A cutting tool for machining rov propeller profile gear

Abstract

The present invention specifically relates to a tool for processing profiled gears of ROV propellers, comprising a tool holder and a hob disposed on the tool holder, the hob comprising a plurality of continuous linearly arranged hobbing teeth, any of the hobs The tooth height of the tooth is 1.65cm, wherein, the root height is 0.975cm, and the addendum height is 0.675cm; the tooth thickness of any one of the hobbing teeth is 0.946cm, the radius of the addendum circle is 0.324cm, and the radius of the root circle is 0.163cm, the lead angle of the tooth thread is 1°7′18″, and the direction of rotation is right-handed; the tooth pitch of two adjacent hobbing teeth is 1.885cm; the modulus of the hob is 0.6, the number of grooves is 12, and the pressure The angle is 20°; the helix angle of the edge groove is 0°, and the direction of rotation is a straight groove; the base circle radius is 0.823cm, and the base circle rise angle is 20°1'49"; the ROV propeller modification gear is composed of the Hob gear hobbing is obtained. Through the technical solution provided by the invention, the processing and manufacturing of the modified gear of the ROV propeller can be realized.

Description

technical field [0001] The invention relates to the technical field of ROV propellers, in particular to a tool for processing profiled gears of ROV propellers. Background technique [0002] ROV (Remote Operated Vehicle) is an underwater robot used for underwater observation, inspection and construction. The micro ROV has its own energy source and is smart to operate. It carries a miniature camera and sensors, which can expand the observation range of the manned submersible, and can work in small dangerous areas where the manned submersible is inconvenient or inaccessible. [0003] The driving of ROV mainly relies on the ROV propeller installed on both sides and tail of ROV. There are many places where gears are used in ROV propeller, such as the planetary gear on the planetary reducer, and the shaft of the ROV propeller motor is used to communicate with the planetary reducer. The sun gear connected, and the ring gear set on other connected parts, etc. The gears used in ROV...

AI Technical Summary

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
