Embodiment Construction

[0017] Taking the reference gear helical model 1 (hereinafter referred to as the model) with a pitch circle diameter of 120 mm and a tooth width of 100 mm as an example, the design ideas and structural features of the model are described.

[0018] The maximum diameter of the outer circle of the model is set to 126mm, the involute cylindrical surface and the involute helical surface start from the base cylindrical surface, and the chamfer of the tooth top and tooth root is not greater than 0.5mm to ensure the development length of the involute. There are three tooth grooves processed on the outer cylindrical surface of the template, which are straight tooth groove 1-1, left-handed tooth groove 1-2 and right-handed tooth groove 1-3. Straight tooth grooves include one involute cylindrical surface with 0° helix angle, left-handed tooth grooves include one left-handed 15° and left-handed 30° involute helical surfaces, right-handed tooth grooves include right-handed 15° and right-han...

Abstract

The invention belongs to the technical field of precision gear testing, and discloses a reference-grade gear helix template. The invention provides a reference gear helical template which is easy to obtain high precision by generating processing method, and has an overall symmetrical structure. Slots, left-handed and right-handed gullets, axial datum toroid and radial datum cylinder, fine thread and center hole. Among them, the straight tooth groove includes one involute cylindrical surface on the opposite side of the 0° helix angle, the left-handed tooth groove includes one left-handed 15° and one left-handed 30° involute helical surface, and the right-handed tooth groove includes a right-handed 15° and a right-handed groove. Each of the 30° involute helical surfaces. The reference-grade gear helix template provided by the invention has unified design, processing and measurement datum, symmetrical structure, balanced quality, and base discs can be installed at both ends to facilitate the use of generating processing method to obtain high processing accuracy.

Description

technical field [0001] The invention belongs to the technical field of precision gear testing, and relates to a reference-level gear helix template used for the value transmission of the gear helix. Background technique [0002] The total deviation of the helical line of the gear is one of the mandatory inspection items of the gear. The standard device used to calibrate the helix measurement accuracy of gear measuring instruments is the gear helix sample. Its involute helix surface is the standard for verifying various helix instruments. It is used to transmit the parameter value of the gear helix, correct the instrument indication value, Determine the instrument indication error, etc. On April 14, 2017, the High-tech Department of the Ministry of Science and Technology of my country issued a special plan for scientific and technological innovation in the field of advanced manufacturing technology, clearly proposing to focus on "mechanical basic technology and key component...
