[0002] Chain wheel is a kind of wheel with embedded tooth type buckle chain tooth, is used to be engaged with the block on the chain or cable of accurate pitch, to transmit power or movement. Chain wheel is usually composed of three parts of gear ring, wheel hub and spoke, wherein gear ring is the working part of chain wheel, and its tooth shape design needs to ensure that chain can smoothly enter and exit engagement. Chain wheel tooth shape is generally composed of three circular arcs and a straight line, simply referred to as three circular arc straight line tooth shape, which is easy to process and can meet the transmission requirements.

[0003] In practical application, chain wheel realizes transmission function by cooperating with chain. However, long-time use will cause chain wheel wear. In order to slow down the wear, the method of adding lubricant is usually adopted. But manual addition of lubricant is sometimes difficult to accurately control the amount of addition, which is easy to cause excessive addition, thereby causing waste of lubricant. Such waste not only increases operating cost, but also may cause negative impact on environment. SUMMARY

[0004] The main purpose of the utility model is to provide a kind of high-strength wear-resistant chain wheel structure, which can effectively solve the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0007] The side wall of the embedded slot is provided with a plurality of protruding parts, an installation hole is formed in the end face of each protruding part, an inner support ring is embedded in the slot of the embedded slot, and a recessed groove matched with the protruding part is formed in the inner support ring, a connecting hole matched with the installation hole is formed in the recessed groove, and the support of the outer support ring is realized by the inner support ring.

[0008] A plurality of through grooves are formed in the end face of the inner support ring, and an oil storage air bag is installed in one of the through grooves, a through hole is formed in the side wall of the inner support ring, an oil injection port is inserted into the through hole, the oil injection port is connected with the oil storage air bag, and the oil injection port is realized by extruding the oil storage air bag, so as to realize the lubrication operation of the chain wheel.

[0009] As a preferred scheme of the present application, the outer support ring, the meshing tooth part and the protruding part are designed integrally, a plurality of protruding parts are annularly distributed in the inner hole of the outer support ring, the protruding part and the outer support ring are designed in arc shape at the butt joint, and the inner wall of the protruding part is designed in arc shape.

[0010] As a preferred scheme of the present application, a plurality of said through grooves are annularly distributed on the inner support ring, the through grooves are designed in a crescent shape, the edges of the through grooves are designed in an arc shape, and the oil storage air bag is designed in a crescent shape and connected to the inner support ring by an adhesive;

[0011] As a preferred scheme of the present application, the oil storage air bag is designed in an integral manner with the oil injection port, the oil injection port is connected to the inner support ring by an adhesive, the oil storage air bag internally stores an oil absorption sponge and lubricating oil, and the oil injection port is provided with a suction nozzle at a port thereof;

[0012] As a preferred scheme of the present application, the diameters of the mounting hole and the connecting hole are consistent, the edges of the mounting hole and the connecting hole are designed in an arc shape, and the mounting hole and the connecting hole are threaded holes;

[0013] As a preferred scheme of the present application, the protruding part is adapted to the recessed groove, and an anti-skid rubber gasket is arranged between the protruding part and the recessed groove, and the opening of the through hole is designed in an arc shape, and the through hole is communicated with the through groove.

[0014] Compared with the prior art, the present application has the following beneficial effects:

[0015] The design of the replacement system enables the key components of the sprocket, such as the meshing teeth and the outer support ring, to be conveniently replaced, thereby prolonging the service life of the entire sprocket structure. When the sprocket is used for a long time, the meshing teeth may fail due to wear. At this time, the entire sprocket does not need to be replaced, and only the damaged meshing teeth need to be replaced, which reduces the maintenance cost and improves the economy of the equipment.

[0016] The introduction of the oil injection lubrication system effectively solves the problems of wear and heat caused by excessive friction during the operation of the sprocket. By extruding the oil storage air bag, the lubricating oil can be uniformly sprayed on the meshing teeth and other related parts of the sprocket, forming a protective film and reducing the direct contact between the components, thereby reducing the wear rate and improving the operation efficiency of the sprocket.

[0017] The combination of the replacement system and the oil injection lubrication system makes the maintenance of the sprocket more simple and efficient. The staff can quickly replace the damaged components and lubricate the sprocket through the oil injection lubrication system, without the need for complex disassembly and recombination work, which improves the maintenance efficiency of the equipment and reduces the downtime.

[0018] The design also enhances the stability of the sprocket structure. Through the adaptation of the protruding part to the recessed groove and the installation of the anti-skid rubber gasket, the relative sliding between the components is effectively prevented, ensuring the stability and safety of the sprocket during high-speed operation. At the same time, the arc design of the through hole and the through groove also reduces stress concentration and improves the fatigue resistance of the sprocket. BRIEF DESCRIPTION OF DRAWINGS
