Problems solved by technology

The gears used in ROV thrusters in the prior art are all standard gears manufactured according to industry standards. When the gear teeth enter and disengage, impact and noise will be generated due to angular velocity fluctuations caused by gear tooth errors and load deformation. The occurrence of this phenomenon is unavoidable even if the gears are manufactured with high precision

Abstract

The invention particularly relates to a tool for machining a modified gear of an ROV propeller. The tool comprises a tool rest and a hob arranged on the tool rest. The hob comprises a plurality of hob teeth which are arranged continuously and linearly. The tooth height of each hob tooth is 1.65 cm, the tooth dedendum of each hob tooth is 0.975 cm, the tooth addendum of each hob tooth is 0.675 cm; the tooth thickness of each hob tooth is 0.946 cm, the radius of the addendum circle of each hob tooth is 0.324 cm, the radius of the dedendum circle of each hob tooth is 0.163 cm, the tooth lead angle is 1 degree 7 minutes 18 seconds, and the rotating direction is rightward; the tooth distance between every two adjacent hob teeth is 1.885 cm; the modulus of the hob is 0.6, the number of grooves of the hob is 12, and the pressure angle is 20 degrees; the helical angle of each blade groove is 0 degree, and the blade grooves are straight groove on the aspect of the rotating direction; the base circle radius is 0.823 cm, and the base circle lead angle is 20 degrees 1 minute 49 seconds; and the modified gear of the ROV propeller is obtained through gear hobbing by means of the hob. By adoption of the technical scheme, machining and manufacturing of the modified gear of the ROV propeller can be achieved.

Description

technical field [0001] The invention relates to the technical field of ROV thrusters, in particular to a tool used for machining ROV thruster trim gears. Background technique [0002] ROV (Remote Operated Vehicle) is an underwater robot used for underwater observation, inspection and construction. The mini ROV has its own energy, dexterous operation, and carries miniature cameras and sensors, which can expand the observation range of manned submersibles, and can work in small and dangerous areas that are inconvenient or inaccessible to manned submersibles. [0003] The drive of the ROV mainly relies on the ROV thrusters installed on both sides and at the tail of the ROV. There are many places where gears are used in the ROV thruster, such as the planetary gear on the planetary reducer, and the ROV thruster motor shaft is used to connect with the planetary reducer. The connected sun gear, as well as the ring gear set on other connecting parts, etc. The gears used in ROV pro...
