Abstract
The utility model discloses a sleeve-type coupling used for an improved straight wire drawing machine, which comprises a driving wheel connected with a motor shaft and a driven wheel connected with a rotating shaft, wherein a driving part of the driving wheel is sleeve-shaped; a driving part of the driven wheel is cylindrical; the cylindrical driving part is matched and sleeved in the sleeve-shaped driving part; semicircular grooves are uniformly distributed on the axial outer periphery of the driving part of the driven wheel and on the axial inner periphery of the driving part of the driving wheel at intervals; every two semicircular grooves are opposite to form a cylindrical groove; an elastic pin is respectively matched and sleeved in each cylindrical groove; and the elastic pin is parallel to the axis of the driven wheel. The utility model has simple structure and stable torque transmission, can bear larger shearing force and can ensure the coupling to be normally used for a long time.
Description
Technical field
The utility model belongs to the improvement of elastic dowel pin shaft coupling structure, particularly a kind of improved dead-beat drawing machine case butt coupling.
Background technology
The dead-beat drawing machine is the steel wire drawing equipment of using always, and it has, and equipment is simple to operate, cost is lower, be easy to characteristics such as maintenance.Generally be combined into the continous way drawing machine by the monomer drawing machine and use, common have four to connect and pull out, six connect and pull out etc.Each monomer drawing machine is made of critical pieces such as main motor, shaft coupling, mainframe box, drawing tank body, mold box, casings.Wherein shaft coupling is the vitals that connects main motor and mainframe box, require its have stable drive reliable, characteristics such as be easy to safeguard, maintenance cost is low.
What former dead-beat drawing machine shaft coupling adopted is the elastic dowel pin shaft coupling of standard, and the invar silk needs bigger pulling capacity in drawing process, and its shaft coupling will bear bigger twisting resistance, and the nylon pin in the shaft coupling also will bear bigger shearing force.In actual production process, the cut fault of nylon pin of shaft coupling often takes place, cause moment transmission inefficacy or unstability, except causing the shaft coupling damage, under stressed jiggly state, also can make main motor shaft and the flexural deformation of mainframe box high speed shaft, thereby equipment fault point is further enlarged, produce even more serious consequence.The large percentage that this type of accident accounts in the drawing machine accident, and, do not get rid of the root of accident owing to be type selecting and design defect, then can't fundamentally be taken on a new look.
Summary of the invention
The purpose of this utility model is to provide a kind of improved dead-beat drawing machine case butt coupling, and it is simple in structure, can carry bigger shearing force, and the moment transmission is steady, guarantees long-time normal use of shaft coupling.
The purpose of this utility model is achieved in that a kind of improved dead-beat drawing machine case butt coupling, comprise driving wheel that links to each other with motor shaft and the driven pulley that links to each other with rotating shaft, the driving section of driving wheel is sleeve shaped, the driving section of driven pulley is cylindrical, cylindrical driving section engage sleeves is contained in the sleeve shaped driving section, semi-circular recesses is being set respectively on the axial periphery edge of driven pulley driving section and on the axial inner peripheral in the driving wheel driving section uniformly at intervals, semi-circular recesses constitutes cylinder shape groove in twos relatively, cooperate suit spring column pin in each cylinder shape groove respectively, spring column pin parallels with the axis of driven pulley.
Said spring column pin is nylon rod or rod pin, and the number of spring column pin is 8.
Shaft coupling of the present utility model has increased the shearing stress surface greatly.It is radially stressed that the elasticity of standard is nullified shaft coupling nylon pin, and the radial section that its stress surface is the nylon pin amasss; The nylon pin of novel coupler is stressed vertically, and its stress surface is that the axial cross section of nylon pin is long-pending; The nylon pin of same model, its axial cross section is long-pending to be 3.2 times that radial section amasss, its anti-shearing force improves greatly.Transmit bigger moment of torsion if desired, under the prerequisite that does not change the shaft coupling profile, also can select the stronger rod pin of shear resistance for use, with the moment of torsion of further raising shaft coupling transmission.
Owing to increased the section of shear of shaft coupling nylon pin greatly, greatly reduced the accident that causes because of after nylon rod or the cut-out of other material.Can in the utility model shaft coupling, use at the cut nylon pin of scrapping of other units, all can put into shaft coupling so long as not cracked fully nylon pin and use, fully reach the purpose of twice laid.The reduction of accident rate has increased the effective operation rate of equipment, has improved output.The reduction of accident has reduced fittings cost, and the comprehensive utilization of refuse has reduced production cost.
Than high pulling torque, and all can use by instantaneous load plant equipment big, frequent starting in the needs transmission for this novel coupler.The utility model is simple in structure, can carry bigger shearing force, and the moment transmission is steady, guarantees long-time normal use of shaft coupling.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 looks cross-sectional view for master of the present utility model;
Fig. 2 is the side-looking structural representation of Fig. 1.
The specific embodiment
A kind of improved dead-beat drawing machine case butt coupling, as Fig. 1, shown in Figure 2, comprise driving wheel 3 that links to each other with motor shaft and the driven pulley 1 that links to each other with rotating shaft, the driving section of driving wheel 3 is sleeve shaped, the driving section of driven pulley 1 is cylindrical, cylindrical driving section engage sleeves is contained in the sleeve shaped driving section, semi-circular recesses is being set respectively on the axial periphery edge of driven pulley driving section and on the axial inner peripheral in the driving wheel driving section uniformly at intervals, semi-circular recesses constitutes cylinder shape groove in twos relatively, cooperate suit spring column pin 2 in each cylinder shape groove respectively, spring column pin 2 parallels with the axis of driven pulley 1.
Said spring column pin 2 is nylon rod or rod pin, and the number of spring column pin 2 is 8.
