Summary of the invention
The purpose of this utility model provides a kind of advantage that can keep above-mentioned prior art, can overcome its deficiency again, have the transmission balance, velocity ratio is big, mechanical efficiency is high, can self-locking etc. characteristics, and planet creeping type retarder simple in structure, that volume is little.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of planet creeping type retarder mainly is made of input shaft, sprocket wheel, planet axis, planetary pinion, ring gear and output shaft, it is characterized in that:
A. a double-crank that mainly is made of input shaft, planet axis and two sprocket wheels drives the parallelogram input systems, two sprocket wheels are fixed on respectively on input shaft and the planet axis, input shaft and planet axis are equipped with the eccentric shaft part that throw of eccentric is e, its eccentric shaft part links by bearing pair and planetary pinion, input shaft and planet axis two ends all by Bearing Installation on left and right side plate;
B. output system that mainly constitutes by left and right side plate and output shaft, the wheel rim of left and right side plate is installed in the chute that is made of housing and left and right cover plate, and output shaft is fixed on the left sideboard;
C. planet that mainly is made of ring gear and planetary pinion is counter pushes away engagement systems in the creeping type, and ring gear and housing are fixedly connected, and are meshed with planetary pinion.
Double-crank described in the utility model drives except that adopting chain wheel drive, also can adopt gear drive or belt pulley to drive.
Characteristics of the present utility model are:
1. velocity ratio is big, the mechanical efficiency height, and output speed is relatively stable.According to velocity ratio formula i=Z
2/ Z
2-Z
1, the velocity ratio of this machine is consistent with standard " planetary speed reducer with small tooth number difference "; Because this retarder has adopted the anti-engagement systems in the creeping type that pushes away, the between cog friction is little, and its mechanical efficiency is higher than the present conventional worm type of reduction gearing that uses far away; This retarder directly obtains output movement by the anti-creeping type engagement systems that pushes away, and has replaced the pin output system of existing " planetary speed reducer with small tooth number difference ", and the instantaneous speed fluctuation is very little.
2. possesses auto-lock function.
3. import, export coaxial, be convenient to install and debugging.
4. simple in structure, compact, easy to assembly, be convenient to realize standardization, producing in serial form.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1-input shaft, 2-sprocket wheel, 3-chain, 4-sprocket wheel, 5-right end cap, 6-right sideboard, 7-planet axis, 8-planetary pinion, 9-ring gear, 10-housing, 11-left sideboard, 12-bearing, 13-left end cap, 14-output shaft, A-ring gear Pitch radius, e-throw of eccentric, ω
1-input shaft angular velocity, ω
2The angular velocity of-planet wheel rotation.
Embodiment
As shown in the figure, planet creeping type retarder is mainly by input shaft 1, sprocket wheel 2,4, planet axis 7, planetary pinion 8, parts such as ring gear 9 and output shaft 14 constitute, and wherein constitute double-crank by parts such as input shaft 1, planet axis 7, sprocket wheels 2,4 and drive the parallelogram input system, sprocket wheel 2,4 is fixed on respectively on input shaft 1 and the planet axis 7, and its effect is to make input shaft 1 and planet axis 8 obtain synchronous rotatablely moving (described double-crank drives and also can adopt gear drive or belt pulley to drive).Input shaft 1 and planet axis 7 are equipped with the eccentric shaft part that throw of eccentric is e, its eccentric shaft part (adopts sliding bearing pair or needle bearing pair by bearing pair, under the situation of installation dimension permission, also can adopt ball bearing) link with planetary pinion 8, input shaft 1 and planet axis 7 two ends all are installed on left sideboard 11 and the right sideboard 6 by ball bearing.
Constitute output system by parts such as left sideboard 11, right sideboard 6 and output shafts 14, the wheel rim of left and right side plate 11,6 is installed on by in housing 10 and left and right end cap 13,5 chutes that constituted, can in chute, rotate, output shaft 14 is fixed on the left sideboard 11, and the rotation of left and right side plate is the output movement of output shaft.
Be made of parts such as ring gear 9 and planetary pinions 8 that planet is counter to push away engagement systems in the creeping type, ring gear 9 and housing 10 are fixedly connected, and are meshed with planetary pinion 8 all the time.Because planetary pinion 8 does not almost have slide relative with ring gear 9 in engagement process, overlap coefficient is big, and stress is good, so profile of tooth can be unrestricted, involute profile, cycloidal tooth profile, arc toothed, triangle profile of tooth etc. all can be selected.The number of teeth and tooth difference also have bigger choice.
The pass of the velocity ratio of the present utility model and the gear number of teeth is: i=Z
2/ Z
2-Z
1(in the formula: Z
1-planet wheel the number of teeth; Z
2-ring gear the number of teeth)
In actual the use, when driven by motor input shaft 1 with ω
1Angular velocity when rotation, through sprocket wheel 2,4, chain 3 drives planet axis 7 and rotatablely moves synchronously, and because of the eccentric shaft part of planetary pinion 8 by sliding bearing pair and input shaft 1 and planet axis 7 links, it is that radius, linear velocity are ω with e that the rotation of input shaft 1 will drive planetary pinion 8 works
1The circumferential plane of e sieves, planetary pinion 8 is meshed with ring gear 9 on being fixed in housing 10, under the effect of reaction thrust, force planetary pinion 8 to do reverse rotatablely moving in " wriggling " mode, this motion of planetary pinion 8, drive left sideboard 11 and right sideboard 6 rotations via planet axis 7,, promptly formed the output movement of output shaft because of output shaft 14 is fixed on the left sideboard 11.
The reaction force that this system motion produced can be offset by two gimbals that are installed on the input shaft 1.Inject lubricant oil in housing 10, the lubricated of gear engagement pair and sliding bearing pair can be solved by the splash lubrication mode, the lubricated employing of left and right side plate outer rim in chute is lubricated naturally, can drive oil groove on outer rim.
The utility model is except that being done the output movement by the moving output shaft of left and right side plate rotating band, in particular cases, also can utilize the frame output movement that connects firmly with ring gear (as winch cylinder, lifting with electric wire hoist etc.).
