Description

The processing method for improving spiral bevel gear interchangeability
Technical field
The present invention relates to a kind of gear machining technology, especially a kind of spiral bevel gear processing method, specifically one The processing method that kind improves spiral bevel gear interchangeability.
Background technology
At present, spiral bevel gear processing method both domestic and external:Typically after flank of tooth finishing, upper spiral bevel gear meshing device Check bevel gear pair contact zone, sideshake and locating distance.Processing in pairs, exchange in pairs, it is impossible to which individually processing is exchanged.When a pair of spirals Wherein one generation problem of bevel gear pair, it is necessary to change spiral bevel gear in pairs, and that problematic part spiral shell can not be individually replaced Revolve bevel gear.Processing and replacement cost are higher.
The content of the invention
The purpose of the present invention is processed and changed for existing helical gear, need to be processed and be changed in pairs, and can not be single The problem of solely changing.A kind of processing method for improving spiral bevel gear interchangeability is invented, must be paired to solve spiral bevel gear The problem of processing and changing in pairs.Spiral bevel gear replacement cost is reduced, improves spiral bevel gear service efficiency.
The technical scheme is that:
A kind of processing method for improving spiral bevel gear interchangeability, it is characterized in that it comprises the following steps:
First, the parameter input computer for the spiral bevel gear that need to be processed is obtained into the theoretical topological diagram deviation of Gear shape process Value;
Secondly, the front and rear conical surface of spiral bevel gear blank is machined using high precision digital control lathe;
3rd, the spiral bevel gear blank Jing Guo Vehicle Processing rough mill tooth with Spiral Bevel machine, controls tooth Face precision;
4th, heat treatment carburizing and quenching, control deformation will be carried out by rough milling the spiral bevel gear of tooth;
5th, the spiral bevel gear through Overheating Treatment is subjected to centering basic circle and reference plane, finishes basic circle and base Quasi- face;
6th,, will again with the hard scraping flank of tooth of Spiral Bevel machine based on finishing basic circle and reference plane Spiral bevel gear after shaving action is placed on inspection flank of tooth topological diagram deviation on metering gear instrument, by actual flank of tooth topological diagram deviation Value, if both differences are more than setting value, adjusts cutting parameter, and use spiral shell again compared with theoretical topological diagram deviation The hard scraping flank of tooth of conical gear milling machine is revolved, until topological diagram deviation is in setting range;
Finally, upper spiral bevel gear meshing device, the value of inspection record contact zone (contact (area) pattern), locating distance and sideshake so as to The spiral bevel gear changed with the need in the margin of tolerance is interchangeable.
The difference range of actual flank of tooth topological diagram deviation and theoretical topological diagram deviation is -13 μm~+7 μm.
The spiral bevel gear processed by above-mentioned requirements has certain interchangeability, is processed using same helical datum bevel gear Spiral bevel gear can exchange completely.
The beneficial effects of the invention are as follows:
The present invention is utilized by controlling spiral bevel gear flank of tooth topological diagram deviation, to ensure spiral bevel gear flank of tooth curved surface Uniformity, so as to ensure the interchangeability of spiral bevel gear.Matching spiral bevel gear, flank of tooth topological diagram in setting range, transverse tooth thickness, The spiral bevel gear of sideshake and locating distance in the margin of tolerance can carry out exchange.The processing of spiral bevel gear can be saved and made Use cost.There is certain reference function to the interchangeability of other complex-curved mating parts.
The present invention realizes spiral bevel gear and exchanges processing, has the advantages of precision is high, efficiency high.
Brief description of the drawings
Fig. 1 is spiral bevel gear structural representation of the present invention.
Fig. 2 is the theoretical topological diagram of the spiral bevel gear flank of tooth of the present invention
Fig. 3 is the actual measurement topological diagram of the spiral bevel gear flank of tooth of the present invention.
Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As Figure 1-3
A kind of processing method for improving spiral bevel gear interchangeability, it comprises the following steps:
First, the parameter input computer for the spiral bevel gear need shown in Fig. 1 processed obtains the theory of Gear shape process Topological diagram, such as Fig. 2;
Secondly, on high precision digital control lathe, the conical surface before and after processing, to ensure the conical surface and rough mill tooth locating distance precision;
3rd, the upper special tooth milling machine of spiral bevel gear rough mills tooth, and flank of tooth topological diagram deviation is checked in gear gauge, Tooth precision is rough milled in control, to ensure the uniformity of allowance for finish;
4th, using Quenching press, using rational charging mode, reduce the deformation of carburizing and quenching workpiece;
5th, centering reference plane and basic circle, finish reference plane and basic circle;
6th, the upper hard scraping flank of tooth of the special tooth milling machine of spiral bevel gear stays refine surplus, and gear gauge checks the flank of tooth Topological diagram deviation, and according to check situation, adjust hard scraping Cutting Parameters, with ensure final flank of tooth topological diagram deviation- In 13 μm~+7 μm(Such as Fig. 3), spiral bevel gear flank of tooth curved surface has uniformity.
Finally, upper spiral bevel gear meshing device checks contact (area) pattern, sideshake and locating distance parameter in case adapted is changed at any time.
Details are as follows:
Due to the particularity of spiral bevel gear wheel construction, it is impossible to as common cylinder gear, using general gear-hobbing machine and Roll flute machines, and has higher interchangeability.Spiral bevel gear need to use corresponding size cutterhead and cutter pad, rough mill tooth and Essence, which is scraped, to be formed.Due to rough milling the difference of gear blank processing dimension, cutterhead size and cutter shim size before tooth, cause spiral bevel gear There is larger difference in the flank of tooth, cause spiral bevel gear to process and use in pairs.The present invention is by improving the spiral bevel gear gear teeth Base precision, control the uniformity of locating distance and transverse tooth thickness;By controlling heat treatment deformation heat treatment and final flank of tooth topological diagram With the uniformity of theoretical topological diagram.So as to ensure the uniformity of spiral bevel gear processing, realize that the interchangeability of spiral bevel gear adds Work.
Aforementioned invention purpose has been effectively achieved by the present invention.
Part that the present invention does not relate to is same as the prior art or can be realized using prior art.
