Description/Basics

The spur gears offered are generally machine elements that serve the non-slip transmission of force, movement transmission or movement change. The teeth of the cylinder wheels grip each other during transmission and largely roll over the tooth flanks. The tooth shape of the spur gear is convexly shaped in the shaped tooth system. At the beginning of the intervention, a rolling resistance acts on the tooth flank, which becomes a sliding friction in the course of the rotation.

A combination of gear wheels and rack gears is useful in the construction of rack gear. This allows motor rotary motion or other rotary motion to be converted into linear motion. rack gear boxes are theoretically possible in an endless assembly. Limits here only set the length of the rack gears for the rack gear drive.

Gear wheels with straight gearing are particularly suitable for the construction of gearboxes. The advantage of straight gearing as opposed to helical gears, is the possibility of transmitting a higher torque. It should be noted that with increasing speed within the transmission ratio or reduction, the torque to be transmitted decreases.

When designing spur gear pairs, the ratio of the gear ratio (number of teeth) and the module of the respective gear wheels must be observed.
The backlash is another important factor that must be considered during construction. Reverse play is understood as the result of the play that the change in the direction of rotation of a single gear wheel pair between the teeth. The risk of reverse play can be reduced if either the diameter or the number of teeth of the cogwheel pairing do not deviate too much from one another. If high wear is to be expected due to the pairing of gears, the MISUMI online shop offers gears with a hardened key-type.

For applications with the same rotational direction, it is possible to use an intermediate gear with integrated bearing on a cantilever shaft. The bearing number used can be found under the tab More Information. An overview of tolerances and permissible radial bearing deviations can be found in the following PDF.

In addition to gear wheels, MISUMI also offers suitable rotary shafts for the construction of a transmission. The straight front wheels can be assembled on these and secured with a set screw or machine keys (key with adjusting screw). This PDF provides an overview of the configurable mountings for the shaft rotation and keyway tolerances.
The continuous adjusting of a spur gear can be realized, among other things, by means of a clamping sleeve. The MISUMI online shop offers spur gears with clamping sleeve. Alternatively, we also offer individual keyless bushing that you can customize to your needs.

Frequently Asked Questions (FAQ)

Question:

Can different modules be combined with each other?
Answer:

Since the module describes the division of the teeth along the pitch circle diameter, various modules cannot be combined into one pair of gears.
Question:

What is involute gearing?
Answer:

Evolved gearing is understood to be the convex production of a tooth flank. The sliding friction along the tooth flank can thus be minimized. This also reduces wear and tear.
Question:

What is the pressure angle?
Answer:

The pressure angle is defined as the angle of the highest drive force between two gears. A combination of different pressure angles is not recommended, since increased wear is to be expected.
Question:

Is the position of the keyway to the key-type specified?
Answer:

The keyway has no specified position reference to the tooth base or the head surface of the sprocket.
Question:

What is the reverse clearance?
Answer:

The reverse play arises at the moment of the direction of rotation of a spur gear pairing is changed. It describes the gap between the gear flanks of each tooth in engagement.
