A large disc gear rotating support device

Abstract

This utility model relates to a large disc gear rotation support device, specifically within the field of circular knitting machines. It includes a large disc, a large disc gear rotatably mounted on the upper side of the large disc, and a transmission component for driving the rotation of the large disc gear. A groove is created between the large disc and the large disc gear to accommodate a steel wire raceway bearing, enabling the large disc gear to achieve high speed and energy efficiency during rotation. Friction is significantly reduced during operation, meeting the demands of high-speed operation. Simultaneously, multiple side wear-resistant plates are adjustable and installed on the side wall of the large disc. These plates can be rotated outwards around a positioning pin using a locking screw, flexibly adapting to contact the inner wall of the large disc gear for positioning and support. Even when a portion of the wear-resistant layer of the wear-resistant plate is worn away, the remaining wear-resistant layer can still contact the large disc gear for positioning and support by pushing the locking screw, greatly improving its flexibility, stability, and durability.

Description

Technical Field

[0001] This utility model relates to a large disc gear rotating support device, and pertains to the field of circular knitting machine technology. Background Technology

[0002] During operation, the circular knitting machine operates with a fixed large disc and a rotating large disc gear. The sides and bottom of the large disc gear constantly rub against the inner wall and bottom of the large disc groove. The large disc is mostly made of gray cast iron, while the large disc gear is made of ductile iron. The high coefficient of friction between these castings causes two serious problems: first, it generates a large amount of heat, leading to wear and deformation of the workpiece; second, the high frictional resistance causes overloading, increasing the machine's energy consumption. Therefore, our company proposes an improved rotating support device for the large disc gear. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a large disc gear rotating support device to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a large disc gear rotating support device, including a large disc, a large disc gear rotatably disposed on the upper side of the large disc, and a transmission component for driving the rotation of the large disc gear. A steel wire raceway bearing is installed between the large disc and the large disc gear. Multiple wear-resistant plates are installed on the upper annular sidewall of the large disc, and the wear-resistant plates abut against the gear of the large disc through the outer side of the wear-resistant plates.

[0005] A further improvement is that grooves are provided on both the positioning surface on the upper side of the large disc and the positioning bottom surface of the large disc gear for installing the steel wire raceway bearing, allowing the large disc gear to rotate in a ring on the large disc.

[0006] A further improvement is that a positioning pin is vertically inserted through one side of the wear-resistant plate, and the plate is rotatably mounted on the upper side of the large plate through the positioning pin.

[0007] A further improvement is that the large disc ring array is equipped with multiple anti-slip screws, and the anti-slip screws penetrate the side wall of the large disc laterally and abut against the wear-resistant plate on the side away from the positioning pin. The wear-resistant plate on this side is adjusted and pushed against the inner side wall of the large disc gear.

[0008] A further improvement is that a wear-resistant layer is provided on the outer side of the side wear-resistant plate, and the wear-resistant layer contacts the inner side wall of the large disc gear.

[0009] A further improvement is that the wear-resistant layer has annular grooves for oil flow when the large disc gear rotates.

[0010] A further improvement is that the wear-resistant layer is a wear-resistant leather, and the wear-resistant plate and the wear-resistant layer are bonded together with high-temperature resistant and oil-resistant adhesive.

[0011] Compared with the prior art, the present invention has the following advantages: This invention utilizes grooves created between the large disc and the large disc gear to install steel wire racetrack bearings, enabling the large disc gear to achieve high speed and energy efficiency during rotation. Friction is significantly reduced during operation, meeting the demands of high-speed operation. Simultaneously, multiple side wear-resistant plates are adjustable and installed on the side wall of the large disc. These plates can be rotated outwards around a locating pin using a locking screw, flexibly adapting to contact the inner wall of the large disc gear for positioning and support. Even when a portion of the wear-resistant layer on the wear-resistant plate is worn away, the remaining wear-resistant layer can still contact the large disc gear for positioning and support by pushing the locking screw forward, greatly improving its flexibility, stability, and durability.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Please see Figures 1-4This utility model provides a technical solution for a large disc gear rotating support device: it includes a large disc 1, a large disc gear 3 rotatably mounted on the upper side of the large disc 1, and a transmission component 2 for driving the rotation of the large disc gear 3. The transmission component 2 mainly consists of a transmission shaft and a drive gear. The transmission shaft drives the large disc gear 3 to rotate through the meshing of the drive gear. A steel wire raceway bearing 4 is installed between the large disc 1 and the large disc gear 3. Specifically, the positioning surface on the upper side of the large disc 1 and the positioning bottom surface of the large disc gear 3 are designed with corresponding grooves for installing the steel wire raceway bearing 4. This allows the large disc gear 3 to rotate in a ring on the large disc 1, improving the rotation speed and energy saving effect, and significantly reducing friction during operation to meet the requirements of high-speed operation.

[0015] Furthermore, the upper annular sidewall of the large disc 1 has multiple grooves arranged in annular array, and each groove is fitted with a side wear-resistant plate 5. The side wear-resistant plate 5 abuts against the large disc gear 3 through its outer side, which not only achieves the effect of small parts with large positioning, but also reduces the wear of the sidewall when the large disc 1 and the large disc gear 3 rotate, making the rotation of the large disc gear 3 more stable.

[0016] Furthermore, a positioning pin 6 is vertically inserted through one side of the wear-resistant plate 5, and is rotatably mounted on the upper side of the large disc 1 via the positioning pin 6, allowing the wear-resistant plate 5 to rotate along the positioning pin 6. This improves the adjustability of the outward protrusion distance of the wear-resistant plate 5 to accommodate the inner wall thickness of different models of large disc gears 3. Multiple fixing screws 7 are installed in a circular array on the large disc 1, and each fixing screw 7 passes horizontally through the side wall of the large disc 1 and abuts against the side of the wear-resistant plate 5 away from the positioning pin 6. By turning the fixing screw 7, the degree of pushing and protruding of the wear-resistant plate 5 on that side can be adjusted, flexibly pushing it against the inner wall of the large disc gear 3 to provide stable positioning support and improve applicability and convenience.

[0017] Furthermore, a wear-resistant layer 51 is provided on the outer side of the side wear-resistant plate 5, and it contacts the inner wall of the large disc gear 3 through the wear-resistant layer 51. The wear-resistant layer 51 is a wear-resistant skin. The wear-resistant plate 5 and the wear-resistant skin are bonded together with high-temperature resistant and oil-resistant adhesive. Using the wear-resistant skin to contact the inner wall of the large disc gear 3 can prevent the wear of the large disc 1. Moreover, when a part of the wear-resistant skin contact surface of the wear-resistant plate 5 is worn away, the remaining part of the wear-resistant skin can still continue to contact the large disc gear 3 for positioning and support by pushing in the fixing screw 7, which greatly improves its flexibility, stability and durability.

[0018] In addition, annular grooves 52 are provided on the wear-resistant leather to allow oil to flow when the large disc gear 3 rotates. In this way, the oil will be rolled up to form an echo wall during the operation of the large disc gear 3. The annular grooves 52 facilitate oil drainage from the gear and reduce noise generation.

[0019] It should be noted that the present invention provides a large disc gear rotating support device, which mainly improves the above-mentioned structure. The functions, components and structures not mentioned can be implemented by using existing components and structures that can achieve the corresponding functions.
