Problems solved by technology
The existing conventional seals are complicated to install, and it is difficult to ensure reliable sealing when the reamer shakes
Especially in the sealing installation, it is usually necessary to open installation grooves on the end face of the original reamer shaft seat and the end face of the drive device (such as a gearbox), which destroys the original structure and easily leads to deterioration of the stress on the structural parts, resulting in Stress concentration, lack of strength
At the same time, improving the structure (opening installation grooves, etc.) is time-consuming and labor-intensive, especially inconvenient to operate on the job site, and the installation and replacement of the seal is time-consuming and laborious

The invention provides a seal for transitional connection, which includes a U-shaped sealing body with an inward opening and a U-shaped sealing body connected with it with an outward opening; the U-shaped sealing body includes a buffer part and elastic buffer parts on both sides A connecting part; a sealed cavity is formed between the two U-shaped sealing bodies. The invention creates a retaining ring at the connection between the seal and the structure, which can effectively ensure the reliability of the gasket at the connection installation. At the same time, the cross section of the invention is equivalent to a back-to-back structure, which strengthens the structural strength of the seal. Even if no fabric or skeleton is added inside the seal, the bend is not easily damaged, the manufacturing process is simple, and the cost is low.
Description
technical field [0001] The invention belongs to the technical field of seals for dredgers, and in particular relates to a seal for transitional connections. Background technique [0002] Cutter suction dredger is a kind of ship widely used in beach dredging projects. It uses the front end of the suction pipe to install a rotary reamer device around the suction pipe to cut and stir the river bottom sediment, and then through suction dredging The tube transports the hoisted sediment material to the sediment material accumulation field with the help of powerful pump force, and the processes of dredging, transporting and unloading can be completed continuously at one time. In fact, the reamer part and the device driving the reamer also need to be sealed to prevent seawater from intruding into the equipment, and at the same time prevent the oil in the equipment (hydraulic oil in the case of hydraulic drive / gear oil in gear box drive) ) seeps into seawater causing pollution. T...
