Problems solved by technology

[0006] Regardless of the above-mentioned direct connection structure, it is a rigid connection structure, and it will cause damage to the diesel engine or water pump when the load or impact changes suddenly.
In severe cases, broken shafts or teeth will occur, causing the entire unit to fail to work normally. This is the most common and fatal defect of the direct-connected diesel engine water pump unit

Abstract

The invention relates to a soft direct-connection structure of a diesel engine pumping unit. The soft direct-connection structure of the diesel engine pumping unit comprises a power output plate, a power input plate and more than two elastic belt sections, wherein the power output plate is fixedly connected with a flywheel of a diesel engine, the power input plate is fixedly connected with a main shaft of a water pump, and more than two elastic belt sections are uniformly fixedly arranged between the power output plate and the power input plate circumferentially. The power output plate and the power input plate are connected by the elastic belt sections so that the soft direct-connection structure has the advantages of capacity of rigid connection and cushion on belt transmission, can not only reduce the installation precision requirements of the diesel engine and the water pump, but also can realize the high-efficiency power transfer and can cushion impaction force in a running process of the diesel engine, improves the stability of the power transfer of the diesel engine, prevents the damage on the diesel engine and the water pump due to load or the impact force, reduces the probability of shaft breakage or tooth breakage, and improves the reliability of regular operation of a whole machine set.

Description

【Technical field】 [0001] The invention relates to a diesel engine water pump unit, in particular to a flexible direct connection structure of the diesel engine water pump unit. 【Background technique】 [0002] Among the existing water pump units, according to power, they can be divided into motor water pump units, diesel engine water pump units and gasoline engine water pump units, and the most commonly used ones are diesel engine water pump units. According to the structural shape of the power-driven water pump, it is divided into belt drive and direct-connected butt drive. Among them, the belt drive is characterized by: stable transmission, low installation requirements for diesel engine and water pump in the unit, and long service life of diesel engine and water pump. The transmission efficiency is relatively low and the volume is large. The direct-coupled butt joint drive has compact structure and high transmission efficiency, but it has high requirements for the install...
