Abstract

The utility model relates to a toothlet shape side cut V takes AV13's profile of tooth structure, glue its characterized in that including top cloth, top: the below is glued on the top has the buffer layer, is equipped with the cotton rope in the buffer layer, is the primer under the buffer layer, and the primer is the cusp. , a profile of tooth height is 9mm, and tooth pitch is 7.2mm, and the tooth depth is 3.5mm, and the profile angle is 43 34/43 ", and tooth root radius R is 1.5mm that toothlet shape side cut V takes AV13. , through a large amount of experiments and in -service use, a toothlet shape side cut V takes AV13's profile of tooth structure advantage is: toothlet shape bending stress is little, occasion that adaptable bend radius is little, the structure of profile angle has increased the shear strength of tooth, satisfies transmission power's requirement, and R's structure avoids the in use tooth root to ftracture in early days, and this profile of tooth structure mainly is fit for AV13's car V area, and the dynamic winding course of this profile of tooth structure is fine, and transmission efficiency is also very high.

Description

A kind of tooth-shape structure of little tooth-shaped edge V tape AV13

Technical field

This utility model relates to a kind of little tooth-shaped edge V tape.Automobile edge V tape AV13 model particularly to little profile of tooth Tooth-shape structure.

Background technology

V belt translation is one of important type of belt drive of machine driving, along with improving constantly and to machine of industrial technology level Tool equipment precise treatment, lightweight, functionalization and personalized requirement, its range of application is increasingly wider, and type of belt drive is the most. As the main element transmission band in V belt translation also by original consumable accessory to functor direction change, its description to Multiformity develops, traditional common infantees V band and conventional belt have developed narrow V belt, wide V band, joined v-belt, edge V tape, many Wedge band, Timing Belt, wire rope core flat rubber belting and chip base flat rubber belting etc..These transmission bands are widely used to automobile, machinery, weaving, household electrical appliances, light The every field such as work, agricultural machinery, plays the most important effect in national economy and people's daily life.

Along with transmission band variety diversity, the improving constantly of serviceability standard, China's transmission band is to produce rope V belt It is main representative with edge V tape, Timing Belt and the big series of polywedge bet two.Edge V tape, polywedge bet and Timing Belt were to send out in recent years Open up transmission band kind faster.At present, edge V tape can be divided into common edge V tape and tooth-shaped edge V tape two kinds, common edge V tape For anodontia flat rubber belting, although flat rubber belting flexible, speed ratio is big；But, its bending stress is big, is generally suitable for the slow-speed of revolution and bending The bigger operating mode of radius, existing structure existence deformation is relatively big, endurance life is poor, easy break-down, the problems such as service life is short, and tooth Shape V carries that it is flexible, bending stress is little, rapid heat dissipation, can use, such as automotive V-belt in the operating mode that high rotating speed and bending radius are less Deng.

Utility model content

This utility model is for solving defect in present stage edge V tape structure, it is provided that one dynamically circumnutates, and transmission efficiency is high The tooth-shape structure of little tooth-shaped edge V tape.

The purpose of this utility model is achieved in that the tooth-shape structure of a kind of little tooth-shaped edge V tape AV13, including top cloth (2), pushing up glue (3), have cushion (4) in lower section, top glue (3), be provided with cotton rope (5) in cushion (4), cushion is primer under (4) (6), primer (6) is in dentation.Described, the construction features of the profile of tooth of a kind of little tooth-shaped edge V tape AV13 is as follows.

Described, the total height of tooth-shaped edge V band structure is 9mm, and pitch of teeth is 7.2mm, and tooth depth is 3.5mm.We are it It is designed as little profile of tooth.A little bit smaller bending stress of tooth is the most a little bit smaller, is i.e. suitable for the occasion that bending radius is little.

Described, profile angle is 43 ° 34 ' 43 ", the structure of profile angle adds the shear strength of tooth, can meet transmission power Requirement.

Described, to concentrate for stress when improve bending, root R is 1.5mm, and in use tooth root can be avoided to open in early days Split.

Described, the R of tooth top is 1.75mm, mainly considers the mold filling character of the course of processing, and the area of tooth is a little big, and V band passes Dynamic side frictional drive strengthens, and the efficiency of the biggest transmission of area is the highest.

The tooth-shape structure benefit effect of a kind of little tooth-shaped edge V tape AV13 of this utility model is: owing to using said structure Design, its bending stress of cogged V-belt is little, dynamically circumnutate very well, rapid heat dissipation, life-span long, and transmission efficiency is the highest, can expire The requirement of foot transmission power；In use tooth root early-age crack can be avoided；Can make in the operating mode that high rotating speed and bending radius are less With, this tooth-shape structure is mainly suitable for the automotive V-belt of AV13.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.

Embodiment 1: as in figure 2 it is shown, this utility model overall structure includes pushing up cloth (2), top glue (3), top glue (3) is at top cloth (2) lower section, connects with top cloth (2), and there is cushion (4) lower section, top glue (3), is provided with cotton rope (5), under cushion in cushion (4) Being primer (6), primer (6) is in dentation.It is monolithically fabricated the structure of the profile of tooth of little tooth-shaped edge V tape AV13.

Embodiment 2: as it is shown in figure 1, the total height of the tooth-shaped edge V band structure of this model is 9mm, pitch of teeth is 7.2mm, Tooth depth is 3.5mm；We are designed as little profile of tooth it, and a little bit smaller bending stress of tooth is the most a little bit smaller, are i.e. suitable for bending radius little Occasion；Profile angle is 43 ° 34 ' 43 ".The design of profile angle adds the shear strength of tooth, can meet the requirement of transmission power； Root R is that the structure of 1.5mm, R stress when improve bending is concentrated, and can avoid in use tooth root early-age crack；The R of tooth top For 1.75mm, mainly considering the mold filling character of the course of processing, the area of tooth is a little big, and V V belt translation side frictional drive strengthens, face The efficiency of the biggest long-pending transmission is the highest.

The tooth-shape structure benefit effect of a kind of little tooth-shaped edge V tape AV13 of this utility model is: owing to using said structure Design, its bending stress of cogged V-belt is little, dynamically circumnutate very well, rapid heat dissipation, life-span long, and transmission efficiency is the highest, can expire The requirement of foot transmission power；In use tooth root early-age crack can be avoided；Can make in the operating mode that high rotating speed and bending radius are less With, this tooth-shape structure is mainly suitable for the automotive V-belt of AV13.
