Description

Technical Field

[0001] This invention relates to the field of mechanical transmission components, and in particular to a novel rod-end driven driven bearing device. Background Technology

[0002] Bearings are essential functional components in modern machinery. Their primary function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy and balanced operation. They are widely used in various machines and instruments. High load capacity, impact resistance, and a long reliable service life are their most basic requirements. Mechanical bearings are classified into two main categories based on the frictional nature between moving elements: rolling bearings and sliding bearings. In heavy machinery, bearings are often combined with other mechanical components to form suitable bearing devices that provide fixation, positioning, and protection. When this type of bearing device is installed at both ends of the rod, it can both fix and support the rod ends and ensure the rod operates smoothly and with low resistance. It is collectively referred to as rod end bearing device. It is installed in pairs at both ends of the rod and has the functions of main drive and driven by the rod. The structure also differs. The bearing device installed at one end of the rod and driven by external kinetic energy is the rod end drive bearing device. The bearing device installed at the other end of the rod and driven by the rotation of the rod is the rod end driven bearing device. The two work together to support and drive the rod to operate in a stable working state with a limited speed.

[0003] This application relates to a rod-end driven and driven bearing device, an innovative product developed based on existing rod-end driven and driven bearing devices. Existing rod-end driven and driven bearing devices mainly include a stator assembly, a rotating assembly, a lubricating bearing assembly, and a front-end power input drive component assembled and connected to the rotating assembly. The stator assembly is fixed in the middle of the main body, the rotating assembly is exposed on the periphery of the main body, and the lubricating bearing assembly is located between the stator assembly and the rotating assembly. In practice, it has been found that this type of driven and driven bearing device performs reasonably well in the initial operation phase, but its long-term operational stability becomes increasingly apparent with the passage of time. The ball bearings suffer from poor stability, short continuous reliable service life, and frequent shutdowns for maintenance due to uneven rod rotation or even jamming, disrupting normal equipment operation. During maintenance, it is often found that this is caused by foreign objects or contaminants solidifying in the lubricating oil grooves, preventing normal rotation. Furthermore, because the rotating components are directly exposed on the outermost layer of the bearing assembly, the high-speed airflow generated around them during high-speed rotation significantly disturbs the surrounding air, causing dust and noise pollution, and posing safety hazards to the surrounding work environment. Therefore, the ball bearings suffer from numerous shortcomings, including an unscientific and unreasonable structure, poor operational stability, high maintenance workload, high operating costs, and environmental pollution and safety hazards. From both economic and practical perspectives, they are unsatisfactory and have become a major problem plaguing the industry. Therefore, it is necessary to innovate the design by focusing on the scientific rationality of the structure to meet the reliable requirements of heavy-duty mechanized equipment for high-load, high-efficiency, low-cost, and continuous safe operation in complex environments. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing rod end driven bearing devices and provide a novel rod end driven bearing device with a relatively scientific and reasonable structure, stable and reliable operation, strong anti-pollution and anti-interference capabilities, which helps to reduce the workload of daily maintenance, improve operational stability and ensure normal service life, and can fully meet the requirements of efficient, low-cost and continuous safe operation of applicable equipment in complex environments.

The stator assembly comprises an intermediate stator shaft, a positioning disc, and an outermost external fixed housing for the bearing device. The rotating assembly is internally mounted and movably disposed within a cylindrical cavity between the intermediate stator shaft and the fixed housing of the stator assembly. The lubricating bearing assembly is disposed between the rotating assembly and the fixed housing. A buffer discharge assembly is further provided at the junction between the stator assembly and the rotating assembly.

[0006] The positioning disc body is in the shape of a stepped disc, consisting of an inner cylindrical ring fixedly sleeved on the outer periphery of the front end of the intermediate stator shaft and a flat outer disc fixed on the outer periphery of the front end of the inner cylindrical ring. On the inner end ring surface of the inner cylindrical ring, there is a ring limiting groove with several spring mounting holes for springs with pin compression springs as needed at its bottom. On the outer wall of the ring limiting groove, there is a retaining ring mounting groove A with a retaining retaining ring A as its inner wall. On the disc surface of the outer disc close to the inner cylindrical ring, there are several anti-rotation screw holes. The disc surface near the edge is set to be flattened with the upper and lower sides tapering inward as needed, and there are several bolt limiting assembly holes A with fastening bolts A mounted on them.

A number of bolt limiting mounting holes A corresponding to the bolt limiting mounting holes A are fixed on the top ring surface of the top ring.

