Description
Affiliated field
The utility model relates to a kind of gearbox, relates in particular to a kind of roller shutter machine gearbox.
Background technique
At present, green house of vegetables is very big at national usage quantity, and each hot house is according to the difference in season, and the straw screen or mat when it is cold on the booth needs roll at sunrise every day, makes vegetables fully absorb sunlight, improves temperature of shed; Put down at sunset, make night insulation in the booth, help vegetable growth, and need sometimes straw screen or mat is rolled a part, regulate temperature of shed.For realizing that the roller shutter machine stops in the arbitrary position of booth, existing roller shutter machine gearbox has designed self-locking device, its principle all is to utilize gravity self-locking, the scheme that has be belt pulley with driving shaft for being threaded, realize self-locking by belt pulley with respect to the rotation of driving shaft, this mode failure rate of machinery is higher, processed complex, and reliability is lower.
Summary of the invention
But the purpose of this utility model provides a kind of novel roller shutter machine gearbox of simple in structure, service-strong self-locking.
For achieving the above object, the technical solution of the utility model is: novel roller shutter machine gearbox comprises deceleration box, driving shaft, output shaft and intermediate propeller shaft by Bearing Installation on casing, under drive gear is installed in deceleration box, be installed with friction plate in the driving shaft one side bearing outside, the friction plate outside is provided with the ratchet that can slide and rotate and be set on the driving shaft, on deceleration box, be provided with the ratchet corresponding with ratchet, being equipped with on the driving shaft in the ratchet outside can be along driving shaft slip and the power input wheel that rotates, the axis hole outer end of described power input wheel is inlaid with the axle sleeve that band is stirred pawl, the height point that axle sleeve is stirred pawl is the arcuation transition with low spot, and the relevant position that driving shaft is stirred pawl corresponding to axle sleeve is installed with reversed column.
Owing to adopt said structure, novel roller shutter machine gearbox comprises deceleration box, driving shaft, output shaft and intermediate propeller shaft by Bearing Installation on casing, under drive gear is installed in deceleration box, be installed with friction plate in the driving shaft one side bearing outside, the friction plate outside is provided with the ratchet that can slide and rotate and be set on the driving shaft, on deceleration box, be provided with the ratchet corresponding with ratchet, being equipped with on the driving shaft in the ratchet outside can be along driving shaft slip and the power input wheel that rotates, the axis hole outer end of described power input wheel is inlaid with the axle sleeve that band is stirred pawl, the height point that axle sleeve is stirred pawl is the arcuation transition with low spot, and the relevant position that driving shaft is stirred pawl corresponding to axle sleeve is installed with reversed column.When the roller shutter machine moves upward, the power input wheel rotation, the reversed column of driving shaft promotes to be with the axle sleeve of stirring pawl to drive power input wheel and compresses to the ratchet direction, make ratchet pressing friction sheet, ratchet rotates with driving shaft, ratchet and pawl arrangement is not worked, and the curtain rolling shaft at output shaft two ends rotates, and makes the work of roller shutter machine; When power input wheel was unpowered, curtain rolling shaft was under action of gravity, and moment moves downward, because detent mechanism withstands ratchet, the stop motion of roller shutter machine realizes the self-locking of roller shutter machine.When the roller shutter machine moves downward, power input wheel rotation, the axle sleeve that power input wheel is stirred pawl by band is stirred driving shaft and is directly rotated, and this moment, ratchet separated with friction plate, and ratchet freely rotates at driving shaft, and ratchet and pawl arrangement is not worked; When power input wheel was unpowered, curtain rolling shaft continued to move downward under action of gravity, and the reversed column of driving shaft promotes to be with the axle sleeve of stirring pawl to drive power input wheel and compresses to the ratchet direction, and detent mechanism withstands ratchet, and the stop motion of roller shutter machine realizes the self-locking of roller shutter machine.This construction machine processing is simple, rate of fault is lower, reliability is higher.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's a structural representation.
Accompanying drawing 2 is schematic representation of the utility model embodiment's axle sleeve.
Embodiment
As accompanying drawing 1, shown in the accompanying drawing 2, novel roller shutter machine gearbox comprises deceleration box 1, driving shaft 2, output shaft and intermediate propeller shaft by Bearing Installation on casing 1, under drive gear is installed in deceleration box, be installed with friction plate 3 in the driving shaft 2 one side bearings outside, friction plate 3 outsides are provided with the ratchet 4 that can slide and rotate and be set on the driving shaft 2, on deceleration box 1, be provided with the ratchet 5 corresponding with ratchet 4, being equipped with on the driving shaft 2 in ratchet 4 outsides can be along driving shaft 2 slips and the power input wheel 6 that rotates, the axis hole outer end of described power input wheel 6 is inlaid with the axle sleeve 7 that band is stirred pawl, the height point that axle sleeve 7 is stirred pawl is the arcuation transition with low spot, and the relevant position that driving shaft 2 is stirred pawl corresponding to axle sleeve 7 is installed with reversed column 8.Described power input wheel 6 is a belt pulley.Driving shaft 2 ends of described power input wheel 6 outer ends are installed with nut 9, to guarantee the reliability of complete machine.
When the roller shutter machine moves upward, the power input wheel rotation, the reversed column of driving shaft promotes to be with the axle sleeve of stirring pawl to drive power input wheel and compresses to the ratchet direction, make ratchet pressing friction sheet, ratchet rotates with driving shaft, ratchet and pawl arrangement is not worked, and the curtain rolling shaft at output shaft two ends rotates, and makes the work of roller shutter machine; When power input wheel was unpowered, curtain rolling shaft was under action of gravity, and moment moves downward, because detent mechanism withstands ratchet, the stop motion of roller shutter machine realizes the self-locking of roller shutter machine.When the roller shutter machine moves downward, power input wheel rotation, the axle sleeve that power input wheel is stirred pawl by band is stirred driving shaft and is directly rotated, and this moment, ratchet separated with friction plate, and ratchet freely rotates at driving shaft, and ratchet and pawl arrangement is not worked; When power input wheel was unpowered, curtain rolling shaft continued to move downward under action of gravity, and the reversed column of driving shaft promotes to be with the axle sleeve of stirring pawl to drive power input wheel and compresses to the ratchet direction, and detent mechanism withstands ratchet, and the stop motion of roller shutter machine realizes the self-locking of roller shutter machine.This construction machine processing is simple, rate of fault is lower, reliability is higher.
