Abstract

The invention relates to a ratchet clutch load-equalizing method which comprises the steps of optimizing the structure of a pawl, wherein the pawl is provided with a pawl body, one end of the head of the pawl body is of a plane structure, one end of the tail of the pawl body is of an arc structure, the pawl body extends in an arc shape from the head of the pawl body to the tail of the pawl body, and the thickness is gradually increased; and enabling the pawl to be made of a spring steel material, so that the bearing capacity of a ratchet clutch is improved. According to the ratchet clutch load-equalizing method provided by the invention, through optimizing the structure and material of the pawl, the load-equalizing performance between pawls of the ratchet clutch can be improved, so that the overall bearing capacity of the ratchet clutch is improved.

Description

technical field [0001] The application belongs to the technical field of ratchet clutches, in particular to a method for equalizing loads of ratchet clutches. Background technique [0002] Marine gas turbines generally use an electric starter as a starting device to provide power to the ship as quickly as possible. After the gas turbine is started, the electric starter is not needed to continue to work, so a ratchet clutch is provided on the starting transmission chain to ensure that the gas turbine is disconnected from the electric starter after the start. However, the output load of the switched reluctance electric starter used by the gas turbine is unstable, and there is an excessive impact load, which causes the pawl fracture failure of the ratchet clutch on the starting transmission chain due to insufficient carrying capacity, which seriously affects the use. [0003] Such as figure 1 and figure 2 Shown is the structural diagram of the ratchet clutch used in the pri...
