Abstract

Motorized transport roller comprising: a hollow cylindrical body (11) having an idle head (51) on one side and a motor head (20) on the other; a motor (15) arranged inside said roller having a motor shaft (30) protruding from said motor (15); the roller comprising a first element (53) associated with said motor shaft (30); a second element (54) associated with said motor head (20) by means of a transmission shaft (39); a third element (33) intermediate to said first (53) and second (54) element adapted to transfer the motion from said first element (53) to said second element (54); said third element (33) is made of a soft and/or elastic material; and by said motor head (20) rotating said hollow cylindrical body (11).

Claims

1. A motorized transport roller comprising:

a hollow cylindrical body (11) having an idle head (51) on one side and a motor head (52) on the other;

a motor (15) arranged inside said roller having a motor shaft (30) protruding from said motor (15);

characterized by comprising a first element (53) associated with said motor shaft (30);

a second element (54) associated with said motor head (52) by means of a transmission shaft (39);

a third element (33) intermediate to said first (53) and second (54) element suited to positively couple and transfer the motion from said first element (53) to said second element (54);

said third element (33) is made of a soft and/or elastic material; and

by said motor head (52) rotating said hollow cylindrical body (11).

2. The roller according to claim 1 characterized in that said first element (53) is a substantially cylindrical body having, on one side, a hole (34) for receiving said shaft (30) and on the other side comprising at least one pair of pins (35).

3. The roller according to claim 1 characterized in that said second element (54) is a substantially cylindrical body having, on one side, a hole (34) for receiving said shaft (30) and on the other side comprising at least one pair of pins (35).

4. The roller according to claim 1 characterized in that said third element (33) is a substantially cylindrical body having at least one pair of holes (37).

5. The roller according to claim 1 characterized in that said transmission shaft (39) has a polygonal section.

6. The roller according to claim 1 characterized in that said motor head (52) comprises a bushing having a hole (24) suited to receive said transmission shaft (39).

7. The roller according to claim 1 characterized in that said idle head (51) comprises a pin (14) fixed on one side to a frame of a transport system and on the other side is rigidly fixed to said motor (15).

8. The roller according to claim 1 characterized in that said motor head (52) comprises a bushing (20) fixed to said cylindrical body (11);

said transmission shaft (39) is fixed to said bushing (20);

said bushing (20) comprises a bearing (21);

said bearing (21) allows the bushing (20) to rotate around a pin (22);

said pin (22) is fixed to a frame of a transport roller system.

9. The roller according to claim 1 characterized in that said motor head (52) is rigidly fixed to said hollow cylindrical body (11).

10. The roller according to claim 1 characterized in that said first element (53), said second element (54) and said third element (33) have a diameter less than the diameter of said hollow cylindrical body (11).
