Abstract
The utility model discloses an orthogonal conical pendulum type planetary reduction gear, comprising an input axle (8), an output axle (4), a needle wheel (1), a pendulum wire wheel (2) and a rotationarm (3), wherein the rotation arm is connected with the pendulum wire wheel (2) and the output axle is mounted on the rotation arm, characterized in that: a driving cone gear (7) and a driven cone gear (6) are set between the needle wheel and the pendulum wire wheel and the input axle is connected with the driving cone gear and the driving cone gear is geared in the driven cone gear and the driven cone gear and the pendulum wire wheel eccentrically drive and the input axle and the output axle are set in right-angle. The driving cone gear and the driven cone gear 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 cone gear and the driven cone 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 connected with cycloid wheel 13, 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 orthogonal conical pendulm formula 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 orthogonal conical pendulm formula 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, it is characterized in that being provided with between described pinwheel and the cycloid wheel drive bevel gear and by dynamic bevel gear, described input shaft is connected with described drive bevel gear, described drive bevel gear and describedly meshed by dynamic bevel gear, described by dynamic bevel gear and described cycloid wheel eccentric gearing, described input shaft and described output shaft at right angles are provided with; The center of described cycloid wheel is provided with eccentric shaft, and described eccentric shaft is become eccentric gearing with described by dynamic bevel gear.
The utility model increased the master between pinwheel and the cycloid wheel, by dynamic bevel gear after, by its engagement and drive connection, input shaft is through the deceleration of bevel gear, need only the master, changed by the number of teeth of dynamic bevel gear, just bevel gear is changed, just can be realized the variation of any velocity ratio, and its gear range can be selected arbitrarily in the 9-595 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 orthogonal conical pendulm formula planetary reducer, comprise input shaft 8, output shaft 4, pinwheel 1, cycloid wheel 2 and pivoted arm 3, described pivoted arm 3 is connected with described cycloid wheel 2, described output shaft 4 is installed on the described pivoted arm 3, be provided with drive bevel gear 7 between described pinwheel 1 and the cycloid wheel 2 and by dynamic bevel gear 6, described input shaft 8 is connected with described drive bevel gear 7, described drive bevel gear 7 is meshed by dynamic bevel gear 6 with described, described by dynamic bevel gear 6 and described cycloid wheel 2 eccentric gearings, described input shaft 8 at right angles is provided with described output shaft 4; The center of described cycloid wheel 2 is provided with eccentric shaft 5, described eccentric shaft 5 with described by 6 one-tenth eccentric gearings of dynamic bevel gear.When input shaft 8 input power, driving drive bevel gear 7 rotates, drive bevel gear 7 drives is rotated by dynamic bevel gear 6, then being driven cycloid wheel 2 by eccentric shaft 5 by dynamic bevel gear 6 rotates, cycloid wheel 2 drives pivoted arm 3 revolutions, drive output shaft 4 outputs at last, because drive bevel gear 7 is with different by the quantity of dynamic bevel gear 6 awl teeth, and the purpose that realization is slowed down, to change velocity ratio, as long as choose the drive bevel gear of the corresponding awl number of teeth or changed, just can realize changing arbitrarily the purpose of velocity ratio by dynamic bevel gear.
