Compared with the prior art, the drum-shaped roller type coupler has the advantages of large transmission torque, high operation safety factor, and low production cost.
Description
Technical field
The utility model relates to a kind of drum type roller type coupling, is specifically related to a kind of externality shaft of drum type roller type coupling and the drive mechanism between ring gear.
Background technique
Drum-shaped tooth type shaft coupling is comprised of parts such as the identical externality shaft of two numbers of teeth and flanged ring gears.This coupler structure is compact, transmit motion accurately, reliably, efficiency is high, effectively avoided the sharp corner stress of tooth to concentrate, there is large bearing capacity, reduced the additional load that the various displacements due to axis cause, improved stable working and the reliability of transmission device, be medium-sized and heavy machinery in the parts of modal connection two transmission shafts.It can compensate the augular offset that two joining shafts do not overlap and cause because of axis, allows diaxon to have certain angular deflection.Be specially adapted to low-speed heave-load operating mode, if the industries such as metallurgy, mine, lifting transportation, the axle that is also applicable to all kinds of machineries such as oil, chemical industry, universal machine are transmission.
Although drum-shaped tooth type shaft coupling function admirable, is widely used, exist following not enough: 1, cost of production is high.Main generating process and the gear shaping method of adopting of at present crowned teeth processing, course of working is complicated, and the processing of this form cutting has certain form error, affects the drive characteristic of coupling.In order to obtain more accurate profile of tooth, generally adopt digital control processing, this has further increased the manufacturing expense of coupling.2, exist master and slave moving axis motion to depart from, the potential safety hazard that causes equipment malfunction to be done.Due to long-term in more severe working condition, the drum-shaped tooth type shaft coupling gear teeth may fatigue break far below allowable load in the situation that, the residue gear teeth will be subject to larger impulsive load and may all fracture, forming master and slave moving axis motion departs from, cause equipment generation misoperation, even lead to production accident.
Model utility content
The purpose of this utility model is to provide a kind of and reduces production costs, the drum type roller type coupling of security of operation replace the drum-shaped tooth type shaft coupling of same specification.
This drum type roller type coupling that the utility model provides, include cydariform external tooth axle sleeve and with the ring gear of its engagement.Between described axle sleeve and ring gear, be useful on the roller of transmitting torque.
The profile of described roller is cydariform or cylindrical, and its turning radius equates with the crowning radius of the described cydariform external tooth flank of tooth.
The both sides tooth root of described cydariform external tooth and tooth root and the junction surface between the flank of tooth of the junction surface between the flank of tooth and ring gear internal ring gear are indent drum surface or cylndrical surface, and corresponding indent drum surface or the cylndrical surface of two tooth engagements form respectively the engagement pair of mating with described cydariform and cylindrical rollers profile; It between described roller and engagement pair, is Spielpassung.
Between the cydariform external tooth of the internal ring gear of described ring gear and axle sleeve, take arc surface as surface of contact, the center of circle of arc surface overlaps with the arc surface center of circle of described roller.
The utility model has designed the roller for transmitting torque between axle sleeve and ring gear, can transmit larger moment of torsion, make the internal ring gear requirement on machining accuracy of crowned teeth and ring gear greatly reduce simultaneously, can adopt general machine tooling, do not need special-purpose process equipment; On axle sleeve, all there is arc surface at the tooth root place of cydariform external tooth and ring gear internal ring gear, even if there is fatigue ruption in roller in running, axle sleeve and ring gear can carry out moment of torsion transmission by the engaging of arc surface between the two, guarantee that the motion between master and slave moving axis can not depart from, the production accident of having avoided equipment misoperation to cause.
In sum, the utility model is compared with prior art, has the advantage that transmitting torque is large, operating safety factor is high, cost of production is low.

Embodiment
Preferred embodiment, as shown in Figures 1 to 5, this drum type roller type coupling that the utility model provides, comprises axle sleeve 1, ring gear 2, roller 3, roller baffle plate 4, hinged bolts 5.On axle sleeve 1, there is cydariform external tooth, the internal ring gear of ring gear 2 and its engagement.Between axle sleeve 1 and ring gear 2, pass through roller 3 transmitting torques.The profile of roller 3 adopts cydariform, and its radius equates with the crowning radius of the cydariform external tooth flank of tooth.Tooth root and the junction surface between the flank of tooth of the both sides tooth root of cydariform external tooth and the junction surface between the flank of tooth and ring gear 2 internal ring gears are indent drum surface, the corresponding indent drum surface of two tooth engagements forms the engagement pair of mating with roller 3 profiles, between roller 3 and inside and outside tooth engagement pair, is Spielpassung.Between the cydariform external tooth of the internal ring gear of ring gear 2 and axle sleeve 1, take arc surface as surface of contact, the center of circle of arc surface overlaps with the arc surface center of circle of roller 3.The two ends of ring gear 2 are connected with roller baffle plate 4 by set screw, are used for making roller 3 axial limitings.
During assembling, the axle sleeve 1 of two of left and right with cydariform external tooth is connected by key with master and slave moving axis respectively, between axle sleeve 1 and ring gear 2, by roller 3, transmit motion, respectively and fastening by hinged bolts 5 between two ring gears 2 of axle sleeve 1 engagement, thus realize the motion transmission between master and slave moving axis.
Above-described embodiment is applicable to need to transmit larger moment of torsion, and allow has certain augular offset between the axis of two half-couplings simultaneously.
Embodiment two, the present embodiment is identical with other structure of preferred embodiment, difference structure is: the profile of roller 3 is cylindrical, tooth root and the junction surface between the flank of tooth of the both sides tooth root of cydariform external tooth and the junction surface between the flank of tooth and ring gear 2 internal ring gears are indent cylndrical surface, and the corresponding indent cylndrical surface of two tooth engagements forms the engagement pair of mating with roller 3 profiles.The present embodiment is applicable to need transmitting large torque, requires two half-coupling mounting points without the accurate transmission of misalignment of axe.
