Abstract
The utility model provides a double-pin-shaft structure on a transmission mechanism of a roller chain pipe coiling machine. A machine body of a pipe coiling machine is fixedly connected with a main shaft of the pipe coiling machine. The main shaft of the pipe coiling machine is provided with a main shaft sleeve and a belt wheel. The belt wheel is connected with a motor belt disc through a belt. The main shaft sleeve and the belt wheel are provided with a main shaft sleeve pin shaft groove I and a belt wheel pin shaft groove I, which are fixedly connected together through a pin shaft I in a manner of plugging. The main shaft sleeve and the belt wheel are provided with a corresponding main shaft sleeve pin shaft groove II and a corresponding belt wheel pin shaft groove II. A pin shaft II is plugged into the main shaft sleeve pin shaft groove II and the belt wheel pin shaft groove II to further fix the main shaft sleeve and the belt wheel. The main shaft sleeve pin shaft groove I and the belt wheel pin shaft groove I, and the main shaft sleeve pin shaft groove II and the belt wheel pin shaft groove II are arranged at the two end parts of the same main shaft diameter line of a main shaft of the pipe coiling machine. According to the double-pin-shaft structure on a transmission mechanism, unbalanced operation, and shaking and swinging do not happen after the belt wheel is used for a long period, so that the pipe coiling machine can continuously and normally work and the pipe coiling quality of the pipe coiling machine can be ensured.
Description
Technical field
The utility model relates to the pin shaft structure on a kind of driving mechanism, particularly the double pin axle structure on a kind of roller chain rolling machine driving mechanism.
Background technique
At present, in produceing enterprises of chain, be with special-purpose roller chain rolling machine the band steel band to be rolled into axle sleeve when producing the axle sleeve in the roller chain.My company uses many axle sleeves that the band steel band of all size rolled into all size by the roller chain rolling machine of Zhejiang Province's Zhuji Chain Equipment General Factory production always for many years.In this roller chain rolling machine, only be connected by a bearing pin between the main shaft sleeve on the main shaft and the belt pulley on the main shaft.Because only being connected by a bearing pin between main shaft sleeve and the belt pulley, making belt pulley just generation imbalance after long-term the use turn round and rock swing, thereby affect the continuous normal operation of rolling machine and the pipe crimping quality of rolling machine.
Summary of the invention
The purpose of this utility model provides the double pin axle structure on a kind of roller chain rolling machine driving mechanism.This double pin axle structure makes belt pulley can not produce uneven running after long-term use and rocks swing, thereby can guarantee pipe crimping function continuously normal operation and the pipe crimping quality that can guarantee rolling machine.
The technical solution of the utility model is: the double pin axle structure on a kind of roller chain rolling machine driving mechanism.The rolling machine body is connected with the rolling machine main shaft.On the rolling machine main shaft, be connected with main shaft sleeve by keyway and key.Belt pulley also is equipped with in the main shaft sleeve outside on the rolling machine main shaft.Belt pulley is connected with the electric motor belt dish by belt.All have corresponding main shaft sleeve pin groove I and belt pulley pin groove I on main shaft sleeve and the belt pulley.Bearing pin I latch is fixed together in main shaft sleeve pin groove I and belt pulley pin groove I and with main shaft sleeve and belt pulley.Be characterized in: also have corresponding main shaft sleeve pin groove II and belt pulley pin groove II on main shaft sleeve and the belt pulley.Bearing pin II latch further is fixed together main shaft sleeve and belt pulley in main shaft sleeve pin groove II and belt pulley pin groove II.Main shaft sleeve pin groove II and belt pulley pin groove II and main shaft sleeve pin groove I and belt pulley pin groove I are opened the place, position, two end part at the same main shaft diameter line of rolling machine main shaft.Bearing pin I and bearing pin II consist of the double pin axle structure on the roller chain rolling machine driving mechanism.
The utility model carries out double pin axle to main shaft sleeve and belt pulley and is fixedly connected with by increasing a bearing pin II, solve former 1 bearing pin I and main shaft sleeve is fixedly connected with belt pulley has made the stressed unbalanced defective of belt pulley, no longer rocked swing when belt pulley is rotated.
The double pin axle structure that provides on a kind of roller chain rolling machine driving mechanism is provided.This double pin axle structure makes belt pulley can not produce uneven running after long-term use and rocks swing, thereby can guarantee pipe crimping function continuously normal operation and the pipe crimping quality that can guarantee rolling machine.
