Problems solved by technology
For serialized products similar to centrifugal water pumps, many kinds of coupling guards are needed to meet the needs of different lengths and heights of couplings, which increases the types of materials, production management and products. management complexity
In order to reduce investment (such as mold cost, the cost of accessories required for corresponding processing, etc.) and reduce the number of coupling guards, the current technical solution for non-metallic material coupling guards is to realize the length by cutting before assembly The adjustment of the direction size, that is, to manufacture the coupling guard according to the longest size, and cut it into different lengths of the coupling guard according to the needs in actual production; but this will cause waste of materials and increase assembly time, reducing production efficiency
The current technical solution for the metal material coupling guard is to divide the coupling guard into two parts; design short-circuit parts of different lengths to adjust the size in the length direction; but due to the large number of short-connects, it also causes production Increased costs and product management costs

The invention relates to a coupling protective cover. The coupling protective cover comprises a fixed connecting part, a flexible connecting part and a bracket; the fixed connecting part includes a driven end and a first connecting end; the flexible connecting part has a second connecting end; the driven end of the fixed connecting part is connected with driven mechanical equipment; the first connecting end of the fixed connecting part is connected with the second connecting end of the flexible connecting part; and the fixed connecting part is fixed through the bracket. The coupling protective cover improves the production efficiency and reduces the product cost due to capability of adjusting the length.
Description
technical field [0001] The invention relates to a coupling guard, in particular to a variable-length coupling guard. Background technique [0002] The coupling guard is a protective device installed on mechanical equipment to protect the operator's personal safety. At present, various coupling guards are widely used in various fields of industry. However, the shape and geometric dimensions of the current coupling guards are fixed. For some cases (such as non-serialized products), a coupling guard with fixed shape and geometry is reasonable. But for the case of serialized products, such as the end suction centrifugal pump driven by the prime mover (the pump shaft of the water pump and the drive shaft of the prime mover are connected together through a coupling, so that the output power of the prime mover is transmitted to the pump shaft of the water pump Couplings above), different water pump pump heads (the central height of the pump shaft and / or the outer dimensions of t...
