Abstract
The utility model relates to a deceleration transmission device for a large pylome machine, which is used for a mechanism device whose the transmission output position is provided with a large through hole. The utility model makes use of an inner toothed ring plate for conducting a plane motion. The direct drive is provided with an outer toothed wheel with a large through hole for output. The power source can be single or can be inputted via one or more shafts for realizing the stable starting and braking with the high transmitting ratio, high efficient, and high load bearing. The utility model has the advantages of compact structure, convenient manufacture, and convenient maintenance and can be widely side for universal speed reducers by series designs.
Description
The utility model be a kind of constant speed than big speed ratio speed reduction gearing, particularly suitable is in transmission output position has machinery than large through-hole.
The speed reduction gearing that has large through-hole type machinery is so far mainly taked the kinds of drive such as ordinary gear, worm gear, pin tooth or chain belt.When required velocity ratio and carrying were big, this class transmission was not only opened, brakes not steady, and efficient is low, and heavy.Though modern Gear Planet Transmission velocity ratio and bearing capacity can be relatively large,, and can not directly match with the through hole position of equipment because its input shaft and output shaft are in same axis.
The purpose of this utility model is to provide a kind of special retarding transmission device of being convenient to make at the output position large through-hole.A part also can be used for non-large through-hole gearing down.This device performance is better than traditional kind of drive, its utilization internal tooth ring plate is done plane motion, export by the external tooth gear that few direct transmission of the tooth difference theory of engagement can have large through-hole, but power source not only can be single but also bull by one or several eccentric shaft input, realizing big speed ratio, high efficiency, high-mechanic and smooth starting and braking, and the compact structure letter is skilful, manufacturing and easy maintenance.Through Series Design, also can be widely as universal speed reducer.
The simple form of this device as shown in Figure 1, by an output gear shaft (1), a driving cog ring flat-plate (2) and two input eccentric shaft (3) basic building blocks of etc.ing and other associated part formation.Associated part mainly contains bearing (4), casing (5), casing annex, Sealing and coupling etc.Teething-ring plate (2) is sleeved on the gear shaft (1), eccentric shaft (3) and teething-ring plate (2) assembling, and be configured in gear shaft (1) outside.Each axis is parallel to each other.
On Fig. 1 basis, increase the number of eccentric shaft (3), teething-ring plate (2) or gear shaft (1) and associated part bearing (4) thereof etc., can derive from into some kinds of types.Adapt to the large through-hole mechanical equivalent of light feature, increase
(brought forward)
Eccentric shaft number (to 3-5) can make the teething-ring plate running steadily, and availablely imports simultaneously than multi power source; Increase teething-ring plate number (to 2-4), can make the mechanism kinematic balance and strengthen bearing capacity.Sometimes gear shaft (1) also rises to 2-3, forms bull output.
The utility model embodiment, Fig. 2 are two teething-ring plates, three eccentric shaft gearing speed-reducers.Its structure can be made into vertical or horizontal.It has an output gear shaft (1), two driving cog ring flat-plates (2) and three eccentric shaft basic building blocks such as (3).Power can be only from one of them eccentric shaft input, also can import synchronously from two or three eccentric shafts.Not connecting the eccentric shaft extension of power source termination part outside casing can not make, and can make shaft extension yet and be used for assembling break or other control means.
Fig. 3 is similarly the three eccentric shaft transmissions of two teething-ring plates, and the difference of itself and Fig. 2 is that gear shaft (1) increases to 3 (or 2), can export simultaneously.
When adopting two teething-ring plate transmissions, have the eccentric part that two phase differences are 180 ° on each eccentric shaft.When adopting three and four teething-ring plates, have the eccentric part that three and four phase differences are 120 ° and 90 ° on each eccentric shaft.Be that phase difference angle between eccentric part equals the eccentric part number and divides equally 360 °.Eccentric part also can be decomposed with axle, makes to cooperate assembling behind the eccentric bushing again.
Mechanism action of the present utility model is that power is imported by one or several eccentric shaft (3), and driving gear ring flat-plate (2) is done plane motion according to throw of eccentric a, the external tooth engagement output of the internal tooth of teething-ring plate (2) and gear shaft (1).Step-down ratio equals the external tooth number of teeth poor divided by the inside and outside number of teeth, and single-stage driving is usually between the 7.5-125 scope.
This transmission device can be formed multistage transmission by aforesaid single-stage driving string dress; Type can be made into horizontal, vertical, oblique installing type; Shaft extension can be made into structures such as direct-connection type, flange connection type, suit axle type, also can constitute multistage composite structure with other driving mechanism collocation.
Claims (4)
1, a kind of large through-hole mechanical reduction transmission device, it is characterized in that: 1-3 the output gear shaft (1) that can have large through-hole, 1-4 driving cog ring flat-plate (2) and 2-5 input eccentric shaft basic building blocks such as (3) and other associated part constitute, teething-ring plate is sleeved on the gear shaft, eccentric shaft and teething-ring plate assembling also are configured in the gear shaft outside, and each axis is parallel to each other.The eccentric part number is identical with this driving cog ring flat-plate number on each eccentric shaft, phase difference angle between eccentric part equals the eccentric part number and divides equally 360 °, power can be imported from one of them or several eccentric shaft, eccentric shaft driving gear ring flat-plate is done plane motion according to throw of eccentric a, the output that is meshed with the external tooth of gear shaft of the internal tooth of teething-ring plate.
