Abstract
The utility model provides a novel double helical tooth synchronous pulley, and belongs to mechanical parts. The novel double helical tooth synchronous pulley comprises a belt wheel base body, gear teeth and tooth grooves, and the gear teeth and the tooth grooves are arranged on the belt wheel base body. The novel double helical tooth synchronous pulley is characterized in that the normal tooth profile of each belt wheel teeth is formed by connecting circular curves. A circle center of a tooth flank circular arc is located on a belt wheel pitch circle. The wheel teeth are divided into laevorotation belt teeth and right-handed belt teeth, and a distance is staggered between the central line of each laevorotation belt tooth and the central line of each right-handed belt tooth, the laevorotation belt tooth and the right-handed belt tooth are adjacent, and the distance is half of a pitch. The novel double helical tooth synchronous pulley can be used in transmission of fields such as an automobile, a light industry, spinning, food packaging, printing machinery, tobacco machinery, office automation equipment, household appliances, medical treatment and public health equipment and a numerically-controlled machine tool. The belt teeth are free from flanges, and conception is clever and novel. Compared with straight tooth synchronous belt drive, obvious improvements can be seen in aspects such as transmission accuracy promotion, noise reduction and bearing capacity improvement, and the novel double helical tooth synchronous pulley can be easily popularized and applied in a large-scale mode.
Description
Technical field:
The utility model belongs to mechanical part, and what be specifically related to is a kind of Novel herring bone tooth synchronous pulley.
Background technique:
Synchronous pulley is industrial transmission device commonly used, is used widely in fields such as automobile, light industry, weaving, food package, printing machinery, tobacco machine, business automation equipment, household electric appliance, health care equipment, numerical control machine tools.Toothed belt transmission relates to belt wheel and Timing Belt, it is the engagement type transmission of a kind of embedding, but, when existing Toothed belt pulley and band engagement driving, due to installation, production problem, band produces on the gear teeth and moves axially, therefore belt wheel needs shelves limit or flange are with the movement of check strap, make pulley structure become complicated, the Timing Belt band touches with the shelves edge joint and produces friction simultaneously, reduces working life and the transmission efficiency of band, and friction also can produce by the certain noise of association, band may at belt shaft to transmission, cause transmission accuracy to reduce simultaneously.
The model utility content:
Based on the plurality of advantages of herringbone tooth toothed belt transmission, the utility model provides a kind of herringbone tooth synchronous pulley of novel tooth form, coordinates transmission with Novel herring bone tooth Timing Belt, has more sliding suitable, the characteristics such as transmission accuracy is high, bearing capacity is strong, noise reduction of transmission engagement.
The technological scheme that its technical problem that solves the utility model adopts is: this Novel herring bone tooth synchronous pulley, comprise the belt wheel matrix, and be located at the band gear teeth on the belt wheel matrix and take turns teeth groove, it is characterized in that: the gear teeth are divided into left-hand teeth and right-hand teeth, and adjacent left-hand teeth center line and the right-hand teeth center line segment distance that staggers, this distance be pitch half.
The normal tooth profile of described teeth groove is comprised of tooth root circular arc, flank circular arc, tooth top transition arc.
The helix angle of described left-hand teeth and right-hand teeth is 20 °～30 °.
The tooth depth of the described gear teeth is 3.5mm.
The center of arc of described flank circular arc is positioned on the nodel line of this belt wheel.
The radius of described tooth root circular arc is 0.85～0.95mm.
The radius of described flank circular arc is 7.8～8.2mm.
Described tooth top transition arc radius is 0.55～0.65 mm.
Effect intentionally of the present utility model is: the normal direction flank curve of the Novel herring bone tooth synchronous pulley gear teeth is the circular curve that the center of circle is positioned at the belt wheel pitch circle, when making with corresponding Novel herring bone tooth Timing Belt engagement driving, it is more sliding suitable when the band tooth embeds the wheel teeth groove, allow the belt wheel teeth groove and with between cog, less sideshake arranged, and the elimination polygon effect, improved transmission accuracy; The herringbone tooth belt wheel has the bootstrap function, can reject the rib of belt wheel; Band gear teeth herringbone Heterogeneous Permutation, than same specification, size straight-tooth synchronous belt pulley transmission noise reduction 10-20 decibel, transmitted power is larger, more compact structure.
