TOP DRIVE® HTD belt is an evolution of standard positive drive belts. The tooth shape is the HTD profile according to ISO 13050.
This profile has been used for many years in a wide range of applications and it is well known for its outstanding performances. Power transmission is much higher compared to the classic inch trapezodial profile.
The circular-arc tooth provides superior tooth jump resistance and provides a smooth tooth engagement. The noise level is remarkably reduced if compared to the classic trapezodial belts.
Locking elements consist of one internal and one external tapered rings. They are designed to work in combination with a clamp flange which can be bolted on a hub or shaft depending on application need.
Here are the dimensions of product :
Inner Diameter : refer to numbers writen after "F" in every product name. For example, CAL2F10/13; so, the inner diameter is 10 mm.
Outside Diameter : refer to the last number in every product name. For example, CAL2F10/13; so, the outside diameter is 13 mm.
Our pulleys can be used for application with a speed up to 35m/s. The pulley dimensions are very accurate as they are manufactured only by means of CNC or automatic lathes.
For higher speed is strongly recomended to use steel as material of construction. Our PBT pulleys are satically balanced according to ISO.
The PT pulleys are not balanced, as they do not have a finished bores.
Here are the dimensions of "PBT" SPA with taper bush 3535 :
- Belt type : SPA
- Taperbush : 3535
- Shaft diameter range : 45 - 90 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT1000SPA3 (3535); so, the pitch diameter is 1000 mm
- Outside diameter : you can add the pitch diameter with 5.6 to know the length of outside diameter.
For example, the product is PBT1000SPA3 (3535); so the outside diameter is 1000 + 5.6 = 1005.6 mm
- Groove : refer to the last number in every product name.
TRASCO® couplings are dimensionally manufactured to hub types "A" and "B", the difference being the maximum shaft diameter which hubs can accpet (corresponding respectively to the first and second code number). The long hub execution "L" (allows full coverage of the motor shaft) is available in both "A" and "B" execution.
