Abstract
Description
Technical Field
[0001] The utility model relates to a sprocket with replaceable teeth, which is suitable for a chain bucket type elevator. Background Art
[0002] At present, the domestic cement industry is developing towards large-scale, energy-saving, environmentally friendly and efficient. Due to the construction of large-scale production lines, large conveying capacity, high lifting height and reliable conveying equipment are required to adapt to it. The specifications of the domestic chain bucket elevators are getting bigger and bigger, and the sprocket design is also getting bigger and bigger. Generally, the sprockets are divided into three types: integral sprocket, split sprocket and slice sprocket.
[0003] Integral sprocket: easy to process, high strength, mainly used for sprockets with smaller diameters, but inconvenient to maintain, increasing the cost of use, and replacement and disassembly can easily damage the main shaft and bearings; Split sprocket: relatively easy to maintain and transport; but when replacing the rim, the chain must be removed; Slice sprocket: easy to maintain, when replacing the rim, you only need to dismantle the rim in pieces to replace it, but the processing technology is complicated and the cost is high. Summary of the invention
[0004] The purpose of the utility model is to solve the problems in the prior art and to provide a sprocket with replaceable teeth, which has a simple structure, low cost and is easy to replace.
[0005] To achieve the above-mentioned purpose, the utility model proposes a sprocket with replaceable teeth, comprising a sprocket core, a plurality of tooth components I and a plurality of tooth components II, wherein the periphery of the sprocket core is integrally formed with tooth components II arranged evenly at intervals, and the space between two adjacent tooth components II constitutes an accommodating groove, each of the accommodating grooves is provided with a detachably connected tooth component I, a tooth groove is provided on the tooth component I, and the tooth component I parts on both sides of the tooth groove are tooth constituting parts respectively, and the tooth component II and the two tooth constituting parts adjacent thereto constitute a sprocket tooth body.
[0006] Preferably, a positioning body is provided in the accommodating groove, and a positioning groove matching with the positioning body is provided on the tooth component I, and the positioning body is detachably fixedly connected to the positioning groove via a pin shaft.
[0007] Preferably, the positioning body is interference fit with the positioning groove, and the pin shaft is interference fit with the positioning body and the pin hole on the tooth component I.
[0008] Preferably, the groove surface of the tooth groove is quenched to form a wear-resistant layer.
[0009] Beneficial effects of the utility model: The utility model inserts the tooth component I into the corresponding receiving groove and installs the connecting pin shaft in place with a hydraulic tool. When the tooth component I is disassembled on site, the tooth component I can be replaced without removing the chain. The connecting pin shaft is pressed out with a hydraulic tool, and the corresponding tooth component I can be disassembled, and a new tooth component I is replaced at the same time. Repeat this operation to complete the replacement of the sprocket. Since the application does not replace the entire sprocket tooth body, the cost is greatly reduced. Compared with the prior art, it can be simple in structure, low in cost, and easy to replace.
[0010] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 3 It is a partial structural schematic diagram of a sprocket with replaceable teeth of the utility model.
[0014] In the figure: 1-sprocket core, 2-tooth component I, 3-tooth component II, 4-accommodating groove, 5-tooth groove, 6-tooth forming part, 7-positioning body, 8-positioning groove, 9-pin shaft, 10-wear-resistant layer. DETAILED DESCRIPTION
[0015] See also Figure 1 , Figure 2 The utility model is a sprocket with replaceable teeth, comprising a sprocket core 1, a plurality of tooth components I2 and a plurality of tooth components II3. The periphery of the sprocket core 1 is integrally formed with tooth components II3 evenly spaced. The space between two adjacent tooth components II3 constitutes an accommodating groove 4. The accommodating groove 4 is provided with a detachably connected tooth component I2. The tooth component I2 is provided with a tooth groove 5. The tooth component I2 parts on both sides of the tooth groove 5 are tooth forming parts 6 respectively. The tooth component II3 and the two adjacent tooth forming parts 6 constitute a sprocket tooth body.
[0016] See also Figure 2 , Figure 3 A positioning body 7 is provided in the accommodating groove 4, and a positioning groove 8 matching with the positioning body 7 is provided on the tooth member I2. The positioning body 7 is detachably fixedly connected to the positioning groove 8 through a pin shaft 9.
[0017] The positioning body 7 is interference fit with the positioning groove 8, and the pin shaft 9 is interference fit with the positioning body 7 and the pin hole on the tooth component I2.
[0018] The groove surface of the tooth groove 5 is formed into a wear-resistant layer 10 through quenching treatment.
[0019] Working process of this utility model:
[0020] During the operation of the sprocket with replaceable teeth of the utility model, the tooth component I2 is inserted into the corresponding receiving groove 4, and the connecting pin is installed in place with a hydraulic tool. When the tooth component I2 is disassembled on site, the tooth component I2 can be replaced without removing the chain. The connecting pin is pressed out with a hydraulic tool, and the corresponding tooth component I2 can be disassembled, and a new tooth component I2 is replaced at the same time. This operation is repeated to complete the replacement of the sprocket. Since the application does not replace the entire sprocket tooth body, the cost is greatly reduced. Compared with the prior art, it can be simple in structure, low in cost, and easy to replace.
[0021] Compared with the segmented sprocket, the present invention has a relatively simple processing technology, and the heat treatment of the wheel rim is more convenient. Each tooth can be quenched without rotation, because each tooth is the same and can be stacked together for quenching.
[0022] The weight of the segmented wheel rim is much greater than the weight of a single tooth. In this application, no lifting tools are needed when replacing the sprocket teeth, making maintenance more convenient.
[0023] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
