Description

Technical Field

[0001] The utility model relates to the technical field of chains, in particular to an energy-saving chain used in a glove production line. Technical Background

[0002] Chains can be used for conveying, transmission, etc. They are usually composed of axles, bushings, pulleys and inner and outer chain plates. Generally, the axle is in clearance fit with the bushing outside the axle, the pulley is sleeved on the bushing, the outer chain plate is arranged on the axle, and the inner chain plate is arranged on the bushing. When the chain is transmitted on the production line, relative friction between the parts at each socket joint will cause loss and heat, and after long-term use, jamming and deviation will occur, resulting in unsmooth movement of the mold, reducing the service life of the chain and also being neither energy-saving nor environment-friendly, affecting the production process. Content of the Utility Model

[0003] The utility model aims to overcome the problems that the existing chains are prone to short service life, high energy consumption, easy jamming and easy deviation, and provides an energy-saving chain. The beneficial effects of the utility model are that the rotating parts are fully lubricated, E-type circlips are axially fixed at both ends of the axle to prevent deviation between the outer chain plate, inner chain plate, pulley, bushing and axle, which affects transmission. And the connecting shaft between the glove mold and the chain on the traditional glove conveying production line is set to be hollow, the inner chain plate is designed with a hollow structure, and the setting of the wire drawing groove and the hollow axle reduces the overall weight of the conveying device, further reducing energy consumption.

[0004] To achieve the above object, the utility model provides an energy-saving chain, including an outer chain plate, an inner chain plate, a pulley, an axle, and a bushing. The pulley is rotatably arranged on the bushing, the bushing is rotatably arranged on the axle, a first oil storage space is arranged between the pulley and the bushing, an oil outlet hole communicating with the first oil storage space is arranged on the bushing, a second oil storage space is arranged between the bushing and the axle, an oil injection hole communicating with the second oil storage space is arranged on the axle, an oil injection area communicating with the oil injection hole is opened inside the axle, and the port of the oil injection area is arranged on the end face of the axle. When injecting lubricating oil and other liquids into the oil injection area inside the axle through the end face of the axle, the liquid flows to the second oil storage space through the oil injection hole, and then flows to the first oil storage space through the oil outlet hole. The lubricating oil and other liquids will be distributed between the axle and the bushing and between the bushing and the pulley, so that each socket joint is fully lubricated during transmission, reducing friction. At the same time, the oil injection area inside the axle is hollow, reducing the overall weight of the conveying device, saving energy and being environment-friendly.

[0005] Further, a ring-shaped first oil storage groove and an internal wire groove are provided on the inner wall of the pulley. A first oil storage space is formed between the first oil storage groove and the outer wall of the bushing. The internal wire groove is spirally distributed on the inner wall of the pulley. A ring-shaped second oil storage groove and a wire groove are provided on the inner wall of the bushing. A second oil storage space is formed between the second oil storage groove and the outer wall of the shaft pin. The wire groove is spirally distributed on the inner wall of the bushing. By providing spiral wire grooves and internal wire grooves in the first oil storage space and the second oil storage space respectively, during the transmission process, when the pulley, the bushing, and the shaft pin rotate, liquids such as lubricating oil can flow along the wire grooves and the internal wire grooves and be evenly distributed in the first oil storage space and the second oil storage space. The settings of the first oil storage groove, the second oil storage groove, the wire groove, and the internal wire groove also create spaces between the shaft pin and the bushing, and between the bushing and the pulley, reducing the weight of the overall transmission device and lowering energy consumption.

[0006] Further, the internal wire groove is recessed towards the inner wall, and the wire groove protrudes outwards towards the inner wall. The outwardly protruding wire groove allows the liquid to flow more fully from the second oil storage space to the first oil storage space for sufficient lubrication. The inwardly recessed internal wire groove results in less friction and smoother rotation when the amount of oil in the second oil storage space is relatively small.

[0007] Further, a connecting shaft is fixedly provided perpendicular to the outer link plate at the central part of the outer link plate towards the outside of the energy-saving chain. The inside of the connecting shaft is hollow. The hollow connecting shaft can significantly reduce the weight of the overall transmission device, save transmission energy consumption, and achieve the effect of energy conservation and environmental protection.

[0008] Further, hollow holes are provided on the inner link plate. The provided hollow holes can significantly reduce the weight of the inner link plate, thereby greatly reducing the weight of the entire transmission device and saving transmission energy consumption.

[0009] Further, on the side of the outer link plate away from the pulley, an E-type circlip is used for axial fixation with the shaft pin. No axial offset occurs between the E-type circlip and the shaft pin. Therefore, the outer link plate, the inner link plate, the pulley, and the bushing are axially restricted by the E-type circlip, and no offset is likely to occur during the transmission process.

[0010] The utility model provides an energy-saving chain that can be fully lubricated and has a reduced weight. An oil injection area is provided inside the pin of the chain. After injecting a liquid such as lubricating oil into the oil injection area on the end face of the pin, the liquid flows through the oil injection hole to the second oil storage space between the bushing and the pin, and then flows through the oil outlet hole on the bushing to the first oil storage space. During the transmission process of the energy-saving chain, rotation occurs between the bushing and the pin, and between the bushing and the pulley. At this time, the spiral wire grooves on the inner wall of the bushing make the liquid evenly distributed between the bushing and the pin, enabling the bushing and the pin to be fully lubricated by the liquid such as lubricating oil. The spiral internal wire grooves on the inner wall of the pulley make the liquid evenly distributed between the pulley and the bushing, thereby reducing friction and loss. Moreover, the oil injection area inside the pin is hollow, and the settings of the first oil storage groove, the second oil storage groove, the wire grooves, and the internal wire grooves also create space between the rotating devices of the transmission device, reducing the weight of the overall transmission device, saving energy, and protecting the environment.

[0011] The utility model also provides an energy-saving chain. The wire grooves on the inner wall of the bushing protrude outward, and the internal wire grooves on the inner wall of the pulley are recessed inward. The outward-protruding wire grooves enable the liquid to flow more fully from the second oil storage space to the first oil storage space, achieving full lubrication.

[0012] The utility model also provides an energy-saving chain. The connecting shaft is arranged in a hollow structure, reducing the weight of the overall transmission chain, reducing loss, saving energy, and protecting the environment.

[0013] The utility model also provides an energy-saving chain. Hollow holes are provided on the inner link plate. The provided hollow holes can significantly reduce the weight of the inner link plate, thereby significantly reducing the weight of the entire transmission device and saving transmission energy consumption.

[0014] The utility model also provides an energy-saving chain. On the side of the outer link plate away from the pulley, an E-type snap ring is used for axial fixation with the pin. No axial offset occurs between the E-type snap ring and the pin. Therefore, the outer link plate, the inner link plate, the pulley, and the bushing are all axially restricted by the E-type snap ring, and it is not easy to generate offset during the transmission process.
