Definitions
- An object of the present invention is therefore to produce a device that allows the aforesaid drawbacks to be overcome, a particular object is to produce a door opening or gate opening device of small dimensions. Another object of the present invention is to produce a door opening or gate opening device which allows the use of a less powerful motor.
- this gate opening device comprises a first drive shaft 1 adapted to be connected to a motor (not represented for simplicity), a first worm 2 fitted to -or however coaxially mounted on- said first drive shaft 1, a second drive shaft 3 adapted to receive motion from said first drive shaft 1, a first toothed wheel 4 fitted to -or however coaxially mounted on- said second drive shaft 3 and meshed with the first worm 2 to receive motion therefrom, a second worm 5 located on the second drive shaft 3, a third drive shaft 6 connected to a gate opening arm 7, a second toothed wheel 8 fitted to -or however coaxially mounted on- said third drive shaft 6 and meshed with the second worm 5 to receive motion therefrom.
- the second drive shaft 3 is side by side with a fourth drive shaft 9, adapted to receive motion from the first drive shaft 1 and to transmit it to the third drive shaft 6.
- the rotation axes of the two shafts 3, 9 are substantially parallel one with another.
- the second and the fourth drive shaft 3 and 9 are preferably identical, as preferably are the first and the third toothed wheel 4 and 10 and the second and third worm 5 and 11. More generally, the transmission ratio between the first worm 2 and the first toothed wheel 4 is preferably equal to the transmission ratio between the first worm 2 and the fourth toothed wheel 10 and, still preferably, the transmission ratio between the second worm 5 and the second toothed wheel 8 is equal to the transmission ratio between the third worm 11 and the second toothed wheel 8. To reduce noise and improve efficiency, the teeth of the first and of the third toothed wheel meshed on the first worm 2 are inclined. The transmission ratio between the first worm 2 and said first and third toothed wheels 4 and 10 is 27:1. The transmission ratio between said second and third worms 5 and 11 and said second toothed wheel 8 is 27:1. The overall transmission ratio is 729:1.
- the second 3 and fourth drive shaft 9 are mounted on the bearings 13 so as to be able to slide axially back and forth (arrows F) as much as to adapt itself to the manufacture inaccuracies of the first 4 and/or the second 9 and/or the third toothed wheel 10 and/or the first 2 and/or the second 5 and/or the third worm 11, allowing the second 3 and fourth drive shaft 9 to remain simultaneously meshed with the second toothed wheel 8 during operation.
- Approximately the second 3 and fourth drive shaft 9 can slide axially by at least one fourth of the pitch of the second toothed wheel 8, and more preferably they can slide by at least half pitch. However preferably the axial sliding of the second 3 and fourth drive shaft 9 is equal to or smaller than the pitch of the second toothed wheel 8.
- worms allow motion to be transmitted in one direction, but not in the opposite direction.
- the motor can therefore move the gate, but pressure on the gate cannot move the motor and the device according to the invention.
- the toothed wheel 8 uses two 90° sectors of a circle.
- the device receives motion from an electric motor that rotates the first drive shaft 1, on which the first worm 2 is located.
- the motion is transmitted to the first and to the third toothed wheel 4 and 10 with a transmission ratio of 27:1.
- Said toothed wheels rotate the respective drive shafts 3 and 9 with the respective worms 5 and 11, which transmit motion to second toothed wheel 8 which, fitted to the third drive shaft 6, moves the gate opening arm 7.
