Description
Technical field
The utility model relates to agricultural machinery technological field, is specifically related to a kind of roller shutter machine speed reducer.
Background technique
At present, roller shutter machine commonly used can not be realized self-locking with speed reducer, can't make the roller shutter machine according to the needs of crop to daylighting intensity, rests on any working position, and perhaps owing to have a power failure suddenly, the roller shutter machine is taken advantage of a situation and descended, and causes danger or damages booth.
Summary of the invention
The purpose of this utility model just provides and a kind ofly can realize self-locking, roller shutter machine speed reducer safe and convenient to use.
To achieve these goals, the technical solution of the utility model is: a kind of roller shutter machine comprises deceleration box and following deceleration box with speed reducer, driving shaft, output shaft and transmission shaft by Bearing Installation on casing, under drive gear is installed in deceleration box, its structural feature is: be installed with friction plate in driving shaft one side bearing outer end, 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 ratchet, ratchet cooperates with ratchet, also has screw thread on the driving shaft of bearing outer end one side, driving wheel is installed on the driving shaft by screw-thread fit, and the outer end of driving shaft is provided with retention device; Output shaft is the two ends outputs, and the output shaft two ends are fixedly connected with flange plate.
The utility model adopts technique scheme, be installed with friction plate in driving shaft one side bearing outer end, 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 ratchet, ratchet cooperates with ratchet, also have screw thread on the driving shaft of bearing outer end one side, driving wheel is installed on the driving shaft by screw-thread fit, and the outer end of driving shaft is provided with retention device; Output shaft is the two ends outputs, and the output shaft two ends are fixedly connected with flange plate.When the roller shutter machine moved upward, the driving wheel rotation was advanced along hand of spiral, make ratchet pressing friction sheet, ratchet rotates with driving shaft, and ratchet and pawl arrangement is not worked, the flange plate at output shaft two ends connects curtain rolling shaft, make the work of roller shutter machine, when driving wheel was unpowered, curtain rolling shaft was under action of gravity, 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 moved downward, the driving wheel rotation retreated along hand of spiral, ratchet and friction plate are separated, and ratchet freely rotates at driving shaft, and ratchet and pawl arrangement is not worked, the flange plate at output shaft two ends connects curtain rolling shaft, makes the work of roller shutter machine, when the driving wheel driving wheel is unpowered, curtain rolling shaft continues to move downward under action of gravity, the driving wheel rotation, advance along hand of spiral, make ratchet pressing friction sheet, because detent mechanism withstands ratchet, the stop motion of roller shutter machine realizes the self-locking of roller shutter machine.Make the roller shutter machine according to the needs of crop, rest on any working position daylighting intensity, and safe and convenient to use.

Fig. 2 shows the schematic representation of ratchet and pawl arrangement among the utility model embodiment;
Embodiment
The utility model comprises deceleration box and following deceleration box, driving shaft 2, output shaft 9 and transmission shaft by Bearing Installation on casing 1, in deceleration box 1, under drive gear is installed, be installed with friction plate 3 in driving shaft 2 one side bearing outer ends, friction plate 3 outsides are provided with the ratchet 5 that can slide and rotate and be set on the driving shaft 2, on deceleration box 1, be provided with ratchet 4, ratchet 4 cooperates with ratchet 5, also has screw thread 8 on the driving shaft 2 of bearing outer end one side, driving wheel 6 is installed on the driving shaft 2 by screw thread 8 cooperations, and the outer end of driving shaft 2 is provided with nut 7; Output shaft 9 is two ends output, and output shaft 9 two ends are fixedly connected with flange plate 10.
When the roller shutter machine moved upward, driving wheel 6 rotations were advanced along screw thread 8 directions, make ratchet 5 pressing friction sheets 3, ratchet 5 rotates with driving shaft 2, and ratchet 5 ratchets 4 mechanisms do not work, the flange plate 10 at output shaft 9 two ends connects curtain rolling shaft, make the work of roller shutter machine, when driving wheel 6 was unpowered, curtain rolling shaft was under action of gravity, moment moves downward, because ratchet 5 withstands in ratchet 4 mechanisms, the stop motion of roller shutter machine realizes the self-locking of roller shutter machine.When the roller shutter machine moves downward, driving wheel 6 rotations, retreat along screw thread 8 directions, ratchet 5 and friction plate 3 are separated, ratchet 5 freely rotates on driving shaft 2, and ratchet 5 ratchets 4 mechanisms do not work, and the flange plate 10 at output shaft 9 two ends connects curtain rolling shaft, make the work of roller shutter machine, when driving wheel 6 was unpowered, curtain rolling shaft continued to move downward under action of gravity, driving wheel 6 rotations, advance along screw thread 8 directions, make ratchet 5 pressing friction sheets 3, because ratchet 5 withstands in ratchet 4 mechanisms, the stop motion of roller shutter machine realizes the self-locking of roller shutter machine.Make the roller shutter machine according to the needs of crop, rest on any working position daylighting intensity, and safe and convenient to use.
