Abstract
The utility model discloses an involute arc gear tooth which comprises a tooth crest arc, a tooth bottom arc and involutes arranged on the two sides and used for transition correction, wherein the tooth width is equal to the tooth height. Arc tooth is a brand new design concept, wherein the tooth width is equal to the tooth height, two arcs have the same diameter, the involutes are arranged on the two sides and used for transition correction, and the moving track of the tooth form is reasonable without the root cutting phenomenon. The transmission operation generates similar rolling friction between circles, which is different from the sliding friction generated by the contact of micro-arc molded surfaces of a common involute gear, thus the friction coefficient is very small, the transmission loss is reduced, and the effects of saving energy and improving the transmission efficiency are realized. The arc does not have a stress point, and the strength is higher so as to transfer a greater torque. The friction coefficient can be reduced by over 50% since the structure is different from a load, and the energy conservation effect is obvious; and particularly, the effect is better that the spiral friction angle of a taper gear is necessarily reduced in order to realize a similar rolling friction effect when an arc bevel gear is adopted in axial cross transmission.
Description
Technical field
The utility model relates to a kind of toothing of gear.
Background technique
In existing gear structure; Its tooth constitutes at the bottom of connecting tooth top and tooth respectively by two involutes; All be plane structure at the bottom of tooth top and the tooth, the linkage structure of plane and curved surface has corner angle, brings resistance to gear transmission; And excessive resistance makes tooth from tooth root portion fracture easily, can't realize that effective transmission influences product working life.Since plane structure be arranged so that the energy that loses in the transmission process is more, energy-saving effect is poor, tooth root portion is prone to stress point and causes damage.
Summary of the invention
Technical purpose of the present invention is to overcome the defective of existing toothing, and a kind of involute circle-arc tooth gear teeth are provided, and running orbit is more reasonable, does not produce to cut the root phenomenon.
Technological scheme provided by the invention does; A kind of involute circle-arc tooth gear teeth; It comprises circular arc at the bottom of tooth top circular arc and the tooth identical with the top circle arc dia, and the tooth top circular arc is provided with the involute transition of revising usefulness with circular arc at the bottom of the tooth and is connected the facewidth and tooth depth equidimension in both sides.
The tooth-shape structure of brand-new design theory; In the transmission operation process, owing to be the arc surface contact, thereby the rolling friction that approaches between circle and the circle produced; Be different from the sliding friction of the differential of the arc shape profile contact generation of common involute gear; So friction factor is very little, and then reduced power transmission loss, to reach effect energy-conservation and the raising transmission efficiency.Be that circular arc does not have stress point at the bottom of the tooth,, can transmit bigger moment of torsion so intensity is higher.
Below in conjunction with description of drawings technological scheme of the present invention.
Description of drawings
Fig. 1 is the structural representation of the involute circle-arc tooth gear teeth of the present invention.
Fig. 2 is an involute circle-arc tooth gear teeth utilization structure schematic representation of the present invention.
Embodiment
In order to understand the present invention, referring to Fig. 1, Fig. 2, a kind of involute circle-arc tooth gear teeth are called for short gradually curved tooth.Gradually curved tooth is different from the gear of conventional involute tooth.What adopt is that circular arc connects and the arc tooth of generation, and the arc tooth that involute is arranged that produces with involute transition correction.
What gradually curved tooth adopted is a kind of brand-new design theory of profile of tooth; Gradually the design proposal of curved tooth employing is: the facewidth equates that with tooth depth tooth top circular arc 1 is identical with the diameter of circular arc at the bottom of the tooth 2, and the both sides of tooth are with involute 3,4 transition corrections; Make the running orbit of profile of tooth more reasonable, do not produce and cut the root phenomenon.Therefore be named gradually curved tooth.
Gradually curved tooth is in the transmission operation process; The arc surface contact; Thereby produce the rolling friction that approaches between circle and the circle, be different from the sliding friction of the differential of the arc shape profile contact generation of common involute gear, so friction factor is very little; And then reduced power transmission loss, to reach effect energy-conservation and the raising transmission efficiency.Gradually curved tooth is that circular arc does not have stress point at the bottom of because of tooth, so intensity is higher, can transmit bigger moment of torsion.
Gradually the friction factor of curved tooth is compared different because of structure and load with conventional involute gear; Can reduce the friction factor more than 50%; Energy-saving effect is fairly obvious, is circle because of curved tooth profile of tooth gradually in the using of the circular-arc bevel gear that particularly when axially intersecting transmission, is adopted, so wants to reach the spiral rubbing angle that must reduce bevel gear near the effect of rolling friction; Thereby friction factor is further reduced, so effect is better.
