2. Self-Locking Feature of Worm Gear Pair
Self-locking is defined as the inability of worm wheels to drive
the worms. Factors affecting the self-locking feature include the
materials of the worm and worm wheel, lead angle, precision of
manufacture, types of bearings, lubricant, etc. Thus, it is not dependent simply on the lead angle. But, in general, self-locking will
。
occur when the lead angle in a single thread worm is less than 4.
For systems requiring fail-safe prevention of back drive, we recommend other braking mechanisms or one-way clutches.

Selection Hints
Please select the most suitable products by carefully considering the characteristics of items and contents of the product tables. It is
also important to read all applicable “CAUTION” notes shown below before the final selection. Use of catalog numbers when ordering will simplify and expedite the processing of your order.
 The Helixes of Worms and Worm Wheels
1. Caution in Selecting the Mating Gears
Worms and worm wheels have either right-hand or left-hand helix. The
same hand worms and worm wheels comprise sets. However, the
number of threads and whether they use normal module or axial module
system must also be matched. The table below shows available combinations of KHK stock worms and worm wheels.

1. Caution on Performing Secondary Operations
a If you are reboring, it is important to pay special attention to
locating the center in order to avoid runout. (Fig.1) The reference
datum for gear cutting or grinding is the bore. (For worm shafts,
it is ground portion of the shaft.) Therefore, use the bore or shaft
for locating the center. If it is too difficult to do for small bores, the
alternative is to use one spot on the bore and the runout of the
side surface.
Lathe Operation
2. Points of Caution in Assembling
a KHK stock worms and worm wheels are designed such that
when assembled according to the specified Mounting distance with a tolerance of H7 to H8, the backlash shown in the product tables is
obtained. Do not attempt to eliminate backlash by pushing worms
into worm wheels or operate with the worm shifted in the direction along the tooth.
b The figure below shows the datum clamp face of a worm wheel.
When assembling worm gears, be sure that the worm axis is in
the center of the worm wheel face width.

Ring geometry
c Because of the helix of the gear teeth, worms and worm wheels
produce axial thrust forces. The directions of thrust depend on the
hand of the helix and the direction of rotation. This is illustrated below in Fig.2. The bearings must be selected properly to be able to
handle these thrust forces. See the “Gear Forces” section in the
technical reference for more details (Page 107).

If chucking operation using scroll chucks is to
be done, we recommend the use of new or
rebored jaws for improved precision.

b To open up the bore to its maximum, calculate the bore size
so that the tooth strength is weaker than the strength of the
remaining material.
For machining the maximum bore diameter, it should be designed
so that the thickness between hub diameter (or root diameter)
to bore diameter has more strength than the gear strength. As a
guide, the maximum machined bore diameter should be within
60% to 70% of the hub diameter (or root diameter). When the
keyway is processed, it should be 50% to 60%. In the case FC
material is used, it should be lower by 10% or more.
c Since worm wheels are molded products, they may have air
bubbles inside the material. In case you find air bubbles inside
when performing secondary operations, and if the bubbles are
found to be troublesome, please contact your KHK distributor.

d Because large thrust forces act on worms, if they are not secured to the shaft firmly, they tend to shift. Use of step shafts, set
screws, dowel pins, etc., are recommended. Also, check for loosening of bearings due to thrust forces.
3. Verifying the orientation of assembly
How well the worms and worm wheels are assembled has large effects on the friction of the unit. The tooth contact at the time of
assembly must be checked for correctness as shown below. See the “Tooth Contact of a Worm Gear Pair” section in the technical reference for more details (Page 67).
• Verify that the worm axis is perpendicular to the worm
wheel axis.

Description of duplex worm gears
The usual method of adjusting the backlash of a worm gear assembly
Helical
Gears
is to modify the center distance. Once assembled, such adjustment
requires a major rework of the gearbox housing. The use of duplex
worm gears allows the backlash adjustment to be made by axially
shifting the worm. This simplifies greatly the assembly and mainte-

nance operations. Because of the unique characteristics of the product, please take time to study its construction and proper use.

Backlash adjustment mechanism and method of adjustment
The dual-lead worm is formed to give a difference between the right tooth surface and left
tooth surface so that it provides a unique tooth profile in which the tooth thickness varies
The worm gear is also formed in its right and left tooth surface.
When such a worm and worm gear are set up at a constant assembly distance and the
worm is moved in the axial direction, the tooth thickness of the worm in mesh with the
worm gear changes making backlash adjustment possible.

(CAUTION)The amount of change in backlash (△j mm) in relation to the axial movement of the duplex
worm shaft (V mm) can be calculated from the formula below.
Δ j=2V

Moving the worm in the direction of the

The KHK duplex worm is designed so that, for all modules, the backlash reduces by 0.02 mm when the worm is shifted 1 mm.
Application Examples

Adjustment by using Screws *
514
An arrow marking on the outer circumference of the hub of the
KHK duplex worm indicates the direction of assembly as well as
acts as a guide for the backlash adjustment.
When the worm is held with arrow mark pointing right, the tooth
thickness is thinner on the right and thicker on the left. Therefore,
moving the worm to the right causes the thicker teeth to come
into actual engagement with the worm gear, thereby reducing the
backlash. (Fig.2)

Point of caution during assembly
KHK duplex worm gears differs in module between the right and left

Arrow mark indicates the correct orientation of two gears when assembled. As shown, the two arrows must point in the same direction.

2. Verifying the reference position
A V-groove (60°, 0.3 mm deep line) on tip peripheral of the duplex worm tooth marks the reference tooth. The gear set is designated to
have a backlash of nearly zero (±0.045) when the reference tooth is positioned in alignment with the center of rotation of the worm wheel

1. Verifying the orientation of assembly
An arrow indicating the orientation of assembly is stamped on both the duplex worm and worm wheel. When assembling the
worm and worm wheel, check the worm wheel of the arrow mark on the front such that the direction of arrow mark on the worm
coincides with that on the worm wheel. Should the assembly be incorrect, the center distance “a” will become larger than the
normal distance, resulting in difficulty of assembly and improper gear engagement. (Fig.3)

causing problems with the gear mesh. The V max is not a recommended value to use for adjustment when assembling.

b Significant variations in temperature or humidity can cause dimensional changes in plastic gears (MC Nylon gears), for bore
size (H8 when produced), teeth diameter, and backlash.
c The allowable torques shown in the table are the calculated values according to the assumed usage conditions. Please see
regards to MC Nylon gears, other materials are available for plastic gears, including Ultra High
Molecular Weight Polyethylene (UHMW-PE), which has excellent abrasion resistance. Poly Ether Ether
Ketone (PEEK) also has quality properties. A single piece order is acceptable and will be produced as
a custom-made gear. For details on quotations and orders please see page VI.

b Significant variations in temperature or humidity can cause dimensional changes in plastic gears (MC Nylon gears), for bore size (H8 when
produced), teeth diameter, and backlash.
c The allowable torques shown in the table are the calculated values according to the assumed usage conditions. Usage above the value in brackets will exceed the maximum allowable sliding speed, if no lubrication is applied. So, lubrication is required. Please see page 510 for more details.
