Abstract
The utility model discloses a quick-assembly elastic pin gear coupling, which belongs to the technical field of mechanical engineering and comprises a pair of coupling halves capable of holding a pin and a jacket matching with the pin on the coupling halves. The two coupling halves are connected with the jacket through the pin to transmit torque; an expansion coupling sleeve is arranged on inner rings of the coupling halves; and an input shaft and an output shaft are connected with the coupling halves through the expansion coupling sleeve. The expansion coupling sleeve is combined with a common elastic pin gear coupling so that production and installation of a principal machine are simple, the expansion device can be installed without being heated or cooled, or can be installed by means of screwing up bolts through a pressurizing device according to the required torque, and can be adjusted conveniently, thereby greatly improving assembly efficiency and saving time for device replacement. As the adopted expansion coupling sleeve relying on friction transmission has no weakening effect to coupled parts due to keys and grooves, and has no relative movement, abrasion is avoided during the operation, and accordingly the quick-assembly elastic pin gear coupling is long in service life and high in intensity.
Description
Technical field
The utility model relates to a kind of coupling, and the specifically a kind of transmission system that can assemble fast belongs to mechanical engineering technical field with quick mounting type spring column pin gear coupling.
Technical background
At present, the assembling form between well-known coupling and the working shaft divides two kinds of cold charge and hot chargings.Cold setting can be divided into two kinds again, and a kind of to be the mode of knocking by hydraulic pressure or weight pack the axle of prime mover or driven machine in the axis hole of coupling into, and its shortcoming is the assembling difficulty, fragile equipment and coupling, and dismounting inconvenience.Another kind is meant input, the output shaft that cools off prime mover and driven machine with liquid nitrogen fast, utilizes the principle of expanding with heat and contract with cold, and with the size of importing, output shaft is cooled to pack into easily, thereby guarantees carrying out smoothly of assembling.Its shortcoming is that assembly condition is harsh, and is higher to operator's technical requirements, and the dismounting difficulty.Hot charging is joined the mode that is meant by heating coupling axis hole, utilizes the principle of expanding with heat and contract with cold, and guarantees the method that input, output shaft are packed into smoothly.Its shortcoming is requirement height, the dismounting inconvenience to operator, and can not use the method in explosion-proof, inflammable occasion.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of assembling, convenient disassembly, less demanding to operator, be subjected to ambient environmental conditions to influence little quick mounting type spring column pin gear coupling.
In order to solve the problems of the technologies described above quick mounting type spring column pin gear coupling of the present utility model, include the overcoat that a pair of half-coupling of settling pin and cooperate with pin on the half-coupling, two half-couplings are connected with overcoat by pin, with transmitting torque; The inner ring of described half-coupling is provided with expansion coupling sleeve, and input shaft and output shaft connect with half-coupling by expansion coupling sleeve.The two ends of described overcoat are provided with the baffle plate that is connected on the half-coupling.
After adopting such structure, because expansion coupling sleeve and ordinary elasticity pin gear coupling are combined, make the main frame part make and install simple, unlike interference fit, require high-precision manufacturing tolerances by the axle of swelling assembling and the processing in hole, swelling device need not heat when installing, cooling or pressurized equipment, only bolt moment on request need be tightened and get final product, and it is easy to adjust, can improve efficiency of assembling greatly and save the more time of exchange device, particularly can't hot charging join or hot charging is joined special occasions such as inconvenience and provided very big facility for the smooth assembling of coupling in the down-hole.Because the expansion coupling sleeve that uses relies on friction driving not have keyway to weaken to being coupled part, there is not therefore long service life of the wearing and tearing of can not producing in the relative movement work, the intensity height simultaneously yet.
Description of drawings
Fig. 1 is the erection drawing of the utility model quick mounting type spring column pin gear coupling.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model quick mounting type spring column pin gear coupling is described in further detail.
As shown in the figure, use in the mounting assembly of the utility model quick mounting type spring column pin gear coupling, comprise input shaft, output shaft, pin, half-coupling; Input shaft 1 connects with a half-coupling 2 by expansion coupling sleeve 7, and output shaft 9 connects with another half-coupling 2 by expansion coupling sleeve 7; Two half-couplings 2 are connected with transmitting torque with overcoat 4 by pin 5.During assembling, elder generation packs input shaft 1 in half-coupling 2 axis holes, the expansion coupling sleeve 7 of packing into, press standard-required, the cinch bolt 6 of expansion coupling sleeve 7 is applied the moment of torsion of regulation, in half-coupling 2 axis holes of again output shaft 9 being packed into, the expansion coupling sleeve 7 of packing into, press standard-required, the cinch bolt 6 of expansion coupling sleeve 7 is applied the moment of torsion of regulation.Be respectively charged into pin 5 overcoat 4 of packing into then, move initiatively machine or driven machine, adjust the two axial ends spacing, baffle plate 3 is installed on the overcoat two ends reliably with the end cap screw to given size.During dismounting,, unclamp cinch bolt 6 as long as remove prime mover or driven machine, slowly tighten demounting bolt to certain position, save the more time of exchange device thereby can easily change or keep in repair, particularly at special occasions such as down-holes, for the smooth assembling of coupling provides sound assurance.
