Abstract
The utility model discloses a high-speed-ratio tooth difference transmission suitable for speed reduction transmission of mechanical products of various specifications and types. Planet wheels (4) are movably arranged on planet shafts (3) through bearings. The planet shafts (3) are arranged at the two ends of a planet frame (2). An input shaft (1) is arranged in the middle in the planet frame (2). An output shaft (7) is fixed to the middle of the right side of a movable gear ring (6), and the movable gear ring (6) is meshed with a fixed gear ring (5). Sun wheels (8) are arranged in the middle of the input shaft (1) and meshed with the planet wheels (4). As the special small tooth difference transmission is adopted, a plurality of the planet wheels roll and rotate in the two gear rings, and a novel small tooth difference one-level speed reduction transmission mode is formed. The transmission speed ratio is large, and the speed ratio can be matched with the range of 60-500 at will. Balance weights are not needed, transmission stress can be distributed in a balanced mode, and therefore the service life is greatly prolonged. The high-speed-ratio tooth difference transmission is small in size, light in weight and simple in manufacturing process, and lowers the manufacturing cost and the maintaining cost greatly.
Description
Technical field: the utility model relates to a kind of poor speed changer of large speed ratio tooth that all size type engineering goods need gearing down to use that is applicable to.
Background technique: traditional hoist electric wire hoist is the transmission device of three grades of deceleration external tooth engagements of dead axle line, and its shortcoming is that volume is large, during when carrying, stress gathers, very easily damages.The 2nd, manufacturing process is complicated, needs the special tooling of use, and equipment is many, and manufacture cost is high.
Model utility content: the utility model provides a kind of special few teeth difference transmission that adopts, and has increased sun gear, can make transmission speed ratio strengthen, and speed ratio can be by the 60-500 left and right poor speed changer of large speed ratio tooth that collocation is used arbitrarily.The technological scheme that the utility model adopted is for achieving the above object: its planet wheel 4 is movably arranged in planet axis 3 by bearing, planet axis 3 is arranged on the two ends of planet carrier 2, input shaft 1 is arranged on the interior middle part of planet carrier 2, moving gear ring 6 right side central are output shaft 7 fixedly, and and determine gear ring 5 and mesh, sun gear 8 is arranged at input shaft 1 middle part, and meshes with planet wheel 4.
The beneficial effects of the utility model are: (1) becomes rotation axis transmission from the transmission of dead axle line gear, from outer gearing, becomes interior engagement, make more equiblibrium mass distribution of transfer force, have greatly improved working life.
(2) increased sun gear, transmission speed ratio is strengthened, speed ratio can be by the collocation arbitrarily of 60-500 left and right.
(3) sun gear is directly installed between the poor drive area of tooth and meshes with planet wheel, thereby realized one-level, secondary slows down simultaneously.Planet wheel and planet carrier rotating speed are reduced, thereby also reduced the oil temperature in casing, improve transmission environment.
(4) volume is little, lightweight, and manufacturing process is simple.Manufacture and maintenance cost have been reduced.
(5) this retarder is arranged on to reel the inside and is arranged on one end with motor, also can make input, output shaft and binding site size energy and traditional product are in full accord, without other sizes of change, can support the use with legacy equipment.
Accompanying drawing explanation: Fig. 1 is structural representation of the present utility model
Embodiment, as shown in Figure 1, its planet wheel 4 is movably arranged in planet axis 3 by bearing, planet axis 3 is arranged on the two ends of planet carrier 2, input shaft 1 is arranged on the interior middle part of planet carrier 2, and moving gear ring 6 right side central are output shaft 7 fixedly, and and determine gear ring 5 and mesh, sun gear 8 is arranged at input shaft 1 middle part, and meshes with planet wheel 4.
As shown in Figure 1, described moving gear ring 6 is than determining gear ring more than 5 or few several numbers of teeth.
Working principle of the present utility model is: by high speed input shaft, drive sun gear to reach two or three planet wheels and do planetary motion, drive planet axis to make planet carrier do synchronous low quick-action simultaneously and turn, the planet wheel being now arranged on planet carrier meshes with fixed gear ring and moving gear ring again simultaneously.Because moving gear ring is for the fixedly many several teeth of ring gear or less several teeth, in planetary gear revolution in the time of one week, moving gear ring is exactly few motion that has turned or turned more several teeth in a week for fixed gear ring, be few teeth difference transmission, drive connection formula: (the fixed gear ring number of teeth---the moving gear ring number of teeth) is divided by the moving gear ring number of teeth.Two gear ring tooth quantities, are considered as velocity ratio size.And determine and export clockwise and anticlockwise.But the modulus of two gear rings must be identical, and be consistent with planet wheel sun gear modulus, and adopt displacement profile of tooth.
Claims (2)
1. the poor speed changer of large speed ratio tooth, comprise that planet wheel (4) is movably arranged in 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 determine gear ring (5) engagement, it is characterized in that sun gear (8) is arranged in the middle part of input shaft (1), and mesh with planet wheel (4).
2. the poor speed changer of large speed ratio tooth according to claim 1, is characterized in that described moving gear ring (6) than to determine gear ring (5) many or lack several numbers of teeth.
