GRAPHIC ANALYTICAL METHOD FOR DESIGNING A CAMBLE LOCK COMPOUND

Abstract

In the complex realities of the modern industry of Ukraine, an important area of scientific and technological development is the development of new technologies for computer-aided design with increased requirements for the degree of complexity of designing structures and reducing lead times. Despite the serious pressure of the crisis in the economy and in the face of increased competition in the market, these components force us to carry out work at the most advanced technical level.

Analysis of the advantages and disadvantages of the most common types of gears in practice, technical requirements and technological capabilities in their design and manufacture at the present stage of development shows that developments in the field of creating gears with non-traditional tooth profiles are relevant. The technical solution proposed in the article relates to cylindrical gears of external gearing, the shape of the teeth of the wheels of which is formed as the envelope of the initial contour of the gear rack, and the number of teeth is assigned depending on the purpose of the mechanism, the required gear ratio and the diametrical dimensions. Such mechanisms are used in various engineering industries in the form of gear wheels of gearboxes, winches, planetary and wave transmissions, as well as working bodies of pumps, hydraulic motors, compressors and internal combustion engines with straight and helical teeth. In the oil and gas industry, gears are widely used in gearboxes of rocking machines, power drives of the main units of drilling rigs, working bodies of downhole hydraulic motors and volumetric pumps, auxiliary mechanisms.

In the work, only some basic parameters of the lock connection were developed and investigated that ensure the operability of the lock transmission.

Keywords: locking gear, locking joints, modeling of mating surfaces, involute surfaces.
