Abstract
The utility model provides a miniature V-belt with an annular belt body and a trapezoid section. The miniature V-belt comprises, from outside to inside, a canvas outer layer, a chloroprene rubber layer, a polyester fiber layer, a chloroprene rubber toothed layer, and an elastic nylon cloth layer. Each tooth on the chloroprene rubber toothed layer is in the shape of the letter V and is characterized in that the knuckle radius of the tooth root part is 0.40mm, the included angle of straight lines on the two sides of the waist part is 34 degrees, the knuckle radius of the tooth top is 0.65mm, and the tooth height is 1.71mm. The V-belt is characterized in that the width is 6+/-0.40mm, the thickness is 4+/0.30mm, the sectional included angle is 40 degrees, the pitch of tooth surfaces is 2.6mm, and the number of the V-shaped teeth is 126. The miniature V-belt has improved high temperature resistance and dimensional stability. Through the improvement of the tooth shape, the noise generated during use of the miniature V-shaped is eliminated, the service lifetime of the miniature V-belt is prolongs, the working environment is improved, the efficiency is improved, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of miniature V band.
Background technique
V band is meant that section is the general designation of trapezoidal annular driving band, compares with flat transmission belt, has advantage is installed easily, floor space is little, transmission efficiency is high and noise is little etc., in whole transmission field, occupies critical role.Can be divided into classical V-belt, narrow V belt, wide V band, poly Vbelt etc. by its sectional shape and size; Can be divided into infantees formula V band and merit limit formula V band by the belt body structure; Can be divided into cord core V belt and rope core v belt by the belt carcass structure.Be mainly used in the power transmission of motor and oil-engine driven machinery.
At present, polyurethane when producing miniature V band material commonly used, but this material resistance to high temperature is not enough; And current miniature V mark cun stability is not high, therefore when running up, occur skidding easily when machine, so that the belt wheel intensification is too fast; Cause phenomenons such as chapping, aging appears in belt; Influence working life, improve the enterprise production cost, reduced manufacturing efficiency.And the miniature V band that traditional chloroprene rubber material is produced because its bending properties is lower, therefore noise usually occurs when low cruise, influences working environment.
The model utility content
The utility model provides a kind of miniature V band, and the resistance to high temperature that can well solve traditional product is not enough, and working life is short, and low cruise produces problems such as noise.
For realizing above-mentioned purpose, adopt following technological scheme:
A kind of miniature V band, belt body ringwise, section is trapezoidal, the V band structure is followed successively by canvas skin, neoprene layer, layer of polyester fiber, neoprene band tooth layer and stretchy nylon layer of cloth from outside to inside.
Further improve as the utility model, the tooth on the said neoprene band tooth layer is the V-arrangement tooth.
Further improve as the utility model, the tooth root portion knuckle radius of said V-arrangement tooth is 0.40mm, and waist both sides included angle of straight line is 34 °, and the top knuckle radius is 0.65mm, and tooth depth is 1.71mm.
As the utility model improvement further, the width of said V band is 6 ± 0.40mm, and thickness is 4 ± 0.30mm, and the cross section angle is 40 °, and flank of tooth pitch is 2.6mm, and the V-type tooth number of teeth is 126.
The utility model improves through the material to miniature V band; Improved the resistance to high temperature and the dimensional stability of V band,, effectively eliminated miniature V band and the noise phenomenon in use occurred simultaneously through improvement to profile of tooth; The size of improving belt has prolonged the working life of belt; Improve working environment, improved efficient, reduced cost of production.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model cross sectional representation;
Fig. 2 is the utility model lateral section partial view.
Among the figure:
1, canvas is outer; 2, neoprene layer; 3, layer of polyester fiber; 4, neoprene band tooth layer; 5, stretchy nylon layer of cloth.
Embodiment
Shown in Fig. 1 to 2, provided a specific embodiment of the utility model, among the figure; The V band is followed successively by canvas skin, neoprene layer 2, layer of polyester fiber 3, neoprene band tooth layer 4 and stretchy nylon layer of cloth 5 from outside to inside, and wherein, the tooth on the neoprene band tooth layer 4 is the V-arrangement tooth; Its tooth root portion knuckle radius is 0.40mm; Waist both sides included angle of straight line is 34 °, and the top knuckle radius is 0.65mm, and tooth depth is 1.71mm.The width of this miniature V band is 6 ± 0.40mm, and thickness is 4 ± 0.30mm, and the cross section angle is 40 °, and flank of tooth pitch is 2.6mm, and the V-type tooth number of teeth is 126.
The utility model improves through the material to miniature V band; Improved the resistance to high temperature and the dimensional stability of V band,, effectively eliminated miniature V band and the noise phenomenon in use occurred simultaneously through improvement to profile of tooth; The size of improving belt has prolonged the working life of belt; Improve working environment, improved efficient, reduced cost of production.
