Gia ya Bevel

Gia za bevel ni gia ambapo shoka za shafts mbili zinaingiliana na nyuso zenye kubeba meno ya gia zenyewe zimeundwa sawa. Gia za bevel mara nyingi huwekwa kwenye shafts ambazo zina digrii 90 mbali, lakini zinaweza kubuniwa kufanya kazi kwa pembe zingine pia. Uso wa lami ya gia za bevel ni koni.

Dhana mbili muhimu katika kushughulikia ni uso wa lami na pembe ya lami. Uso wa lami ya gia ni uso wa kufikirika usio na meno ambao ungekuwa na wastani wa vilele na mabonde ya meno ya mtu binafsi. Uso wa lami ya gia ya kawaida ni sura ya silinda. Pembe ya lami ya gia ni pembe kati ya uso wa uso wa lami na mhimili.

Aina zinazojulikana zaidi za gia za bevel zina pembe za lami chini ya digrii 90 na kwa hivyo zina umbo la koni. Aina hii ya gia ya bevel inaitwa nje kwa sababu meno ya gia yanaelekeza nje. Nyuso za lami za gia za bevel za nje zimeunganishwa na shimoni za gia; kilele cha nyuso mbili ziko kwenye sehemu ya makutano ya shoka za shimoni.

Gia za bevel ambazo zina pembe za lami zenye digrii zaidi ya tisini zina meno ambayo yanaelekea ndani na huitwa gia za ndani za bevel.

Bevel gears that have pitch angles of exactly 90 degrees have teeth that point outward parallel with the axis and resemble the points on a crown. That’s why this type of bevel gear is called a crown gear.

Gia za mita ni gia za bevel za kupandana na idadi sawa ya meno na shoka kwenye pembe za kulia.

Skew bevel gia ni zile ambazo gia ya taji inayofanana ina meno ambayo ni sawa na oblique.

An important concept in gearing is the pitch surface. In every pair of meshing gears, each gear has a pitch surface. The pitch surfaces are the surfaces of imaginary smooth (toothless) bodies that would produce the same gearing relationship by frictional contact between their faces as the actual gears do by their tooth-to-tooth contact. They are a sort of “average” surface that one would get by evening out the peaks and valleys of the individual teeth. For an ordinary gear the pitch surface is a cylinder. For a bevel gear the pitch surface is a cone. The pitch cones of meshed bevel gears are coaxial with the gear shafts; and the apexes of the two cones are at the point of intersection of the shaft axes. The pitch angle is the angle between the face of the cone and the axis. The most familiar kinds of bevel gears, such as those in the picture at the beginning of this article, have pitch angles of less than 90 degrees. They are “pointy”. This type of bevel gear is called an external bevel gear because the teeth are facing outwards. It is possible to have a pitch angle greater than ninety degrees, in which case the cone, rather than forming a point, forms a sort of conical cup. The teeth are then facing inwards, and this type of gear is called an internal bevel gear. In the border line case, a pitch angle of exactly 90 degrees, the teeth point straight forward. In this orientation, they resemble the points on a crown, and this type of gear is called a crown bevel gear or crown gear.

Where two axles cross at point and engage by means of a pair of conical gears, the gears themselves are referred to as bevel gears. These gears enable a change in the axes of rotation of the respective shafts, commonly 90°( or at XX degrees as per print) . We can usefour bevel gears in a square to make a differential gearboxes, which can transmit power to two axles spinning at different speeds, such as those on a cornering truck and automobile and trcotrs.
