Description

Technical Field

[0001] This utility model relates to the field of bearings, and in particular to a spliced ​​high-strength lightweight nylon cage. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the standards and demands for new energy bearings are also increasing. The ability of bearings to maintain a long lifespan under high-speed conditions has become a crucial indicator. The core of a new energy vehicle is the motor, and the bearing is a key supporting component of the motor rotor. Among these components, the bearing cage is vital for the long-term stable operation of the bearing. Currently, there are spliced ​​cages, such as the spliced ​​needle roller bearing cage disclosed in patent document CN205715286U. However, this requires combining multiple support rings and isolators, resulting in too many structural components and low installation efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a spliced ​​high-strength lightweight nylon cage, which has a lighter overall structure, higher installation efficiency, and improved stability and lifespan compared to ordinary spliced ​​cages. It can work for a long time under extreme conditions such as high speed, high temperature, and heavy load.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a spliced ​​high-strength lightweight nylon retainer, including a first side ring plate and a second side ring plate;

[0005] The first side ring plate and the second side ring plate are coaxially opposite each other.

[0006] A plurality of roller slots are distributed around the first side ring plate and the second side ring plate, and the roller body is located in the roller slot;

[0007] The first side ring plate and the second side ring plate are respectively provided with mutually connected limiting members between the roller clamping positions.

[0008] This design uses a first side ring plate and a second side ring plate to form a cage. The limiting component serves as both a splicing structure and a roller locking mechanism, i.e., a ball groove that limits the roller body.

[0009] Preferably, the two sides of the limiting member have an outwardly expanding V-shaped structure, which facilitates the guidance of grease into the raceway.

[0010] Preferably, the outer surface of the limiting member is axially provided with an oil groove, the bottom of the oil groove being through-hole, and the first side ring plate and the second side ring plate are respectively provided with grease injection ports at one end of the oil groove. This facilitates grease injection and allows the grease to enter the raceway more smoothly. Providing grease injection ports only on one side prevents it from flowing out from the other side, and the through-hole design of the oil groove bottom facilitates guiding the grease into the raceway.

[0011] Preferably, the limiting members of the first side ring plate and the second side ring plate are engaged one-to-one, facilitating a one-to-one connection.

[0012] Preferably, the limiting member includes an inner plate assembly disposed on the first side ring plate and an outer plate assembly disposed on the second side ring plate. The inner plate assembly includes two inner connecting plates with their outer sides unfolded, and the outer plate assembly includes two outer connecting plates with their outer sides unfolded. The two inner connecting plates are correspondingly attached to the inner sides of the outer connecting plates, and the outer connecting plates and the inner connecting plates are interlocked with each other. This facilitates the connection and assembly of the two components.

[0013] Preferably, the outer surface of the inner connecting plate is provided with a bayonet, and the inner surface of the outer connecting plate is provided with a wedge-shaped protrusion that matches the bayonet. As the first side ring plate and the second side ring plate approach each other, the wedge-shaped protrusion gradually engages with the bayonet. This allows for rapid assembly.

[0014] Preferably, the first and second side ring plates are each provided with a plurality of perforations. This achieves a lightweight design while ensuring sufficient strength.

[0015] Preferably, all components are made of nylon. It is heat-resistant, durable, has a lower coefficient of friction, and results in less relative motion damping.

[0016] The beneficial effects of this utility model are:

[0017] The overall structure is lighter, the installation efficiency is high, and the stability and lifespan are improved compared to ordinary spliced ​​cages. It can work for a long time under extreme conditions such as high speed, high temperature and heavy load, and the reliability is very good. Attached Figure Description

[0023] Example

[0024] like Figure 1 As shown, the spliced ​​high-strength lightweight nylon retainer includes a first side ring plate 1 and a second side ring plate 2.

[0025] The first side ring plate 1 and the second side ring plate 2 are coaxially opposite each other.

[0026] A plurality of roller slots 3 are distributed around the first side ring plate 1 and the second side ring plate 2, and the roller body 4 is located in the roller slots 3.

[0027] The first side ring plate 1 and the second side ring plate 2 are respectively provided with mutually connected limiting members 5 between the roller clamping positions 3.

[0028] This design uses a first side ring plate 1 and a second side ring plate 2 spliced ​​together to form a retainer. The limiting member 5 serves as both a splicing structure and a roller locking position 3, which is a ball groove that limits the roller body 4.

[0029] With fewer components, the overall strength after assembly is higher, it is easier to assemble, and it has better stability.

[0030] The limiting member 5 has a figure-eight shape on both sides that gradually expands outwards, which facilitates the guidance of grease into the raceway.

[0031] The outer surface of the limiting member 5 is axially provided with an oil groove, the bottom of which is through-hole. The first side ring plate 1 and the second side ring plate 2 are respectively provided with grease inlets 10 at one end of the oil groove. This facilitates grease injection and allows the grease to enter the raceway more smoothly. The grease inlet 10 is only provided on one side to prevent it from flowing out from the other side, and the through-hole design of the oil groove bottom facilitates guiding the grease into the raceway.

[0032] The limiting members 5 of the first side ring plate 1 and the second side ring plate 2 are engaged one-to-one, facilitating a one-to-one connection.

[0033] The limiting component 5 includes an inner plate assembly 6 disposed on the first side ring plate 1 and an outer plate assembly 7 disposed on the second side ring plate 2. The inner plate assembly 6 includes two inner connecting plates with their outer sides unfolded, and the outer plate assembly 7 includes two outer connecting plates with their outer sides unfolded. The two inner connecting plates are correspondingly attached to the inner sides of the outer connecting plates, and the outer connecting plates and the inner connecting plates are interlocked. This facilitates the connection and assembly of the two components. In fact, the oil tank is composed of the inner plate assembly 6 and the outer plate assembly 7 in a one-to-one correspondence.

[0034] The outer surface of the inner connecting plate is provided with a bayonet 8, and the inner surface of the outer connecting plate is provided with a wedge-shaped protrusion 9 that matches the bayonet 8. As the first side ring plate 1 and the second side ring plate 2 approach each other, the wedge-shaped protrusion 9 gradually engages with the bayonet 8. This allows for rapid assembly.

[0035] The first side ring plate 1 and the second side ring plate 2 are each provided with a plurality of perforations 11. The design is lightweight while ensuring sufficient strength.

[0036] All components are made of nylon. It is heat-resistant, durable, has a lower coefficient of friction, and results in less relative motion damping.

[0037] The beneficial effects of this utility model are:

[0038] The overall structure is lighter and easier to install. Its stability and lifespan are improved compared to ordinary spliced ​​cages. It can work for a long time under extreme conditions such as high speed, high temperature and heavy load, and its reliability is very good.

[0039] The technical features of the above embodiments can be combined in any way.
