Embodiment Construction

[0032] The present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0033] Non-limiting and non-exclusive embodiments will be described with reference to the following drawings, wherein like reference numerals refer to like parts unless specifically stated otherwise.

[0034] Such as Figure 1-5 A gear stopper ferrule device is shown, which is applied to the clamping of the engine gear train, including ferrule 2, which consists of two cylinders, one large and one small, to form a central coaxial boss, and there are holes running through it. The stepped hole on the end face is a large hole 22 in the large cylinder section and a small hole 23 in the small cylinder section. An annular groove 6 is provided at the junction of the two cylinder...

Abstract

The invention discloses a gear anti-rotating ferrule device. The gear anti-rotating ferrule device is mainly applied to clamping of an engine gear train. The gear anti-rotating ferrule device comprises a ferrule, a balance block and a positioning pin. A center-coaxial boss is formed by a large cylinder and a small cylinder, a stepped hole penetrating through the upper end face and the lower end face of the boss is formed, an annular groove is formed in the joint of the two cylinders, an axial positioning hole is formed in the joint surfaces of the two cylinders, and an opening is formed in theside wall of the large cylinder. The balance block is arranged in the annular groove and rotationally connected with the ferrule. The balance block and the annular groove are connected to the position of the positioning hole through a pin hole. The gear anti-rotating ferrule device has the beneficial effects of being simple in structure, easy and convenient to operate and high in universality, saving labor and the like.

Description

technical field [0001] The invention relates to the technical field of assembly of engine accessories, in particular to a gear locking sleeve device and a method for using the same. Background technique [0002] When assembling the engine gear train, the gear train will follow the rotation during the torque-up process, which may easily lead to failure of the torque-up torque or substandard tightening torque, seriously affecting the power and aerodynamic performance of the engine. A common method is to block the meshing sides of the two gears with a steel bar to stop the rotation. This method usually requires one hand to hold the steel bar all the time. Or use the tooth-shaped clamp block in combination with the baffle plate to stop the rotation, or use the hook bar to hook the through hole of the spoke to stop the rotation. These methods cannot be widely used because of inconvenient operation or poor versatility. [0003] The disclosure of the above background technical con...
