Description

Technical Field

[0002] Chinese patent document CN209577062U discloses an engineering machinery transmission device, including a housing, a ratchet fixed shaft, a stepped shaft, and an annular shaft cover. A support bearing chamber is opened at one end of the housing, and a motor shaft hole is opened at the other end. A ratchet fixed chamber is axially opened at the left end of the stepped shaft, and a large gear is sleeved on the right end. The left end of the stepped shaft is fixed in the support bearing chamber through a support bearing, and the middle part of the stepped shaft is fixed to the housing through an annular shaft cover. The ratchet fixed shaft is used in conjunction with the ratchet on the stepped shaft to separate the operation of the auxiliary starting transmission device from the operation of the high-speed main shaft. The added electromagnet can actively separate the pawl from the ratchet part when the electromagnet is energized, and the passive separation of the pawl and the ratchet part is converted into active separation, which can reduce the friction between the pawl and the ratchet part, thereby extending the service life of the ratchet and the pawl.
