaxial-type planetary reducer that a kind of velocity ratio can change arbitrarily.
For this reason, the utility model is realized by the following technical solutions: a kind of coaxial-type planetary reducer, comprise input shaft, output shaft, pinwheel, cycloid wheel and pivoted arm, described pivoted arm is connected with described cycloid wheel, described output shaft is installed on the described pivoted arm, and described output shaft and the coaxial setting of input shaft, it is characterized in that being provided with between described pinwheel and the cycloid wheel one-level driving wheel, one-level driven wheel and secondary driving wheel, the secondary driven wheel, described one-level driving wheel is connected with described input shaft, and with the engagement of described one-level driven wheel, described one-level driven wheel and the engagement of described secondary driving wheel, described secondary driving wheel and the engagement of described secondary driven wheel, described secondary driven wheel and described cycloid wheel eccentric gearing; The center of described cycloid wheel is provided with eccentric shaft, and described eccentric shaft becomes eccentric gearing with described secondary driven wheel.
The utility model is after having increased I and II driving wheel and driven wheel between pinwheel and the cycloid wheel, by its meshing relation, input shaft is through the deceleration of two-stage driving wheel and driven wheel, as long as the two-stage driving wheel and the driven wheel number of teeth are changed, just two-stage driving wheel and driven wheel are changed, just can be realized the variation of any velocity ratio, and its gear range can be selected arbitrarily in the 12.5-3570 scope, its gear range is big, and its bearing capacity improves 20%.
Description of drawings
Further describe relevant details of the present utility model below more in conjunction with the accompanying drawings.
Fig. 1 is the utility model prior art constructions schematic representation;
Fig. 2 is a structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, this coaxial-type planetary reducer, comprise input shaft 7, output shaft 5, pinwheel 1, cycloid wheel 2 and pivoted arm 4, described pivoted arm 4 is connected with described cycloid wheel 2, described output shaft 5 is installed on the described pivoted arm 4, and described output shaft 5 and input shaft 7 coaxial settings, be provided with one-level driving wheel 8 between described pinwheel 1 and the cycloid wheel 2, one-level driven wheel 9 and secondary driving wheel 10, secondary driven wheel 6, described one-level driving wheel 8 is connected with described input shaft 7, and with 9 engagements of described one-level driven wheel, described one-level driven wheel 9 and described secondary driving wheel 10 engagements, described secondary driving wheel 10 and described secondary driven wheel 6 engagements, the center of described cycloid wheel 2 is provided with eccentric shaft 3,6 one-tenth eccentric gearings of described eccentric shaft 3 and described secondary driven wheel.When input shaft 7 input power, driving one-level driving wheel 8 rotates, one-level driving wheel 8 drives one-level driven wheel 9 and rotates, one-level driven wheel 9 drives secondary driving wheel 10 and rotates, secondary driving wheel 10 drives secondary driven wheel 6 and rotates, secondary driven wheel 6 then drives cycloid wheel 2 by eccentric shaft 3 and rotates, the rotation of cycloid wheel 2 drives pivoted arm 4 revolutions, at last by output shaft 5 outputs, because one, the secondary driving wheel is respectively with one, the diameter difference of two driven wheels, and the purpose that realization is slowed down will change velocity ratio, change as long as choose the two-stage driving wheel and the driven wheel of the corresponding number of teeth, just can realize changing arbitrarily the purpose of velocity ratio.
