Abstract
This invention discloses a ring gear rotating/counter rotating unit in which the ring gear collar and the ring gear slot is ring noncircular mounted int he rotating wheel, drive wheel, driven wheel, planetary wheel, central wheel and guidance wheel are all mounted on the planetary frame fixed in a retaining bracket by balls. When the central wheel turns back with steady rotation, the drive wheel turns back around the ring gear collar, if the guidance wheel and drive wheel are at the ring noncircular slot, then the planetary frame will rotate around the retaining bracket and the wheel will rotate back with variable speed reaching rotate/counter rotate periodically.
Description
The present invention relates to a kind of annular teeth type positive and negative rotational mechanism, especially be installed in the periodicity of positive and negative runner, no switching type annular teeth type positive and negative rotational mechanism.
Positive and negative rotational mechanism is the key and the core component of long stroke pumping unit, because present domestic maturation, reliable, practical positive and negative rotational mechanism are few, thereby influences the popularization of long stroke pumping unit.From the data of seeing, positive and negative rotational mechanism mainly contains three classes: 1, hydraulic pressure clockwise and anticlockwise, and the product of French MaPe company, its power system configuration is simple, and it is also light conduct oneself with dignity, but efficient is low, and the life-span lacks, and is less economical.2, motor positive and inverse, it is to utilize the rotation direction of control motor to reach the purpose of controlling the clockwise and anticlockwise of taking turns, poor reliability when this mechanism's commutation is switched.3, mechanical clockwise and anticlockwise, this is present domestic research, manufactures experimently a more class switching type positive and negative rotational mechanism, is the simplest a kind of switching mode, but impact when switching bigger, the rate of fault height, the life-span is short.
The object of the present invention is to provide a kind of no switching type annular teeth type positive and negative rotational mechanism, reversing impact when it can prevent clockwise and anticlockwise effectively.
The object of the present invention is achieved like this; Planet carrier rotates around fixed base by ball, and central gear and planet wheel are hinged on respectively on the planet carrier, and planet carrier is connected with revolute pair with driving wheel with mutually affixed follower.Central gear is meshed with planet wheel, and planet wheel is meshed with follower, and driving wheel is meshed with annular tooth ring on the positive and negative runner, and planet carrier is positioned at annular tooth ring recess on the annular tooth ring with the hinged guide wheel of revolute pair.Like this, when central gear isogonism when revolution speed, driving wheel turns round around annular tooth ring, is positioned at the circular arc portion of annular tooth race as guide wheel, and then drive wheel annular tooth ring and clockwise and anticlockwise crop rotation constant speed are turned round.Be positioned at annular non-knuckle-tooth slot part as guide wheel and driving wheel, then planet carrier will rotate around fixed base, annular tooth circle and the revolution of clockwise and anticlockwise crop rotation speed change.
The present invention is because adopt annular tooth ring, and non-knuckle-tooth groove planet rotates, so the requirement of property performance period clockwise and anticlockwise and can overcome reversing impact easily.
The present invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is a transmission schematic representation of the present invention.
Among the figure, (1) planet carrier; (2) central gear; (3) guide wheel; (4) planet carrier; (5) ball; (6) follower; (7) driving wheel; (8) annular tooth race; (9) annular tooth ring; (10) positive and negative runner; (11) fixed base; (12) annular non-knuckle-tooth groove.
Among the embodiment shown in the figure, around fixed base (11) rotation, center (2) and planet wheel (4) are hinged on respectively on the planet carrier (1) planet carrier (1) by ball (5).Planet carrier (1) is connected with revolute pair with driving wheel (7) with mutually affixed follower (6).Central gear (2) is meshed with planet wheel (4), planet wheel (4) is meshed with follower (6), driving wheel (7) is gone up affixed annular tooth ring (9) with positive and negative runner (10) and is meshed, and planet carrier (1) is positioned at annular tooth ring recess (8) with the hinged guide wheel of revolute pair (3).Like this, when central gear (2) constant speed was turned round, driving wheel (7) was around annular tooth ring (9), was positioned at the circular arc portion of annular tooth race (8) as guide wheel (3), and then driving wheel (7) driving ring shaped ring gear (9) is done the constant speed revolution with positive and negative runner (10).Be positioned at annular non-knuckle-tooth groove (12) part as guide wheel (3) and driving wheel (7), then planet carrier (1) will rotate around fixed base (11).Annular tooth ring (9) and positive and negative runner (10) are done the speed change revolution.Reach the periodically purpose of clockwise and anticlockwise.
