Abstract
The utility model discloses a flange coupling connected with a universal shaft, which aims at solving the problem that the alignment is difficult when the conventional coupling is replaced. The flange coupling comprises a left half coupling and a right half coupling, wherein, connecting bolt holes are correspondingly formed on flanges of both the left half coupling and the right half coupling; keys and key slots are also correspondingly formed on the flanges of the left half coupling and the right half coupling; the keys and the key slots are matched with each other so as to transfer torque; the keys and the key slots are formed along the diameters of the flanges of the couplings symmetrically, and each pair of the keys and the key slots are formed on the left side and the right side respectively; and the keys and the flanges of the couplings are combined into a whole. The improved flange coupling is very convenient to install, the centering of an axial line and the installation of a bolt are very simple, and the work efficiency is improved; the improved flange coupling does not need a positioning hole, the requirement on the positions of the holes, reference circles and deviation of pore diameters is lower, and the interchangeability of the couplings in the same type can be improved greatly at the same time; in addition, the keys and the flanges are combined into a whole, so that the mechanical strength of the keys can be high, larger torque can be transferred, and daily inspection and maintenance is not needed.
Description
Technical field
The utility model relates to a kind of coupling, relates in particular to a kind of flange coupling that connects with cardan shaft.
Background technique
130 in the existing travelling crane of the cold rolling head factory of Wuhan Iron and Steel Plant, the transmission part of all travelling crane all adopts the cardan shaft transmission, and an end of cardan shaft connects with the output shaft of speed reducer, and the other end connects with wheel axle, and two interfaces all adopt flange coupling to connect.When wheel needed to change for a certain reason, an end of the flange coupling that connects with wheel axle was also changed thereupon.Caused the problem of two aspects like this: one side is owing to the flange coupling employing is the articulation hole Bolt Connection, and 8 holes and four locating studs are arranged, therefore require high to the positioning hole of flange coupling and the position and the aperture of connecting hole, two parts that often occur flange coupling in the process of installing can't connect or the part aperture can't accurately be aimed at, so can't normally connect; On the other hand because the other end and the cardan shaft of flange coupling is one, cardan shaft weighs 0.5 ton and can arbitrarily swing, thus difficult to boring ratio when mounted, having increased the repair time greatly, operating efficiency is lower.
The model utility content
The purpose of this utility model is to overcome the prior art defective, and a kind of flange coupling that connects with cardan shaft is provided, and connects when making things convenient for coupling to change.
The technical solution of the utility model is achieved in that a kind of flange coupling that connects with cardan shaft, form by left half-coupling and right half-coupling, correspondence has the connecting bolt hole on left side half-coupling and the right half-coupling flange, it is, also correspondence has key and keyway on left half-coupling and right half-coupling flange, key and keyway cooperatively interact, in order to transmitting torque.
Further, described key and keyway arrange along the coupling flange diameter symmetry, about each is a pair of.
Further, described key and coupling flange are an integral body.
Flange coupling after the improvement installs very convenient, axis in and the installation of bolt all very simple and direct, improved operating efficiency, and the flange coupling after improving does not need positioning hole, requirement to position, standard pitch circle and the aperture deviation in hole is lower, has improved the interchangeability of this type coupling simultaneously greatly.Key and flange are integral type, make the mechanical strength height of key, can transmit than high pulling torque and need not current check and maintenance.
Description of drawings
Accompanying drawing 1 is the utility model connection diagram.
Accompanying drawing 2 is left half-coupling schematic representation.
Accompanying drawing 3 is right half-coupling schematic representation.
Among the figure, the 1-cardan shaft; 2-left side half-coupling; The right half-coupling of 3-; The 4-bolt hole; The 5-wheel axle;
The 6-key; The 7-keyway
Embodiment
Be further described below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, shown in Figure 3, left side half-coupling 2 directly connects with cardan shaft 1, right half-coupling 3 adopts key to be connected with the axle head of wheel axle 5, on the flange of left half-coupling, process two rectangular keys of arranging along diameter symmetry 6 with milling machine, on the flange of right half-coupling, process the keyway 7 that matches with left half-coupling key, moment of torsion between cardan shaft 1 and the wheel axle 5 is transmitted by key 6 and keyway 7, two half-couplings are connected by bolt hole 4 by six plain bolts, no longer need the locating stud location.The torque of transmitting when the concrete size at each position can be passed through to use is determined.
Claims (3)
1. flange coupling that connects with cardan shaft, form by left half-coupling and right half-coupling, correspondence has the connecting bolt hole on left side half-coupling and the right half-coupling flange, it is characterized in that: also correspondence has key and keyway on left half-coupling and right half-coupling flange, key and keyway cooperatively interact, in order to transmitting torque.
2. a kind of flange coupling that connects with cardan shaft according to claim 1 is characterized in that: described key and keyway arrange along the coupling flange diameter symmetry, about each is a pair of.
