Abstract
The utility model provides a safe and flexible shaft coupling having the buffering function and belongs to the technical field of shaft couplings. According to the technical scheme of the utility model, the shaft coupling comprises an outer gear ring, an inner fluted disc, a plurality of drum-type rubber bolts, an elastic half coupling and a safe half coupling. The elastic half coupling and the safe half coupling are respectively arranged on the end portion of a driving shaft and the end portion of a driven shaft. The plurality of drum-type rubber bolts are evenly embedded at the rim of a flange plate at the end portion of the elastic half coupling, and the axes of the rubber bolts are parallel to a transmission shaft. Each drum-type rubber bolt is inserted with a pin coaxial with the drum-type rubber bolt. The outer gear ring is slidably sleeved onto the end portion of the safe half coupling and is engaged with the inner fluted disc coaxially fixed on the safe half coupling. One side of the outer gear ring, positioned opposite to the elastic half coupling, is fixedly connected with the pins of the drum-type rubber bolts through a flange. According to the technical scheme of the utility model, due to the adoption of the safe and flexible shaft coupling, the mechanical vibration of a rolling-cut steel plate crosscut shear is effectively prevented from being directly transferred to a prime mover, and the relative displacement between the driving shaft and the driven shaft can also be compensated. Therefore, the buffering and damping capability of the shaft coupling is greatly improved and equipment is more stable and more reliable in operation.
Description
Technical field
The utility model relates to a kind of main transmission shafting coupling for slab rolling equipments such as roll-turning steel plate cross cut shears, belongs to the coupling technical field.
Background technique
The main transmission shafting coupling of roll-turning steel plate cross cut shears is the important transmission part of steel plate cross cut shears, and because roll-turning steel plate cross cut shears needs frequent starting, braking in the course of the work, so the load that this coupling bears differs greatly.at present, what the main transmission shafting coupling of roll-turning steel plate cross cut shears adopted is all gear coupling, this coupling be gap between inner external tooth and slippage compensate between driving shaft and driven shaft relative displacement (radially, axially, angle), when part is out of shape with relative slippage at stand under load, easily wear and tear, thereby make main, driven shaft produces additional relative displacement, and gear coupling does not have elastic hysteresis performance (loading curve and unloading curve are two characteristic curves), the bumper and absorbing shock ability is poor, can not bear larger temporary impact load and dynamic load.In addition, gear coupling does not have overload protection function, when the moment of torsion that transmits surpasses limit value, is easy to cause the damage of important parts.
The model utility content
The purpose of this utility model is the drawback for prior art, a kind of simple in structure, reliable operation is provided and has the safe flexible coupling of pooling feature.
Problem described in the utility model realizes with following technical proposals:
a kind of safe flexible coupling with pooling feature, formation comprises external toothing, interior fluted disc, a plurality of drum type rubber bolts and be contained in respectively driving shaft and the elasticity half-coupling of driven shaft end and safe half-coupling, a plurality of drum type rubber bolts evenly are embedded in the flange plate periphery of elasticity half-coupling end, their axis is parallel with transmission shaft, on each drum type rubber bolt, all be inserted with coaxial with it pin, described external toothing slides over the end of safe half-coupling and meshes with the interior fluted disc that coaxially is fixed on safe half-coupling, its side relative with the elasticity half-coupling is fixedly connected with the pin of drum type rubber bolt by flange.
Above-mentioned safe flexible coupling with pooling feature, be provided with copper sheathing between external toothing and safe half-coupling.
Above-mentioned safe flexible coupling with pooling feature, described interior fluted disc is connected with safe half-coupling by the safety pin of middle part with circular groove.
Between two half-couplings of the present utility model, by intermeshing interior fluted disc, external toothing and a plurality of drum type rubber, tie and connect, greatly improved the bumper and absorbing shock ability of coupling, this coupling not only can effectively avoid the mechanical vibration of roll-turning steel plate cross cut shears and impulsive load directly to pass to prime mover, can also compensate the driving shaft that causes due to a variety of causes and the relative displacement between driven shaft, make the equipment operation more steady, work more reliable.Safety pin fractures in the time of can surpassing limit value at the moment of torsion of coupling transmission automatically, prevents that important parts from damaging because moment of torsion is excessive.
The accompanying drawing explanation
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure, each label is: 1, elasticity half-coupling, 2, pin, 3, the drum type rubber bolt, 4, external toothing, 5, interior fluted disc, 6, safety pin, 7, safe half-coupling, 8, copper sheathing.
Embodiment
Referring to Fig. 1, the utility model mainly consists of elasticity half-coupling 1, pin 2, drum type rubber bolt 3, external toothing 4, interior fluted disc 5, safety pin 6, safe half-coupling 7, copper sheathing 8.Elasticity half-coupling 1 is fixed on driving shaft, and in the circular hole of its end flange dish, setting-in drum type rubber bolt 3, and drum type rubber bolt 3 is connected with the external toothing 4 of the approximate U-shaped of cross section by coaxially being inserted into its inner pin 2; One end of pin 2 adopts the mode of bolton to be fixed on a side of external toothing 4, and the other end passes drum type rubber bolt 3 and by plain washer and snap ring and drum type rubber bolt 3 fixing and lockings.Be fixed on safe half-coupling 7 on driven shaft by safety pin 6 and interior fluted disc 5 rigid joint in the circular hole on its male flange, when the moment of torsion that transmits surpassed limit value, safety pin 6 was cut off; For preventing that safety pin 6 plastic deformations from delaying to cut off, the material selection tensile strength of safety pin 6 is greater than 600Mpa, and hardness reaches the low alloy steel of HRC=30 ~ 36.Between the endoporus of external toothing 4 and safe half-coupling 7, with two copper sheathings 8, link, during assembling, external toothing 4 can be done the axial and circumferential slip along safe half-coupling 7, has guaranteed the correct engagement of interior fluted disc 5 and external toothing 4.
