Description

A kind of light-duty group of infantees V band

Technical field

The utility model relates to a kind of joined v-belts, more particularly, to a kind of light-duty group of infantees V band.

Background technique

There are two types of traditional grouped belts: the common infantees V band of connection group, the narrow infantees V band of connection group.Its articulamentum is certain by having The cord of intensity and sufficiently resilient rubber composition, it is unified into each single V band for entirety, can make the nonuniformity of single V band Vibration offsets each other and reduces to minimum.Adjacent two V band upper inner respectively has one section of vertical plane, makes articulamentum and belt wheel outer circle table There are enough spaces in face, can avoid articulamentum and belt wheel and friction occurs and since belt wheel outer circle is irregularly withstood or torn and connect Layer, and sundries can be accommodated.Grouped belt is vulcanized with identical material one-pass molding, and each V strip length is consistent, good integrity, by Power is uniform, runs smoothly, and bearing capacity is high, and the service life is long, is suitable for high-power transmission.

But raising, reliability raising for being required with the increase of harvester horsepower, compact type etc., connection group classical V-belt, Joined v-belt and structure, service life, transmission power can not meet the transmission demand of high-end harvester again.Be mainly reflected in as Lower two o'clock:

1, connection group classical V-belt band body is too thick, and high-end high-performance harvester, especially rice harvester, in order to mitigate machine Body weight, pulley structure design comparison is compact, and too thick connection group classical V-belt is not suitable for and such belt wheel design requirement；The narrow V of connection group Tape thickness, width are not suitable for the belt wheel design requirement of above-mentioned type.

2, tensile strength, cotton rope adhesive strength, the context layer pull-off intensity of connection group classical V-belt and joined v-belt all compare Low, reference load elongation is relatively high, and fatigue life is shorter；It is unable to satisfy the power transmission of high-end high-performance harvester at all.

Utility model content

The purpose of this utility model is to provide a kind of light-duty group of infantees V bands, are deposited with solving joined v-belt in the prior art The above problem.

For this purpose, the utility model uses following technical scheme:

A kind of light-duty group of infantees V band comprising context layer and at least two single V bands, all single V bands pass through top Context layer be connected as one, the single V band includes face glue, primer, core rope and outsourcing layer of cloth, and the outsourcing layer of cloth is coated on Except face glue and primer, the core rope is set between the face glue and the primer, wherein the bottom surface of the context layer is arranged Have one layer of upper primer layer, the single V band is set to the bottom surface of the upper primer layer, between the core rope and the face glue and One layer of buffering adhesive is provided between the core rope and the primer.

Particularly, it is equipped with two layers of Wide-angle cloth through dipping process between the bottom of the primer and outsourcing layer of cloth, improves Tensile capacity and wearability with body, have extended the service life.

Particularly, two layers of Wide-angle cloth intersects 60 ° of arrangements, and longitude and latitude is strong with enhancing band body entirety tension at 60 ° of angles Degree.

Particularly, the thickness of the upper primer layer is no more than 0.5 ㎜.

The beneficial effects of the utility model are that the light-duty group of infantees V band is not increasing band body compared with prior art Under the premise of thickness, the resistance to plucking for improving the tensile strength with body, cotton rope adhesive strength and context layer takes off intensity, fatigue durability It can good, long service life.
