Abstract
The invention discloses a noise reduction chuck for eliminating a gear clearance, which comprises a first metal chuck and a second metal chuck, wherein a connecting rubber body is arranged between the first metal chuck and the second metal chuck; the first metal chuck and the second metal chuck are fixedly connected with the connecting rubber body; and an included angle is arranged between central lines of the first metal chuck and the second metal chuck. According to the noise reduction chuck, the included angle between the two metal chucks is eliminated after mounted in an assembly; the purposes of eliminating the clearance and reducing noise are exerted by a torque generated by a reactive force of the rubber body; the noise reduction chuck is simple in structure and convenient to fabricate; the noise of an engine can be reduced greatly; the service life of a product is prolonged greatly; and a driving comfort level is raised.
Description
Technical field
The present invention relates to a kind of accessory for reducing engine noise, in particular a kind of for the noise reduction chuck of eliminating gear clearance.
Background technique
The driving prerequisite of Hyundai Motor must low-carbon environment-friendly, the enjoyment of driving depends on that the travelling comfort of automobile itself and noise are to the influence of driver, Chang Tuyunshu heavy truck particularly, its horsepower is big, and the moment of torsion that is in operation is big, time for a long time, certainly will cause the gap between each gear to increase, when speed changes, when engine speed changes simultaneously, the noise of motor increases, and has a strong impact on driving safety.The present crack that disappears, noise reduction technology is still blank, among truck particularly heavily blocks, the main still power that people pay close attention to, the powerful noise less relevance of sending for motor, particularly cause the increase in gap owing to the wearing and tearing of gearbox middle gear, the noise of the similar bump that produces when engine speed changes is downplayed equally, the manufacturing of conventional engine, mainly be that the mode of the machining accuracy by improving each component reduces the gap and reaches the purpose that reduces noise, but the gap that can't avoid the wearing and tearing between each part and produce is at the abnormal sound that moves and produce when changing mutually.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and effectively reduced gear clearance for the noise reduction chuck of eliminating gear clearance, reduce noise.
The present invention is achieved by the following technical solutions, the present invention includes the first metal chuck and the second metal chuck, be provided with the connection rubber body between the described first metal chuck and the second metal chuck, the first metal chuck and the second metal chuck with to be connected rubber body fixedly connected, are provided with angle between the center line of the first metal chuck and the second metal chuck respectively.
Described angle is 1～2 °.The size of angle directly influences the working life of product and the crack that disappears, noise reduction, because the motor surrounding environment is abominable, the connection rubber body in the chuck is followed the working life of motor, is in twisted state throughout one's life, and is excessive as angle, and certainly will reduce working life; But angle is too small, by producing needed moment of torsion, not have the purpose of crack, noise reduction of disappearing.
As one of optimal way of the present invention, described angle is 1.35 °.
Offer respectively be used to the draw-in groove that is connected on the described first metal chuck and the second metal chuck, draw-in groove is connected two metal chucks on the gear.
Be respectively equipped with diamond coated layer on the described first metal chuck and the second metal chuck, guarantee the wear resistance of high strength, high tenacity and the surface of contact at draw-in groove place.
The present invention has the following advantages compared to existing technology: the present invention is making the angle between two metal chucks eliminate behind the assembly of packing into, the moment of torsion that produces under the reaction force of rubber body plays the purpose of the gap that disappears, noise reduction sound, simple in structure, easy to make, can greatly reduce engine noise, prolong the working life of product greatly, improve the comfort level of driving.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below embodiments of the invention are elaborated, present embodiment is being to implement under the prerequisite with the technical solution of the present invention, provided detailed mode of execution and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As depicted in figs. 1 and 2, present embodiment comprises the first metal chuck 1 and the second metal chuck 2, be provided with between the described first metal chuck 1 and the second metal chuck 2 and connect rubber body 3, the first metal chuck 1 and the second metal chuck 2 with to be connected rubber body 3 fixedly connected, are provided with angle α between the center line of the first metal chuck 1 and the second metal chuck 2 respectively.
The size of angle α directly influences the working life of product and the crack that disappears, noise reduction, because the motor surrounding environment is abominable, the connection rubber body 3 in the chuck is followed the working life of motor, is in twisted state throughout one's life, α is excessive as angle, and certainly will reduce working life; But angle α is too small, by producing needed moment of torsion, not have the purpose of crack, noise reduction of disappearing.Therefore the angle α of present embodiment is 1.35 °
Offer respectively be used to the draw-in groove 4 that is connected on the first metal chuck 1 and the second metal chuck 2, draw-in groove 4 is connected two metal chucks on the gear.Be respectively equipped with diamond coated layer on the first metal chuck 1 and the second metal chuck 2, the first metal chuck 1 and the second metal chuck 2 adopt 40Cr Hardened And Tempered Steel to make, can select other materials for use among other embodiments, only need the wear resistance of high strength, high tenacity and the surface of contact at assurance draw-in groove 4 places.
Motor is in when work, and the noise in the working room mainly is by the silencing apparatus noise reduction, and it is when being delivered to each operation interval with moment of torsion by gearbox, can eliminate gap between each part rapidly by the big moment of torsion of chuck, reaches the purpose of noise reduction.
