Worm gear speed reductions are fairly cheap, compact and quiet, and can achieve upwards of 20:1 reduction in one stage. However they have two drawbacks which have been the subject of no little discussion on the list. One is that they really do not like to be driven from the backside. In fact, most high-reduction worm gears simply will not turn when attempting to rotate the output shaft.

A worm gear reducer is a right angle gear solution that allows the maximum speed reduction in the smallest package. See similar questions...

Many loom companies experiment with features designed to make weaving easier and better. Sometimes traditional methods of weaving can be the best in the long run. You will have to evaluate the features when you look at purchasing a loom. Worm gears have been added recently to some looms. They are an attempt to achieve fine adjustment of tension on the warp. This is a problem for small looms and worm gears might be a nice feature, especially for a shallow loom. See similar questions...

Worm gear reducers are used in low to moderate horsepower applications. They offer low initial cost, high ratios, and high output torque in a small package. They have a much higher tolerance for shock loading then helical gear reducers. Helical reducers are used in higher horsepower applications where long-term operational efficiency is more important than initial cost. See similar questions...

Kayak polo uses specialized boats, paddles, PFDs (life vests) and helmets, both for safety and performance reasons. The club has boats and other gear available for new players to borrow. Please email us before you come to practice so we can arrange gear for you. If you have your own paddle, sprayskirt, and/or PFD, please bring them with you just in case. You can make your whitewater or touring paddle more polo-friendly by covering the edges of the blade with duct tape. See similar questions...

The Noise Reduction function reduces the noise that is generated during long exposures. When shooting night scenes, shutter speeds become slower and noise tends to appear on images. Turning this function on will reduce the amount of noise in the image. See similar questions...

You need to determine what top speed you want to travel on flat ground. You also need to know your wheel diameter and motor shaft speed. easy and flexible way to ascertain gearing is to figure out how fast your vehicle would go if the the motor were hooked up directly to the drive wheel with no gearing whatsoever. Then divide this by the top speed you desire for your PA, and you have your gear ratio. For instance, say my electric motor goes 3000 rpm (no load maximum). See similar questions...

I’m in complete agreement with Chris Smither, who says, “...within limits, gear is more important as a topic of conversation than as a way of making music.” Except I’m not as diplomatic. I think gear is utterly irrelevant. The people who write gear columns at the guitar magazines are idiots. See similar questions...

A worm gear set is said to be self-locking, or irreversible when the gear cannot drive the worm. This condition is obtained, if the lead angle of the worm is less than the friction angle, and as a consequence the efficiency for reversed driving is zero. The friction angle for static conditions will vary with such factors as surface finish and lubrication. Based upon the generally accepted value of static coefficient of friction equal to 0.15, the friction angle would be approximately 8°. See similar questions...

The ratio of a helical or bevel gear set is simply the number of teeth in the larger gear divided by the number of teeth in the smaller gear. For example, a gear set with 36 teeth in the larger gear and 12 teeth in the smaller gear has 3:1 ratio. The ratio of a worm gear set is the ratio of the number of teeth in the gear to the number of threads (starts or leads) on the worm. For example, a worm with two threads and a mating gear with 60 teeth has a ratio of 30:1. See similar questions...

A worm is similar to a virus by its design, and is considered to be a sub-class of a virus. Worms spread from computer to computer, but unlike a virus, it has the ability to travel without any help from a person. A worm takes advantage of file or information transport features on your system, which allows it to travel unaided. See similar questions...

Because of the efficiency of conventional metric and imperial worm gear screw jacks, the duty cycle is intermittent at rated load. At reduced loading, the duty cycle may be increased. The high duty "Sym-metric" screw jacks have higher thermal efficiencies due to their design allowing generally 50% higher duty cycles than conventional style screw jacks.