[0008] The rotating assembly consists of a long cylindrical rotating sleeve that is movably fitted onto the main body of the intermediate stator shaft with a small gap. The inner ring surface of the front end of the cylindrical rotating sleeve is provided in a concave stepped shape, with a moving ring mounting surface and several anti-rotation pin mounting holes. A retaining ring mounting groove B with a limiting retaining ring B inside is fixed on the outer ring surface of the cylindrical rotating sleeve. A limiting retaining shoulder is fixed on the outer ring surface of the tail end of the cylindrical rotating sleeve. A retaining ring mounting groove C with a limiting retaining ring C inside and several retaining pin mounting holes with limiting retaining pins inside are fixed on the top ring surface of the cylindrical rotating sleeve.

[0009] The lubricated bearing assembly includes a lubricating oil ring groove formed by an inner ring groove fixed on the outer ring surface of the rotating sleeve and an outer ring groove fixed on the inner ring surface of the fixed housing; a ball bearing disposed in the lubricating oil ring groove; an oil baffle plate disposed on the front end face of the lubricating oil ring groove and held by a limiting protrusion ring on the main body, a limiting retaining ring B on the rotating sleeve, and the outer ring surface of the rotating sleeve; an inner end cap disposed on the rear end face of the lubricating oil ring groove; a skeleton oil seal disposed on the inner ring surface of the inner end cap; an outer end cap disposed on the outer ring surface of the inner end cap and the skeleton oil seal, having a bolt limiting assembly hole B near the edge and being assembled and limited with the fixed housing by a fastening bolt B; and a limiting retaining ring disposed close to the side of the inner ring surface of the outer end cap, limited by a limiting retaining ring, and sleeved on the outer periphery of the rotating sleeve near the rear end.

[0010] The aforementioned front-end power input component has the function of receiving the rotational kinetic energy of the rod body and driving the rotating component to rotate synchronously around the intermediate stator shaft. It consists of an outer rotating cylinder with an outer limiting protrusion ring and an inner concave ring surface that match the aforementioned limiting shoulder set, and a rod end connecting sleeve that is assembled and connected to the rod body. A pin extension hole that corresponds to the insertion of the limiting pin in the pin placement hole is fixed on the inner concave ring surface.

[0011] The buffer discharge assembly includes a buffer moving ring fixed to the moving ring mounting surface by an O-ring retainer, a buffer moving ring fixed by a retaining ring D, a retaining ring A for anti-slip positioning, a compression spring with a pin in the spring mounting hole for support positioning, a buffer stationary ring in the annular retaining groove, an anti-rotation pin fixed in the anti-rotation pin mounting hole with its top end flush with the inner ring surface of the buffer moving ring, and an external discharge groove formed by the gap between the positioning plate and the bottom end of the rotating sleeve and the lubrication bearing assembly.

[0012] In the assembled state, the positioning plate is fixedly sleeved on the outer periphery of the front end of the intermediate stator shaft, and is connected to the fixed housing by fastening bolt A to form a rigid integrated stator assembly. The tail end of the rotating sleeve is inserted and limited to the front power input component, forming a rotating assembly driven by the lubricated bearing assembly and capable of rotating synchronously at high speed with the rod body. It is also fixedly connected to the external support frame by the anti-rotation screw hole on the positioning plate, forming a novel, stable, safe and reliable, environmentally friendly and practical rod end driven driven bearing device with a fixed outer shell, reliable fixing and support of the rod end and the rod body, driven and balanced high-speed operation, and can be detached as needed.

[0013] In addition, at least two support bars are provided.

[0014] Based on the above concept, the present invention provides a novel rod-end driven bearing device. Through comprehensive and innovative structural design of the stator assembly, rotating assembly, lubrication bearing assembly, and front-end power input component, the rotating assembly is built-in, and the bearing device's outer shell is a fixed structure formed by the fixed shell within the stator assembly. Utilizing aerodynamic principles, a buffer-resistant drainage component with immediate outward airflow dispersion function is scientifically added at the junction of the stator and rotating assemblies. This effectively overcomes the safety hazards, noise, and environmental pollution associated with placing the rotating assembly on the outer layer of the bearing device's main body in existing technologies. It also ensures the rotating assembly operates normally in a built-in, interference-free environment, and eliminates the traditional pollution effects on the lubricating oil groove, ensuring normal working life. The technical solution of this invention is simple and scientifically sound, stable and reliable in operation, has a long service life, requires minimal maintenance, and is safe and environmentally friendly. While ensuring the normal operation of the rod, it also provides a fundamental guarantee for the efficient, highly reliable, low-cost, safe, and pollution-free continuous operation of mechanical equipment using the bearing device of this invention. It effectively solves a major problem in existing technologies and represents a significant innovation in this field, possessing strong practicality and promising market application prospects.
