Description

Technical Field

[0001] This utility model relates to the field of steel ball turntable technology, specifically to a steel ball turntable support assembly. Background Technology

[0002] A steel ball turntable support assembly is a mechanical component used to support and realize relative rotational motion. It typically consists of an inner ring, an outer ring, steel balls, and spacers. It achieves relative rotational motion between the inner and outer rings by the rolling of steel balls between the inner and outer ring raceways. When the outer ring is subjected to an external force, the steel balls roll within the raceways, thereby driving the other ring to rotate.

[0003] When steel balls roll, they need to be evenly separated by spacers to prevent them from colliding and rubbing against each other. The structure of a typical spacer is relatively simple. When rotating at high speed, the steel balls are prone to deflection due to centrifugal force. Moreover, the spacers are usually made of metal or engineering plastic. Metal spacers are prone to dry friction with the steel balls, resulting in indentations, peeling, or micro-cracks. Engineering plastic spacers are not strong enough and are prone to deformation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 The present invention provides an embodiment of a steel ball turntable support assembly, comprising a steel ball turntable body 1, an outer ring 2, an inner ring 3, and a steel ball body 9. The steel ball turntable body 1 includes an outer ring 2 and an inner ring 3, and the inner ring 3 is disposed inside the outer ring 2.

[0023] The inner ring 3 and the outer ring 2 are respectively provided with a second mounting hole 6 and a first mounting hole 5 at the top edge of the top surface. The second mounting hole 6 and the first mounting hole 5 are distributed in a concentric circle structure around the main body of the steel ball turntable 1, and are used to fix the rotating component and the supporting component respectively.

[0024] The inner circumferential surface of the outer ring 2 and the outer circumferential surface of the inner ring 3 are both provided with raceways 8, and steel ball bodies 9 are evenly arranged between the raceways 8.

[0025] When the outer ring 2 is subjected to external force, the steel ball body 9 rolls in the raceway 8. The raceway 8 guides the steel ball body 9 to roll along the circumference, and evenly distributes the radial and axial loads between the outer ring 2 and the inner ring 3, causing the inner ring 3 to rotate.

[0026] The steel ball bodies 9 are evenly separated by isolation blocks 10. Each side of the isolation block 10 is provided with a ball socket 14, and the steel ball bodies 9 are in contact with the inner arc surface of the ball socket 14.

[0027] The interior of the ball socket 14 is evenly distributed with 6 sets of oil grooves 15, and the oil grooves 15 are distributed in a concentric circle structure about the ball socket 14;

[0028] An oil inlet 16 is provided on the inner ring 3, and the oil inlet 16 is connected to the raceway 8. An oil inlet channel 17 is provided inside the oil inlet 16.

[0029] Lubricating oil is injected through the oil inlet 16. The lubricating oil diffuses to the surface of the steel ball body 9 through the oil groove 15 in the ball socket 14 of the isolation block 10, forming a lubricating film and reducing the wear of the steel ball body 9.

[0030] The inside of the oil inlet channel 17 is equipped with a ball stop 19 through a return spring 18, and a sealing ring 20 is provided at the inlet of the oil inlet channel 17;

[0031] When lubricating oil is injected through the oil inlet 16, the oil pressure pushes the plug ball 19 to compress the return spring 18. The lubricating oil enters the raceway 8 through the oil inlet channel 17. After the oil injection stops, the return spring 18 pushes the plug ball 19 to reset, which, together with the sealing ring 20, prevents lubricating oil leakage and the intrusion of external impurities.

[0032] Guide grooves 23 are provided on both sides of the oil inlet channel 17, and guide blocks matching the guide grooves 23 are provided on both sides of the plug ball 19.

[0033] The movement trajectory of the ball stopper 19 is restricted so that it can only move back and forth along the axial direction of the oil inlet channel 17, i.e., the center line of the oil inlet 16, to prevent the ball stopper 19 from tilting or deviating under oil pressure.

[0034] The oil inlet end of the oil filling port 16 is provided with a cap 21, and a sealing plug 22 is provided at the end of the cap 21 near the oil filling port 16 to seal the oil filling port 16 when the oil filling is completed.

[0035] Each of the isolation blocks 10 is composed of metal reinforcing members 12 and polymer plastic 11, with the polymer plastic 11 wrapped around the outside of the metal reinforcing members 12.

[0036] The polymer plastic 11 absorbs vibration and reduces the collision noise of the steel ball body 9, while maintaining self-lubrication and preventing electrochemical corrosion between different metals. The metal reinforcement 12 is supported by aluminum alloy, providing compressive and deformation resistance, and preventing the polymer plastic 11 from creeping or breaking under high load.

[0037] The interior of the metal reinforcing member 12 is embedded with a miniature permanent magnet 13, which magnetically attracts the steel ball body 9 to prevent the steel ball body 9 from falling out of the ball socket 14 of the isolation block 10 when it is running at high speed or vibrating, thereby improving stability.

[0038] An annular groove 7 is provided along the circumferential direction at the outer edge of the inner ring 3, and a sealing strip 4 is embedded in the annular groove 7. The sealing strip 4 forms a sealing contact with the inner surface of the outer ring 2.

[0039] The sealing strip 4 fits tightly against the inner surface of the outer ring 2 to form an annular sealing barrier, preventing dust, moisture, metal shavings and other impurities from entering the raceway 8 and the steel ball body 9 area from the gap between the inner ring 3 and the outer ring 2, while preventing the lubricating oil in the raceway 8 from leaking outward.

[0040] Working Principle: In this embodiment, the main body 1 of the steel ball turntable consists of an outer ring 2, an inner ring 3, a raceway 8, and a steel ball body 9. The outer ring 2 and the inner ring 3 form a structure that can rotate relative to each other through the steel ball body 9 and the raceway 8. When the outer ring 2 is subjected to external force, the steel ball body 9 rolls in the raceway 8. The raceway 8 guides the steel ball body 9 to roll along the circumference, evenly distributing the radial and axial loads between the outer ring 2 and the inner ring 3, causing the inner ring 3 to rotate. The isolation blocks 10 are evenly distributed between the steel ball bodies 9. The ball sockets 14 of the isolation blocks 10 make rolling contact with the steel ball bodies 9. The core of the isolation blocks 10 is a metal reinforcing member 12, and the outside is wrapped with polymer plastic 11, combining the high strength of metal and the good properties of polymer plastic 11. The toughness, elasticity, wear resistance, and corrosion resistance significantly improve the strength, load-bearing capacity, and service life of the isolation block 10. The miniature permanent magnets 13 embedded in the metal reinforcement 12 magnetically attract the steel ball body 9, maintaining its stable arrangement and preventing the steel ball body 9 from shifting due to centrifugal force during high-speed rotation. In addition, lubricating oil is injected through the oil inlet 16, and the oil pressure pushes the ball block 19 to compress the return spring 18. The lubricating oil enters the raceway 8 through the oil inlet channel 17. After the oil injection stops, the return spring 18 pushes the ball block 19 to reset. The sealing ring 20 prevents lubricating oil leakage and the intrusion of external impurities. The lubricating oil diffuses to the surface of the steel ball body 9 through the oil groove 15 in the ball socket 14 of the isolation block 10, forming a lubricating film and reducing the wear of the steel ball body 9.
