Description

Technical Field

[0001] This utility model relates to the field of warp knitting machine technology, specifically to a crankshaft for a warp knitting machine. Background Technology

[0002] Warp knitting machines are knitting machines that use chemical fiber filaments (such as polyester, nylon, spandex and other filaments) as raw materials to weave clothing fabrics, underwear fabrics, swimwear fabrics, curtain fabrics, home textile fabrics, industrial fabrics and so on. Because warp knitting machines only use warp threads to weave fabrics, they have the advantages of short production process, high production efficiency, many fabric varieties, low investment cost and low energy consumption, and are highly favored by the textile industry.

[0003] The crankshaft is the most important transmission component on a warp knitting machine. Due to the long length of warp knitting machines, the crankshaft is processed in sections, requiring a large number of crankshafts, each of which needs to be mounted on a connecting rod holder. As a transmission component, the crankshaft requires lubrication during operation. As a result, each connecting rod holder needs to be specially designed with oil passages for crankshaft lubrication, resulting in a large number of oil pipes and making the entire connecting rod holder and the internal structure of the machine very bulky. Utility Model Content

[0004] The purpose of this invention is to solve the problem of cumbersome crankshaft installation, where each section must be installed together with the connecting rod bracket, and each crankshaft section requires an independent oil pipe for lubrication.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A crankshaft for a warp knitting machine, characterized in that: it is composed of several crankshaft bodies connected together, one end of each crankshaft body is a first connecting journal, the other end of each crankshaft body is a second connecting journal, the first and second connecting journals of adjacent crankshaft bodies are fixedly connected by a connecting assembly, each of the several crankshaft bodies is provided with a lubricating oil passage, the several lubricating oil passages are interconnected, a positioning assembly is provided between the connection points of adjacent crankshaft bodies, and a sealing assembly is provided at the connection points of the lubricating oil passages.

[0007] A further improvement is that the coupling assembly includes several fastening bolts and corresponding fastening nuts. The end faces of the first and second coupling journals are provided with bolt holes corresponding to the fastening bolts. The fastening bolts pass through the bolt holes and are threadedly fixed to the fastening nuts.

[0008] A further improvement is that a washer is provided between the fastening nut and the second coupling journal.

[0009] A further improvement is that the positioning component consists of several positioning pins.

[0010] A further improvement is that the end faces of the first and second coupling journals are each provided with a plurality of positioning pin holes corresponding to the positioning pins, and the positioning pins are inserted into the positioning pin holes.

[0011] A further improvement is that the sealing component is a sealing ring, and the end faces of the first and second coupling journals are provided with sealing grooves on the outer periphery of the lubrication oil passage, and the sealing ring is embedded in the sealing groove.

[0012] A further improvement is that the crankshaft body can be detachably installed with several counterweights.

[0013] A further improvement is that the counterweight can be detachably mounted on the crankshaft body via locking bolts.

[0014] Compared with existing technologies, the above technical solution has the following advantages:

[0015] The crankshaft is composed of several crankshaft bodies connected together. All crankshafts are separated from the connecting rod frame and adjacent crankshaft bodies are connected by bolts. The overall installation and disassembly become very convenient and quick, the whole system operates more efficiently, and there is no need to process many oil pipes to provide lubrication for the crankshaft, which effectively reduces costs.

[0016] The combination of a sealing ring and a sealing groove can achieve a better sealing effect and prevent lubricating oil leakage at the connection.

[0026] See Figures 1-6 As shown, the technical solution adopted in this specific embodiment is: a crankshaft of a warp knitting machine, which is composed of several crankshaft bodies 1 connected together. One end of the crankshaft body 1 is a first connecting journal 3, and the other end of the crankshaft body 1 is a second connecting journal 4. The first connecting journal 3 and the second connecting journal 4 of adjacent crankshaft bodies 1 are fixedly connected by a connecting assembly 5. Each of the several crankshaft bodies 1 is provided with a lubricating oil passage 8, and the several lubricating oil passages 8 are connected. A positioning assembly 9 is provided between the connection points of adjacent crankshaft bodies 1, and a sealing assembly is provided at the connection points of the lubricating oil passages 8.

[0027] The coupling assembly 5 includes several fastening bolts 51 and corresponding fastening nuts 52. The end faces of the first coupling journal 3 and the second coupling journal 4 are provided with bolt holes 54 corresponding to the fastening bolts 51. The fastening bolts 51 pass through the bolt holes 54 and are threadedly fixed to the fastening nuts 52.

[0028] A washer 53 is provided between the fastening nut 52 and the second coupling journal 4. The washer 53 can protect the journal during tightening and prevent the fastening nut 52 from scratching it.

[0029] The positioning component 9 consists of several positioning pins 91.

[0030] The first and second coupling journals 3 and 4 each have several positioning pin holes 92 corresponding to the positioning pins 91 on their end faces. The positioning pins 91 are inserted into the positioning pin holes 92. By using the positioning pins 91 in conjunction with the positioning pin holes, the phase angle accuracy between two adjacent shafts is ensured during the coupling process, thereby greatly improving the transmission accuracy of the crankshaft.

[0031] The sealing component is a sealing ring 11. A sealing groove 10 is provided on the end faces of the first coupling journal 3 and the second coupling journal 4 on the outer periphery of the lubrication oil passage 8, and the sealing ring 11 is embedded in the sealing groove 10. The cooperation between the sealing ring and the sealing groove provides a better seal, preventing lubricating oil leakage at the connection point.

[0032] The crankshaft body 1 is detachably mounted with several counterweights 6.

[0033] The counterweight 6 is detachably mounted on the crankshaft body 1 via locking bolts 7. This detachable mounting via bolts allows for easy disassembly and reassembly of the counterweight 6 as needed.

[0034] The working principle of this utility model is as follows: In use, the crankshaft is composed of several crankshaft bodies connected together. All crankshafts are separated from the connecting rod frame, bolted together, and then assembled on the middle wall plate. The separate lubrication channels for each segment are eliminated, and the lubrication channels of the individual crankshaft bodies are connected into one channel. Instead, oil enters from the first crankshaft body and exits from the last crankshaft body. Only the lubrication pipes connected to the first and last crankshaft bodies are needed to provide lubrication for the entire crankshaft. The bolted connection makes overall installation and disassembly very convenient and quick, the entire system operates more efficiently, and there is no need to process many oil pipes to provide lubrication for the crankshaft, effectively reducing costs. The combination of sealing rings and sealing grooves can provide better sealing and prevent lubrication leakage at the connection. The cooperation of locating pins and locating pin holes can ensure the accuracy of the connection and ensure the phase angle accuracy requirements of the connected crankshaft bodies, thereby greatly improving the transmission accuracy of the crankshaft.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions provided are merely illustrative of the principles of this utility model.
