Description
Technical field
The present invention relates to equipment transmission field, specifically a kind of belt stretcher.
Background technology
Belt transmission be moved using the flexible-belt being stretched on belt wheel or power transmission a kind of machine driving.Skin
V belt translation has that structure is simple, stable drive, can buffer absorbing, can be in the spy such as big distance between axles and many between centers transmission power
Point, and it is cheap, be not required to lubrication, safeguard easily.According to the difference of transmission principle, have by the friction between belt and belt pulley
The Friction Type Belt Drive of power transmission, also has the toothed belt transmission engaging each other transmission by the tooth on belt and belt pulley.
Belt transmission can be relaxed due to flexible-belt plastic deformation after work a period of time, so that initial tension is reduced, be driven energy
Power declines.In order to ensure the transmission capacity of belt it is necessary to re-tensioning.At present, commonly used tensioning mode mainly has deadweight
Tensioning, heavy-hammer-tightening, regular tensioning etc., but the structure exposing is not compact, it is big to take up room, adjustment is inconvenient, Adjustment precision is poor
The problems such as especially prominent.Periodically tensioning needs periodically to carry out, and increased the labor intensity of worker；And tensioning of conducting oneself with dignity, heavy-hammer-tightening
If tensioning is not in time, transmission capacity reduces, and necessarily brings hidden trouble of equipment.This had both caused the absorbability to load variations for the motor
Reduce and Frequent Troubles, affect equipment overall operation rate, and because belt life is short, changing number of times increases, and spare part expense improves.

Nut 6 is respectively positioned on outside diplopore riser 2.The described long locknut 6 adjusting in locating rod 4 is located at outside single hole riser 3.
When concrete operations are implemented, lower margin hole and the ground bolt connection that be provided with tensioning pedestal 1 by seat bottom are so as to consolidate
Fixed firm.Afterwards motor base is arranged on table top, and makes four foundation bolts that motor base is provided be each passed through platform
Four long strip through holes 10 on face, the tapped through hole 12 being provided with tensioning slide block 8 respectively is connected, and tightens foundation bolt and completes to pacify
Dress process.When needing to carry out tensioning operation to motor belt, first motor is had a power failure, after belt pulley stops operating, by
Foundation bolt is unscrewed by spanner, and the degree unscrewed reaches motor under the drive of tensioning slide block 8 and integrally can realize moving.
Measuring belt using meter ruler needs length M of tensioning, adjusts locating rod 4, minor section locating rod 5 and tune to long respectively by spanner
Locknut 6 on section nutted rod 9 carries out outward turning, and wherein long locknut 6 outward turning adjusting in locating rod 4 is more than skin apart from N
Band needs tensioning length M, outwards screws out minor section locating rod 5 apart from N by spanner, by spanner will adjust nutted rod 9 to
Outer back-out, adjusts nutted rod 9 and drives tensioning slide block 8 to slide in chute, drive motor moves integrally tensioning slide block 8 simultaneously, when
When regulation nutted rod 9 outward turning length reaches M, continue outward turning until belt reaches the tensioning degree of needs.If now outward turning is long
Degree needs more than N, above outward turning need to be continued outward turning one by one apart from P apart from N.Need tensioning apart from N more than belt
Length M and continuation outward turning are to increase tensioning degree, increasing tensioning degree one side in order to avoid because of behaviour apart from the purpose of P
During work, motor produces small distance return, does not reach tensioning requirement；On the other hand it is in order to avoid tensioning degree not equipment
Can be relaxed again due to belt plastic deformation after running a period of time, so can reduce tensioning number of times.Work as motor belt
After tensioning reaches use requirement, first pass through spanner screw-in two pieces length regulation locating rod 4 and hold out against motor base side, then distinguish
Screw in two pieces minor section locating rod 5 hold out against motor base opposite side it is ensured that motor position is parallel with original position, then successively to open
Tight pedestal 1 direction screws and adjusts nutted rod 9, the long locknut 6 adjusting in locating rod 4 and minor section locating rod 5 and fasten jail
Gu, finally tighten motor foundation bolt, start motor and confirm that motor belt stable drive, no skidding, noise are low.
The present invention, on the basis of conventional motor is directly connected to installation ground, by arranging tensioning pedestal 1, makes motor straight
Connect and be arranged on tensioning pedestal 1, on tensioning pedestal 1, the supporting minor section locating rod 5 playing position-limiting action that is provided with is determined with growing regulation
Position bar 4, and be used for motor is carried out with the regulation nutted rod 9 of displacement drive.Wherein, two minor section locating rods 5 are used for electricity
Machine base side carry out spacing, two long adjust locating rods 4 be used for motor base opposite side is carried out spacing.By adjusting tensioning
The screw-in of bar 9 and back-out, can flexible controlled motor displacement, realize belt tension.And adjust nutted rod 9, long regulation is determined
It is equipped with locknut 6, locknut 6 can be fixed to regulation nutted rod 9, long regulation after tightening on position bar 4 and minor section locating rod 5
Position bar 4 and minor section locating rod 5 play further position-limiting action.Belt tension regulation is carried out by this device, Adjustment precision is high,
Tensioning degree accurately, decreases tensioning number of times, need not periodically carry out tensioning operation, reduce the labor intensity of operator.And
And adjusting nutted rod 9, the long collective effect adjusting locating rod 4, minor section locating rod 5 and locknut 6 after belt adjustment
Under, belt occurs needing the number of times of tensioning to reduce 3-4 times in identical run time, so within the equal activity duration,
Tensioning number of times reduces, and greatly reduces the hidden trouble of equipment bringing not in time due to tensioning operation, improves belt simultaneously and use the longevity
Life, decreases replacing number of times, and spare part expense reduces.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
