Abstract
The invention discloses a special gear for sliding door and window. The special gear comprises a circular gear body, and engaging teeth which are uniformly arranged at the peripheral edge of the circular gear body, and is characterized in that the tooth profile of the gear is an involute, the pressure angle is 25-35 degrees, the tip clearance coefficient is 0.001-0.2, the modification coefficient ranges from -0.5 to -0.2, the addendum coefficient is 0.4-0.7 and the tooth height is 2mm-5mm. According to the special gear, a traditional mechanical gear design manner is changed and a traditional gear computational formula is released to obtain an involute gear with the large pressure angle, large modification coefficient and ultra-short-gear involute; the gear strength can be improved without extra heat treatment and the gear can be effectively prevented from being broken. In actual application, when the two gears are engaged, the tolerance gap between the involute and the fitting part of the gears is small and a side clearance is basically not formed.
Description
Technical field
The present invention relates to casement window gear-box, particularly relate to a kind of horizontally-opening windows and doors dedicated gear.
Background technique
Gear is a kind of very common mechanical parts, but the gear that architectural hardware uses and all kinds of driving gears that machinery industry uses have significant difference:
1) gear that architectural hardware uses does not need long-time continual motion, and each type gear that machinery industry uses needs long-time or continual motion in 24 hours mostly.
2) gear of all kinds of prolonged exercises of machinery industry use, takes bath lubrication mode mostly, and the gear that architectural hardware uses does not have bath lubrication condition, does not also have this necessary.
3) each type gear General Spatial size restrictions of machinery industry use is less, architectural hardware because of the relation of section bar more to size restrictions, running length should be met, less physical dimension again, and want proof strength, Seeking Truth involute gear again, design difficulty is huge, if the so-called gear of other form should should be regarded as a different matter.
4) machinery industry use each type gear and gear, have diastema (sideshake) between tooth bar.The gear that architectural hardware uses and gear, between tooth bar because of spacious momentum reason, do not allowed diastema (sideshake).
5) material that each type gear of machinery industry use is selective is numerous, and improves intensity by multiple heat treatment mode, and the gear that architectural hardware uses only has zinc alloy, stainless steel bi-material selective, and cannot improve intensity by heat treatment.
Based on above-mentioned 5 reasons, architectural hardware is had higher requirement to used gear, the design people is through for many years to architectural hardware, and the gear-driven Design and Analysis such as shift fork handle, driver sums up a set of practical, is suitable for the gear of architectural hardware industry.
Summary of the invention
The object of the present invention is to provide a kind of architectural hardware general without bottom clearance, without sideshake, large pressure angle, profile modified coefficient, ultrashort tooth involute gear.
For reaching above object, the present invention adopts following technological scheme.
A kind of horizontally-opening windows and doors dedicated gear, comprises the gear of circle and evenly arranges the engaging tooth on gear week edge, it is characterized in that, the flank profil of described gear is involute, pressure angle is 25 ° ~ 35 °, and tip clearance coefficient is 0.001 ~ 0.2, and modification coefficient is-0.5 ~-0.2.
Further illustrating as such scheme, the addendum coefficient of described dedicated gear is 0.4 ~ 0.7.
Further illustrating as such scheme, the tooth depth of described dedicated gear is 2-5mm.
A kind of horizontally-opening windows and doors dedicated gear provided by the invention changes traditional mechanical gear design, free from traditional Gear calculation formula, obtain a kind of large pressure angle, profile modified coefficient, ultrashort tooth involute gear, the strength of gear teeth can be improved without the need to extra heat treatment, effectively avoid fractureing of gear, be particularly suitable for architectural hardware field and use.Successfully fill up the blank that architectural hardware industry does not have complete Series Gear.Promote the technological progress of industry, also improve architectural hardware technology content.For architectural hardware will determine the typical structure of all kinds of driving mechanism from now on, and gear, tooth bar gradate as standard piece lays a solid foundation, and a design of gears difficult problem is readily solved.
