Q:Pitch apex to crownDoes that mean the distance between the cone and the cone of the bevel gear to the small end plane of the gear? Or the large section?Is that the crown distance?Is there a requirement for this distance?I use geartrax to design bevel gears. Given the number of module teeth, this distance can not be changed. Is this distance standard?Ask an expert for guidanceBest to ask the national standard, I am not a mechanical industry background, thank you

Straight bevel gear design process is very complex detailed process of a non mechanical industry is difficult, please refer toMechanical design manual Third Volume 23 [gear transmission machinery industry press old version]All relevant drawings of the drawings are endorsed in English. I believe it will help you.

Q:In bevel gear drive, should bevel gears be placed at high or low speed? Why?

Bevel gears should be placed at high speed in bevel gear driveWhen the driving power is constant, the torque of the high speed stage (shaft) is small,

Q:The drawing is depressing. Can you tell me if the angle of the back cone is 90? Are all straight bevel gears with a back cone angle of 90 degrees?That is, the angle between the line and the large end of the gearThere are small gear end, I see a lot of information on the small end of the side of the gear there is concave in the middle, like the word "concave"But I have this picture on hand. The surface is flat. Is there any problem with the design?

But there is also a direct flat down, as long as it does not affect the gear installation, work, no movement interference, no problem.

Q:The main function of gear drive is

The utility model is characterized in that the utility model can be used between two shafts, not parallel, and can be driven at a certain angle (usually vertical).

Q:Good heroes! Brother recently in the study of bevel gear measurement, all kinds of software must input bevel gear installation distance. I know what the installation distance is, but I don't understand what this has to do with my measurement. The other one is the three-dimensional figure measured by the tooth surface of bevel gear. What do you think? Since the involute cylindrical gears have been measured only, the understanding of bevel gear measurement is almost zero. Thank you all!

This should be related to the design itself. For the automatic generation of bevel gear 3D software, this size is required. It must be greater than the crown pitch, if you just need to generate a three-dimensional model of the bevel gear tooth

Q:What is the difference between bevel gear and spiral gear?

Spiral bevel gear is a kind of stable transmission ratio in stable, low noise transmission transmission parts, have different names in different regions, also called arc tooth bevel gear, bevel gear, spiral bevel gears, bevel gear, spiral bevel gear. The spiral bevel gear with high efficiency, stable transmission ratio, arc overlap coefficient, high carrying capacity, smooth transmission smooth, reliable operation, compact structure, material saving, space saving, abrasion resistance, long service life, low noise. In all kinds of mechanical transmission, the transmission efficiency of spiral bevel gear was the highest in all kinds of transmission especially high power transmission has great economic benefits; the need to transfer the same torque transmission a transmission pair, space, belt, chain drive than the space required for small size; spiral bevel gear transmission ratio of permanent stability often, stable transmission ratio is a basic requirement for transmission of the transmission properties of the various types of machinery and equipment; spiral bevel gear reliable work, long service life.

Q:Why can't the tooth width of straight bevel gear be too big?

Then the tooth which is equivalent to 2 modules, so the gear width on stress improvement is not big. So, generally choose teeth width is not greater than the cone bus 1/3.

Q:The big end of the bevel gear to which part?

Bevel gear commonly two contraction form, one is tooth thickness contraction, one is double contraction, double contraction most. As the name suggests is the ends of bevel gears of different thickness, different tooth height, the small end of a mean cone diameter and small diameter at both ends, at the same time, the teeth at both ends are of different sizes, large diameter of a tooth is also big, big, and small end

Q:What material is the straight bevel gear made of?

The main materials of straight bevel gear include: 1, taper angle 2, modulus (standard) 3, tooth crown circle diameter 4, tooth thickness 5, inner hole diameter 6, keyway.

Q:How do we calculate the cone angle of straight bevel gears?

2, when the angle is less than 90 degrees (i.e. two into acute angle)Sub cone angle Delta 1=arctan[sin sigma / (U+cos sigma)]
