Abstract
A belt transmission structure is used for solving the problems of a multi-wedge belt and a synchronous belt. The belt transmission structure is formed by a transmission belt and a belt wheel, and is characterized in that transverse synchronous teeth are arranged in the middle of the inner surface of the transmission belt; two sides of the transverse synchronous teeth are provided with longitudinal multi-wedge teeth; a tooth groove meshed with the transverse synchronous teeth in a matched mode is arranged in the middle of the belt wheel; and two sides of the tooth groove are provided with wedge-shaped grooves matched with the longitudinal multi-wedge teeth along the circumference of the belt wheel. The belt transmission structure has the advantages of the multi-wedge belt and the synchronous belt at the same time. During a transmission process, the transverse synchronous teeth on the transmission belt and the tooth groove in the belt wheel carry out meshing transmission to achieve accurate transmission of power; the longitudinal multi-wedge teeth on the transmission belt and the wedge-shaped grooves of the belt wheel carry out friction transmission to achieve high-power transmission. The design enables the shortcomings of the multi-wedge belt and the synchronous belt to be relatively complemented, the advantages of the multi-wedge belt and the synchronous belt coexist, and the high-power transmission and the accurate transmission of the power can be achieved at the same time.
Description
Technical field
The utility model relates to a kind of band drive mechanism, particularly has high-power transmission and can guarantee the band drive mechanism of accurate transmission of power.
Background technique
, stable drive simple with drive mechanism, can cushion absorbing, can be between large distance between shafts and multiaxis transferring power, and it is cheap, it is easy need not lubricate, safeguard, thereby is commonly used in automotive engineering.Transmission of power such as annexes such as the cooling fan of engine system, water pump, compressor, power assistance pump for steering, timing mechanisms is all used the band transmission.At present the conventional belt type of belt drive is a lot, and such as poly Vbelt, Timing Belt, flat rubber belting, circular band, V band etc., dissimilar have separately pluses and minuses with transmission.Large such as the poly Vbelt transmission power, higher by 30% than the transmission power of classical V-belt when the space is identical; Compact structure, in identical transmission power situation, transfer unit take up space is less by 25% than classical V-belt, but the transmission accuracy of poly Vbelt can not guarantee.The belt wheel that Timing Belt is provided with the belt band of equidistant profile of tooth by an interior perimeter surface and has a corresponding identical teeth groove is formed, it combine with transmission, chain transmission and advantage, during rotation, by being meshed transferring power with tooth with the teeth groove of wheel, toothed belt transmission has accurately velocity ratio, without slippage, can obtain constant speed ratio, but Timing Belt is not suitable for the transmission relatively high power.
The model utility content
The utility model is used for overcoming the deficiencies in the prior art, and the band drive mechanism that can transmit relatively high power under a kind of condition keeping accurate velocity ratio is provided.
The alleged problem of the utility model realizes with following technical proposals:
A kind of band drive mechanism, it is comprised of driving belt and belt wheel, and specialization is: the internal surface middle part of described driving belt arranges the synchronous cross tooth, is provided with vertical many wedges tooth in the both sides of synchronous cross tooth; Described belt wheel middle part is provided with the teeth groove with the engagement of synchronous cross tooth coupling, and the teeth groove both sides are provided with the wedge slot that mates with vertical many wedges tooth along the belt wheel circumference.
Above-mentioned band drive mechanism, described driving belt skin is gum layer, and the gum layer bottom is cushion rubber layer, is provided with the enhancing cotton rope at cushion rubber layer, and the enhancing cotton rope vertically arranges two-layer along driving belt, and two-layer cotton rope is interspersed.
Above-mentioned band drive mechanism, described synchronous cross tooth arranges a row along the belt wheel circumference, and the synchronous cross tooth is stepped tooth; Described vertical many wedges tooth is four, and they are symmetricly set on synchronous cross tooth both sides.
The utility model improves the structure of driving belt transmission for the deficiency of poly Vbelt and Timing Belt, has designed a kind of band drive mechanism that possesses simultaneously poly Vbelt and Timing Belt advantage.This driving belt middle part with drive mechanism arranges the synchronous cross tooth, and both sides arrange vertical many wedges tooth, and belt wheel is provided with and the teeth groove of synchronous cross tooth engagement and the wedge slot that mates with many wedges tooth.Said structure is when transmission, and the synchronous cross tooth on the driving belt and the teeth groove engagement driving on the belt wheel realize accurate transmission of power; Vertical many wedges tooth on the driving belt and the wedge slot friction driving on the belt wheel realize high-power transmission.Above-mentioned design is complementary with poly Vbelt and Timing Belt shortcoming, the advantage coexistence, and high-power transmission and accurate transmission of power are realized simultaneously.
