Abstract
The utility model relates to a foundation parts gear for a mechanical transmission, in particular to an automobile motor drive gear. Different drive gear structures have different running clearance requirements, and side clearance can only be controlled in manufacturing at present, great noise problem still can not be solved. A diad or a triad gear is constituted by a master gear and a tooth gear, the tooth gear is hollowly sleeved on the master gear, a spring and a spring collar are arranged on the outer side of the tooth gear, a spring and two spring control parts are mounted between the tooth gear and the master gear. The utility model greatly decreases gear engagement driving noise, in particular to solve a difficult problem that noise is big when the automobile motor drive gear is driven, and a better social benefit is achieved in an aspect of environmental protection.
Description
(1) technical field:
The utility model relates to machine foundation part driving gear.
(2) background technique:
In the conventional gears transmission, a pair of intermeshed gear is that tight engagement does not have sideshake at the working surface flank of its tooth that is meshed, and at the opposite side non-working surface of this tooth certain sideshake is arranged.Different driving gear structures have different running clearance requirements, for this reason, all are strict in the mill control sideshakes in the past, however, still can't resolve the big difficult problem of noise.In transmission, do the time spent as varying load or negative moment, owing to sideshake is arranged, produce bump, thereby more strengthened noise at gear non-working surface flank.
(3) summary of the invention:
The purpose of this utility model is to address the above problem, and a kind of no sideshake engaging gear that reduces gear transmission noises, easy processing is provided.
The technical solution of the utility model is: no sideshake engaging gear, constitute the diad gear by master gear and auxiliary gear, the auxiliary gear sky is enclosed within on the master gear, and spring and check ring are equipped with in the auxiliary gear outside, and spring and two spring control pieces are housed between auxiliary gear and the master gear; Master gear and two auxiliary gears constitute the triad gear; The spring that installs between auxiliary gear and the master gear can adopt plate shape spring or spiral spring; The spring of auxiliary gear outside device can adopt spirality, waveform or butterfly spring; The spring control piece can adopt backing pin, screw or projection.In processing and when assembling, are by the locating stud positioning and fixing.
The utility model has the advantages that: a gear in a pair of gear pair that intermeshes is replaced by diad gear or triad gear, master gear is born the effect of transmitting torque, auxiliary gear is pressed against on the master gear, spring and two spring control pieces are housed between auxiliary gear and the master gear, when varying load or negative moment generation, under the effect of spring, main two gears of paying are rotated to opposite both direction, promptly eliminated running clearance, reduce the meshed transmission gear noise by a relatively large margin, especially solve the big difficult problem of motor car engine gear transmission noises for a long time, aspect environmental protection, obtained the good social benefit.
(4) description of drawings:
Fig. 1 is the utility model diad structural representation;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is Fig. 1 master gear structural drawing;
Fig. 4 is the utility model triad structural representation;
Fig. 5 adopts spiral spring diad structural representation for the utility model.
(5) embodiment:
Diad does not as shown in Figure 1 have the sideshake engaging gear, constitute by master gear 1 and an auxiliary gear 2, master gear 1 is born the effect of transmitting torque, auxiliary gear 2 skies are enclosed within on master gear 1 shaft shoulder, axial float, wavy spring 4 and check ring 5 are equipped with in auxiliary gear 2 outsides, under the effect of wavy spring 4 auxiliary gear are pressed against on the master gear, and plate shape spring 3 and spring control piece backing pin 7, backing pin 8 are housed between auxiliary gear and the master gear; By locating stud 6 positioning and fixing, consist of one when processing and assembling.When varying load or negative moment generation, main, pair two gears rotate round about, have promptly eliminated running clearance, reach the purpose that reduces noise.Wherein plate shape spring 3 also can adopt helical spring, as shown in Figure 5.
In the gear transmission train, the normal idle pulley that adopts, the utility model idle pulley is the triad gear, as shown in Figure 4, wherein master gear 1 is common idle pulley, and two auxiliary gear 2 skies are enclosed within on master gear 1 shaft shoulder, and wavy spring 4 and check ring 5 are equipped with in auxiliary gear 2 outsides, under the effect of wavy spring 4, auxiliary gear is pressed against on the master gear, plate shape spring 3 and spring control piece backing pin 7, backing pin 8 are housed between auxiliary gear and the master gear; Processing and when assembling be by locating stud 6 positioning and fixing, and two auxiliary gears 2 and master gear 1 combination constitute two groups of diad gears, play " holding " and " opening down " respectively.When this triad gear structure has just been eliminated former whole idle pulley transmission respectively, the sideshake of two gears that are meshed with it.
In the different structure gear, according to the size and the direction of transmitted load or negative moment, adopt the spring and the mounting type of different-stiffness, gear transmission noises is reduced, reach desirable requirement.The utility model can be widely used in various driving gears, especially is used on the motor car engine driving gear, and noise reduction is remarkable, is beneficial to environmental protection.
