Abstract
Description
Technical Field
[0001] The utility model relates to a self-compensating sandwich nylon taper pin coupling structure, belonging to the technical field of roller transmission equipment in the metallurgical industry. Background Art
[0002] In the process of producing H-beams, the rolling mill needs to use rollers to transport the profiles. The rotation of the rollers is achieved by the motor driving the reducer, and the reducer drives the rollers through the taper pin coupling. During use, the taper pin and the coupling often wear each other. When the taper pin wears to a certain extent, it cannot withstand the corresponding torque, causing the taper pin to break, causing the coupling to lose its function, causing the roller to stop running. After the roller stops rotating, production will be forced to stop, which seriously affects production efficiency. At the same time, the taper pin and the taper pin hole in the coupling rub against each other, causing the taper pin hole to wear, deform and damage. The coupling needs to be replaced regularly, increasing the equipment maintenance cost. Utility Model Content

DETAILED DESCRIPTION
[0015] The present invention will be further described below through examples in conjunction with the accompanying drawings.
[0016] A self-compensating sandwich nylon tapered pin coupling structure comprises a roller side coupling 6, a reducer side coupling 7, a sandwich nylon tapered pin 8, a tapered pin baffle 9 and a frustum spring 13. The roller side coupling 6 and the reducer side coupling 7 are respectively evenly provided with a plurality of tapered holes 1 and tapered holes 2 along the circumferential direction. The tapered holes 1 and 2 are connected to form tapered pin holes. The maximum aperture of the tapered hole 1 is equal to the minimum aperture of the tapered hole 2. The tapered pin hole is provided with a sandwich nylon tapered pin 8 and a frustum spring 13. The frustum spring 13 is arranged close to the reducer side coupling 7. The roller side coupling 6 and the reducer side coupling 7 are both provided with a tapered pin baffle 9 on their outer sides. The tapered pin coupling 3 is assembled together. The sandwich nylon tapered pin 8 comprises a sandwich nylon tapered pin shell 11 and a steel tapered pin 12. The sandwich nylon tapered pin shell 11 is provided with a through hole. The steel tapered pin 12 is arranged in the through hole.
[0017] The roller side coupling 6 and the reducer side coupling 7 are respectively fastened to the cone pin baffle 9 by baffle bolts 10.
[0018] The truncated cone spring 13 comprises a truncated cone and a spring, one end of the spring is connected to the sandwich nylon cone pin 8, and the other end is connected to the truncated cone.
[0019] The frustum is a cylindrical structure, the outer diameter of the frustum is slightly smaller than the maximum aperture of the second conical hole, and the frustum is clamped in the second conical hole.
[0020] The roller table side coupling 6 and the reducer side coupling 7 of the tapered pin coupling 3 are connected to the roller table 5 and the reducer 2 respectively. The roller table 5 is provided with a bearing seat 4, and the reducer 2 is connected to the motor 1.
[0021] The through hole is a Φ6 / Φ12 platform-shaped through hole (i.e. a tapered through hole with a minimum hole diameter of 6 mm and a maximum hole diameter of 12 mm), and the steel cone pin 12 is a Φ6 / Φ12 45# steel cone pin.
[0022] In this embodiment, a Φ6 / Φ12 platform-shaped through hole is processed in the center of the sandwich nylon cone pin shell 11 of the sandwich nylon cone pin 8, and a Φ6 / Φ12 45# steel cone pin is embedded in the sandwich nylon cone pin shell 11. The embedded sandwich nylon cone pin shell 11 and the steel cone pin 12 are tightly matched to form a sandwich nylon cone pin 8; 8 conical holes 1 and 2 are processed in the circumferential direction on the roller side coupling 6 and the reducer side coupling 7 respectively to form 8 cone pin holes; 8 groups of sandwich nylon cone pins 8 are inserted from the ends of the cone pin holes of the reducer side coupling 7 until the roller is In the tapered pin hole of the coupling 6 on the roller side; after the sandwich nylon tapered pin 8 is installed, install the frustum spring 13 in the tapered pin hole of the reducer side coupling, install the tapered pin baffle 9, and tighten it with the baffle bolt 10. At the same time, tighten the tapered pin baffle 9 on the roller side coupling 6 with the baffle bolt 10 to prevent dust from entering the tapered pin hole of the tapered pin coupling 3. After the tapered pin coupling 3 is assembled, it is installed between the roller 5 and the reducer 2. During production, the motor 1 drives the reducer 2 to rotate, and the reducer 2 drives the roller 5 to rotate through the tapered pin coupling 3 to transport the profile.
[0023] The sandwich nylon taper pin 8 of the utility model adopts a structure in which a steel taper pin 12 is embedded inside a sandwich nylon taper pin shell 11, and the two are tightly matched after being embedded; since the nylon material of the outer layer of the sandwich nylon taper pin 8 is softer than the material of the taper pin coupling, the taper pin coupling will not be worn. At the same time, adding a 45# steel taper pin inside the sandwich nylon taper pin increases the strength of the sandwich nylon taper pin. In order to reduce the mutual friction between the sandwich nylon taper pin and the taper pin hole of the taper pin coupling, a frustum spring 13 is added to the large-size end of the sandwich nylon taper pin, and the taper pin baffles 9 and baffle bolts 10 on both sides of the taper pin coupling are used to fix it, thereby increasing the force on the sandwich nylon taper pin 8. Even if the surface of the sandwich nylon taper pin is worn, the wear amount will be eliminated under the action of the spring, thereby achieving tight fit between the sandwich nylon taper pin and the taper pin hole of the coupling, avoiding relative movement, reducing friction, and improving the service life of the sandwich nylon taper pin and the taper pin coupling.
[0024] Under the premise of ensuring the function of the tapered pin coupling, the utility model reduces the friction between the tapered pin hole of the tapered pin coupling and the sandwich nylon tapered pin by using nylon material and a self-compensation structure, improves the cooperation with each other, improves the production efficiency and reduces the equipment maintenance cost.
