Description

Internal tooth gear Technical Field The utility model relates to the technical field of gears, in particular to an internal tooth gear. Background The wheel is a rotating circular machine part with cutting teeth, or in the case of gears or gearwheels with interposed teeth, which mesh with another compatible toothed part to transfer the switching torque and speed, the gear may also be informally called a gear, the gear means may change the speed, torque and direction of the power source, the gears of different sizes produce torque variations through their gear ratios, creating mechanical advantage, the gear and its gear products are important fundamental parts of the mechanical equipment, the main transmission parts of most mechanical plants are gear drives and can therefore be considered as simple machines. In the prior art, if the publication number is CN220980254U, an internal gear is disclosed, through setting up limit structure, the installation or the dismantlement of being convenient for internal gear body and external gear section of thick bamboo are placed in the inside of spacing boss after aiming at the spacing groove with the locating piece of internal gear body both sides, press two stoppers at top, the inside spring of stopper takes place deformation and produces elastic potential energy, afterwards rotate the internal gear body clockwise along the spacing groove until four stoppers arrive spacing hole department respectively, the spring resumes the original state and releases elasticity, the terminal bullet of stopper is to spacing boss outside, stopper and spacing boss joint from this.
