Abstract
A technology for modifying the profile of involute gear in order to reduce the engaging noise and vibration features that when an involute gear is made up, its involute profile is modified to have a convex part, so its involute curve is more convex than ordinary one. In addition, the profile is further modified in tooth direction to form a convex curve in tooth direction.
Description
Technical field:
The present invention relates to a kind of correction method of involute gear, belong to the gear machining technology field.
Background technology:
Involute cylindrical gear of the prior art is the most widely used fundamental parts of mechanical transmissioning technology, is widely used in fields such as automobile, lathe, electric power, metallurgy, engineering, boats and ships, Aeronautics and Astronautics.Weigh the quality of gear, generally reliable, the life-span long, vibration noise is low as criterion with working gear.Along with the raising of environmental consciousness, people particularly pay close attention to the vibration and the noise of gear.At present, conventional involute gear is made and is detected according to national accuracy of gear standard design, profile of tooth wherein, tooth alignment error are controlled in the profile of tooth, the teeth directional margin of tolerance of selected accuracy class correspondence, in the margin of tolerance of defined because the shape trend of its profile of tooth tooth curve without limits.In the engagement process of gear pair, because the gear carrying is stressed, produce local elasticity's distortion at the tooth top position, the gear teeth when engaging-in teeth groove often the tooth top wedge angle meet another gear teeth flank of tooth earlier, rather than it is evenly engaging-in to be theoretical involute, will produce bigger impact and gearing noise sound, equally, owing to the axis parallel degree error of gear pair in processing and installation, gear teeth teeth directional also can be partial to a certain side of increment when engagement, the teeth directional contact is inhomogeneous, load when transmission (load) distributes also not at the middle part, monolateral phenomenon occurs and causes local assault, and the force-bearing situation of tooth is also had a negative impact, simultaneously, the vibration and the noise of engagement generation are also bigger.For the influence of the error that reduces the profile of tooth teeth directional, can adopt the way that improves accuracy of gear grade to this generation.But will directly increase manufacture difficulty and manufacturing cost so on the one hand, and also make production efficiency can not get effective raising simultaneously.
Summary of the invention:
The objective of the invention is: provide a kind of under the situation that does not improve the Gear Processing precision, can reduce the correction method of the involute gear of gear meshing noise and vibration effectively, to overcome the deficiencies in the prior art.
The present invention is achieved in that it comprises employing involute gear processing method processing involute gear, when the processing involute gear, on the involute profile of involute gear, its profile of tooth is carried out the cydariform correction of the flank shape, involute gear after making it by correction of the flank shape is compared with the involute profile of theoretical involute gear, involute profile curve after its correction of the flank shape is cydariform, and ask in the facewidth side of its involute gear its profile of tooth is carried out axial modification, the teeth directional of the involute gear after making it by correction of the flank shape is cydariform curve small in ends broad in the middle, thereby obtains involute gears.
Owing to adopted technique scheme, the present invention has carried out the correction of the flank shape of profile of tooth, teeth directional to existing involute gear, resulting involute gears is compared with existing involute gear, the present invention has under the situation that does not improve the Gear Processing precision, just can reduce the advantage of gear meshing noise and vibration effectively, in addition, the present invention also has can reduce difficulty of processing, improve the advantage of product percent of pass, this brings bigger facility for the batch process of gear.
Description of drawings:
Accompanying drawing 1 is the tooth-shape structure schematic diagram of the involute gears that adopts the present invention and process.
In accompanying drawing 1, dotted line is the tooth profile shape of standard involute gear, solid line is the tooth profile shape through resulting involute gears after the correction of the flank shape, the contact zone signal when the oval shadow region in the accompanying drawing 1 is involute gears engagement after the correction of the flank shape.
The specific embodiment:
Embodiments of the invention: process involute gear by traditional involute gear processing method earlier, on the involute profile of involute gear, its profile of tooth is carried out the cydariform correction of the flank shape then, involute gear after making it by correction of the flank shape is compared with the involute profile of theoretical involute gear, involute profile curve after its correction of the flank shape is cydariform, and on the facewidth direction of its involute gear, its profile of tooth is carried out axial modification, the teeth directional of the involute gear after making it by correction of the flank shape is cydariform curve small in ends broad in the middle, thereby obtains involute gears.
Gear modification of the present invention can directly roll inserts the processing acquisition, also can by the gear shaver correction of the flank shape, realize correction of the flank shape through shaving with gear after rolling slotting processing, also can be by roll flute correction of the flank shape realization.
The correction of the flank shape of rolling cut processing: according to the requirement of tooth-formation of gear modification curve, the profile of tooth of corresponding hobboing cutter or pinion cutter is carried out " concave " correction of the flank shape, can obtain the correction of the flank shape of form of gear tooth direction, in addition, can be by the numerical control control technology, making when rolling cut (or slotting) makes hobboing cutter (or pinion cutter) mass motion track realize axial modification with the trend that the axis of gear becomes the axial modification curve to require along carrying out the data adjustment in the process of advancing of teeth directional.
Modification shaving: for the gear that needs the equal correction of the flank shape of profile of tooth teeth directional, reply gear shaver itself carries out corresponding profile of tooth, axial modification during with modification shaving, carry out plunge shaving,, can just can realize by the swing of gear shaving machine workbench if only need axial modification.
Roll flute correction of the flank shape: the gear that adopts roll flute to carry out correction of the flank shape, the profile of tooth of emery wheel can be accomplished " concave ", thereby obtain the correction of the flank shape of profile of tooth direction, can utilize simultaneously Numeric Control Technology to make the roll flute emery wheel in the trend that becomes the modification curve of teeth directional to require along the movement locus in the teeth directional process with the axis of gear and adjust the realization axial modification.
Claims (1)
1, a kind of correction method of involute gear, it comprises adopts involute gear processing method processing involute gear, it is characterized in that: when the processing involute gear, it carries out the cydariform correction of the flank shape to its profile of tooth on the involute profile of involute gear, involute gear after making it by correction of the flank shape is compared with the involute profile of theoretical involute gear, involute profile curve after its correction of the flank shape is cydariform, and on the facewidth direction of its involute gear, its profile of tooth is carried out axial modification, the teeth directional of the involute gear after making it by correction of the flank shape is cydariform curve small in ends broad in the middle, thereby obtains involute gears.
