Abstract
The invention discloses a novel tooth difference speed reducer applicable to various mechanical products which require reducing transmission. Planet gears (4) of the novel tooth difference speed reducer are movably arranged on planet shafts (3) through bearings, the planet shafts (3) are arranged at two ends of a planet carrier (2), an input shaft (1) is arranged in the middle in the planet carrier (2), and an output shaft (7) is fixed in the middle of the right side of a movable gear ring (6) and meshed with a fixed gear ring (5). By means of special small tooth difference transmission adopted by the invention, a plurality of planet gears perform rolling and rotation movement in two gear rings so that a novel one-stage small tooth difference reducing transmission method is formed; simultaneously, a W-shaped mechanism and a parallelogram mechanism in traditional small tooth difference transmission are eliminated, 2-8 planet gears can be used for simultaneous transmission, weight balance is not required, and transmission stresses can be distributed in a balanced manner, so that the service life is greatly prolonged; and the novel tooth difference speed reducer is small in size, light in weight and simple in manufacture process, and manufacture and maintenance costs can be substantially reduced.
Description
Technical field: the present invention relates to be applicable to the various a kind of Novel toothed difference speed reducers that need the engineering goods use of gearing down.
Background technique: traditional all kinds of mechanical reducers.One, dead axle line retarder, its volume are large, during bearing stress is poly-, very easily damage, two, traditional few teeth difference transmission, no matter output is W mechanism, or parallel-crank mechanism, manufacturing process is too complicated, need special-purpose frock, jig and equipment are many, and manufacture cost is high.
Summary of the invention: the invention provides and adopt special few teeth difference transmission, do not need counterweight, can make the transfer force equiblibrium mass distribution, greatly improve working life, significantly reduce a kind of Novel toothed difference speed reducer that manufacture cost and maintenance cost are used.The technological scheme that the present invention adopts for achieving the above object is: its planet wheel 4 is movably arranged on planet axis 3 by bearing, planet axis 3 is arranged on the two ends of planet carrier 2, input shaft 1 is arranged on planet carrier 2 interior middle part, and moving gear ring 6 right side central are output shaft 7 fixedly, and and decides gear ring 5 and mesh.
The invention has the beneficial effects as follows: owing to having adopted special few teeth difference transmission, being done in two gear rings by several planet wheels rolls rotatablely moves, and has formed the novel few teeth difference primary speed-down kind of drive.Cancelled simultaneously W mechanism and parallel-crank mechanism in traditional few teeth difference transmission, planet wheel can adopt 2-8 transmission simultaneously, does not need counterweight, can make the transfer force equiblibrium mass distribution, thereby greatly improve working life.And volume is little, and is lightweight, and manufacturing process is simple, significantly reduced manufacture cost and maintenance cost.
Description of drawings: Fig. 1 is structural representation of the present invention
Embodiment, as shown in Figure 1, its planet wheel 4 is movably arranged on planet axis 3 by bearing, and planet axis 3 is arranged on the two ends of planet carrier 2, and input shaft 1 is arranged on planet carrier 2 interior middle part, and moving gear ring 6 right side central are output shaft 7 fixedly, and and decides gear ring 5 and mesh.
As shown in Figure 1, described moving gear ring 6 is than deciding gear ring more than 5 or few several numbers of teeth.
Working principle of the present invention is: directly drive planet carrier by input shaft and move in a circle, the planet wheel on planet axis, at the volley with decide gear ring, moving gear ring meshes simultaneously.Because the moving gear ring that drives output shaft is Duoed than fixed gear ring or few several numbers of teeth, during one week, moving gear ring is exactly to turn in a week or few motion that has turned several teeth for fixed gear ring more, i.e. few teeth difference transmission in planetary gear revolution.Its drive connection formula is: (the fixed gear ring number of teeth-moving gear ring number of teeth) is divided by the moving gear ring number of teeth.
What of two gear ring numbers of teeth are considered as velocity ratio size and positive and negative then determine.But two gear ring moduluses must be identical, and be consistent with the planet wheel modulus, and adopt the displacement profile of tooth.
Claims (2)
1. Novel toothed difference speed reducer, it is characterized in that planet wheel (4) is movably arranged on planet axis (3) by bearing, planet axis (3) is arranged on the two ends of planet carrier (2), input shaft (1) is arranged on middle part in planet carrier (2), moving gear ring (6) right side central is output shaft (7) fixedly, and and decides gear ring (5) and mesh.
2. a kind of Novel toothed difference speed reducer according to claim 1, is characterized in that described moving gear ring (6) and Duo or few several numbers of teeth than deciding gear ring (5).
