Abstract
The utility model relates to a gear drive idle speed oscillation damping device. A concave surface is arranged on one surface of a frequently-engaged gear; screw holes which are equally divided according to the circumference are formed in the concave surface; gear discs are sleeved by the screw holes and a screw rod at the end part of a guide post screw rod; ellipse holes and spring seats of which the quantities are equal to the quantity of the screw holes are arranged on the gear discs; and a spring is arranged between each spring seat and each guide post, so that the double-sided contact of an input shaft gear and a gear tooth of the frequently-engaged gear in an idle speed state can be effectively eliminated; the input shaft gear and the frequently-engaged gear work under a reverse-free drive gap and the single-side contact between the input shaft gear and the frequently-engaged gear is guaranteed; and therefore, vibration and noise caused by positive and negative engagement of a speed reducer can be avoided when an engine is in the idle speed state. The gear drive idle speed oscillation damping device has the advantages of simple structure, reasonable design, reliable operation and obvious noise reduction effect.
Description
Technical field
The utility model relates to a kind of drive technology, relates in particular to the gear transmission idling vibration damping device that an a kind of gear between two driving gears is equipped with the weakening fluted disc.
Background technique
Gearbox is one of the most representative product in the gear transmission technology, in gear train assembly, there is the wheel running clearance, the wheel running clearance produces greatly vibrations and noise in transmittance process just large, especially just have wheel running clearance and reversing drive gap such as the engagement of the jack shaft constant mesh gear on gearbox input shaft and the countershaft, thereby gearbox countershaft bearings at both ends easily produces vibrations and makes a noise when causing engine idle.
The model utility content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of gear transmission sideshake that can effectively reduce on the impact of gear noiose, and simple in structure, reasonable in design, the obvious gear transmission idling of noise reduction vibration damping device.
The technological method that its use problem that solves the utility model adopts is: a kind of gear transmission idling vibration damping device, comprise constant mesh gear, the one side of this constant mesh gear is provided with concave surface, be provided with screw by circumference equal dividing on the described concave surface, screw sleeve by this screw and guide pillar screw rod end is equipped with fluted disc, described fluted disc is provided with elliptical aperture and the spring seat with above-mentioned screw equal amount, between spring seat and guide pillar spring is housed.
The number of teeth of described constant mesh gear equates with the number of teeth on the fluted disc.
Relative dislocation between the tooth on the tooth of described constant mesh gear and the fluted disc.
The beneficial effects of the utility model are: equate with the constant mesh gear number of teeth in the installation of constant mesh gear end face, the fluted disc of relative dislocation between tooth and the tooth, when constant mesh gear is meshed transmission with input shaft gear, tooth is under spring action on constant mesh gear and the fluted disc, input shaft gear is contacted with the double side of the constant mesh gear gear teeth, input shaft gear and constant mesh gear are worked under without the reversing drive gap, guarantee that input shaft gear contact with constant mesh gear flank of tooth single face all the time, thereby can not cause when making engine idle that the positive and negative engagement of speed changer causes shakes and makes a noise; Have simple in structure, reasonable in design, reliable and the obvious advantage of noise reduction.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 side view.
Among the figure: 1-constant mesh gear, 2-concave surface, 3-screw, 4-guide pillar, 5-fluted disc, 6-spring seat, 7-elliptical aperture, 8-spring, 9-screw rod.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1 and Fig. 2, a kind of gear transmission idling vibration damping device, comprise constant mesh gear 1, the one side of this constant mesh gear 1 is concave surface 2, on concave surface 2, be provided with screw 3 by circumference equal dividing, screw rod 9 by this screw 3 and guide pillar 4 ends is set with fluted disc 5, and described fluted disc 5 is provided with elliptical aperture 7 and the spring seat 6 with above-mentioned screw 3 equal amounts, at spring seat 6 and 4 of guide pillars spring 8 is housed.The number of teeth of above-mentioned constant mesh gear 1 equates with the number of teeth on the fluted disc 5; Relative dislocation between the tooth on the tooth of above-mentioned constant mesh gear 1 and the fluted disc 5.In actual applications, constant mesh gear 1 end installation at the gearbox jack shaft equates with constant mesh gear 1 number of teeth, the fluted disc 5 of relative dislocation between tooth and the tooth, when the constant mesh gear 1 of jack shaft is meshed transmission with input shaft, tooth on the constant mesh gear 1 of jack shaft and the tooth on the fluted disc 5 are under spring 8 effects, the idling mode input shaft gear is contacted with constant mesh gear 1 the effective of gear teeth double side of jack shaft, the constant mesh gear 1 of input shaft gear and jack shaft is worked under without the reversing drive gap, guarantee that input shaft gear contact with constant mesh gear 1 flank of tooth single face of jack shaft all the time, do not shake and make a noise so that can not cause that the positive and negative engagement of speed changer causes during engine idle.The utlity model has simple in structure, reasonable in design, reliable and the obvious advantage of noise reduction.
