TD Series Part Number Examples
Part numbers for the Dorris TD Series identify motor horsepower, final drive rpm, shaft size, and customer supplied products (i.e. motors & sheaves). 3 o’clock assembly assumed.
107TD3-100-2 107TD series drive for 3 HP, with sheaves to produce a
100 rpm
output speed, using a 2" dia. drive shaft.
Dorris to supply motor and v-belt drive.
107TD3C100-2 107TD series drive for 3 HP, with sheaves to produce a
100 rpm
output speed, using a 2" dia. drive shaft.
Customer to supply motor. Dorris to supply v-belt drive.
107TD3C100C2 107TD series drive for 3 HP, with sheaves to produce a
100 rpm
output speed, using a 2" dia. drive shaft.
Customer to supply both motor and v-belt drive.
Belt Guard Description
Custom belt guards designed for TD Series.
16 gage carbon steel power coated safety yellow with hinged door for easy access.
 
Dorris Supplied V-Belt Selection Criteria
Loading: The minimum rated capacity of a v-belt drive shall be based upon a nominal 1.5 service factor using the rated motor power when used with a gear drive with a service factor of 1.25 – 1.5 or AGMA Class II service. The minimum service factor should be raised to match that of the gear drive when higher gear drive service factors are required.
Sheave type: Only sheaves with tapered bushings for ease of assembly/disassembly and with a minimum of 2 grooves shall be used. Bored to size and single groove sheaves will not be allowed.
Belt type: V-belt cross sections may be either an Ultra-V (3V, 5V, or 8V) or classical (B, C or D only) design. Selection shall take into consideration heat dissipation and be of a cog or wrapped design.
Reduction: Speed reduction with the belt drive shall not exceed a maximum of 2.3/1 for final drive speeds greater than 20 rpm. This will act to prevent excessive belt wear due to low wrap angles.
