A spur gear is a common name for a spur cylindrical gear. We process various specifications and models of spur gears with good product quality and reasonable prices. Positive teeth are a classification of gears, which are divided into planar gear rotation and spatial gear rotation based on the relative position and tooth direction of a pair of gear axes (whether the two sides are parallel); According to the different working conditions of gears, they can be divided into open transmission and closed transmission; According to the shape of the teeth or tooth profile, they are divided into straight teeth, helical teeth, herringbone teeth, or straight teeth, curved teeth. The product is widely used in hardware, molds, mechanical transmission and other occasions.
A spur gear, relative to a helical gear, is used for gear transmission. Its tooth root height is equal to 1.25 modules, and its tooth tip height is equal to 1 module. M3 represents a gear with a modulus of 3, which is an important parameter of the gear and represents the size of the tooth profile. The larger the modulus, the larger the gear tooth profile.
The main differences between spur gears and helical gears are as follows: it can be said that they are not the same type; It can only be one type of product.
1. Due to manufacturing errors, the instantaneous speed of spur gear transmission varies, mainly due to uneven speed changes caused by manufacturing errors at the moment of tooth meshing, resulting in polygonal effects; 2. The teeth of the helical gear are constantly meshing in and out, without any blind spots in meshing, thus ensuring the uniformity of speed and appearing to run very smoothly.
