Abstract
Description
- 1. Field of the Invention
- The invention relates to cutter blades for the production of gears and, more particularly, to cutter blades for the face hobbing of parallel depth spiral bevel and hypoid gears.
- 2. Description of the Prior Art
- Spiral bevel and hypoid gear pairs are conventionally produced utilizing either an intermittent index face milling method or a continuous indexing face hobbing method. While most gear set manufacturers currently use the face milling method, the face hobbing process has been recently adopted by some manufacturers, especially those manufacturing such gear sets for vehicular applications. In a face hobbing machine, a circular face hob type rotary cutter carrying a plurality of cutter blades mounted in groups, is utilized, and a workpiece (gear blank) and the cutter continuously rotate in a timed relationship until the entire part is completed. During the cutting process, the workpiece indexes in a rotary manner so that each successive cutter blade groups engaging successive tooth slots as the gear or pinion member is being cut. Advantageously, the face hobbing method produces uniform depth teeth, and parts are produced from the solid in one operation. The face hobbing method also requires fewer production steps and less production time than the face milling method.
- Normally, in an operation separate from, and preceding to, the tooth cutting operation, a topland surface of the gear is machined while processing a ring gear or pinion gear blank before cutting the gear teeth. As well known to those skilled in the art, the additional production step is generally disadvantageous with regard to cost, labor, quality control, and manufacturing flexibility.
- The present invention relates to a gear cutter blade for use with a face hob type cutter for producing teeth of spiral bevel and hypoid gear members by a continuous index, face hobbing process. The gear cutter blade comprises a cutter blade shank adapted to be mounted on a rotatable cutter body, and a cutting member provided at one end of the blade shank. The cutting member includes a tooth side cutting edge having a given axial pressure angle, and a topland cutting edge adjacent the tooth side cutting edge. The topland cutting edge of the cutting member simultaneously forms a topland surface of the tooth of the gear member as a tooth side surface is cut by the tooth side cutting edge of the cutting member.
- Machining the topland surface simultaneously with the cutting the tooth side surface permits to reduce or completely eliminate the need to finish topland surfaces of the ring gears or pinions. Moreover, the elimination of a subsequent manufacturing operation improves the consistency and accuracy of the gear tooth whole depth, and part quality, as well as reduces manufacturing costs. In addition, the gear cutter blade of the present invention allows for greater manufacturing flexibility, as the cutting edge dimensions can be easily modified, and provides an ability to machine near-net forged parts without requiring precision control of the topland area of machining with an interrupted cut during a blanking operation.
- Other objects and advantages of the invention will become apparent from a study of the following specification when viewed in light of the accompanying drawings, wherein:
- FIG. 1 is a plan view of a front face of a gear cutter blade in accordance with the preferred embodiment of the present invention and a portion of a gear member on which the cutter blade is operating;
- FIG. 2 is a partial perspective view of a ring gear;
- FIG. 3 is a view of the cutter blade of FIG. 1 illustrating geometry of a cutting edge thereof in accordance with the present invention;
- FIG. 4 illustrates the arrangement of a workpiece (a ring gear) and a cutter in a face hobbing process used in the present invention;
- FIG. 5 is a plan view of the front face of the gear cutter blade in accordance with the alternative embodiment of the present invention dimensioned to cut an entire topland surface of a gear tooth of the gear member.
- The preferred embodiment of the present invention will now be described with the reference to accompanying drawings.
- Referring to FIGS. 1 and 3, the
reference numeral 10 represents a gear-cutting blade in accordance with the present invention and thereference numeral 12 depicts a portion of aring gear member 12 having a plurality ofgear teeth 14 on which thegear cutting blade 10 is operating during a face hobbing process. Eachgear tooth 14 includesopposite side surfaces 16 and atopland surface 18. The reference numeral A represents a whole depth of thegear teeth 14. Thegear member 12 is also illustrated separately in detail in FIG. 2. - A plurality of the
cutter blades 10 is mounted at a selected radius and depth on a rotatable,circular cutter head 2 of agear cutter assembly 1 as part of a face hobbing cutter system, as illustrated in FIG. 4. Examples of such systems include Tri-Ac®, Pentac®, and Spiron®. During a face hobbing process, the gear member 12 (workpiece), mounted to a workpiece holder (not shown), and thecutter head 2 continuously rotate, withsuccessive cutter blades 10 engaging successive tooth slots as thegear member 12 being cut. FIG. 4 also shows the face hobbing process and the relative interaction of the gear member 12 (workpiece), in this case the ring gear, as thegear teeth 14 are successfully cut by thecutter blades 10 mounted on thecutter head 2. Thegear member 12 and thecutter head 2 each rotate in the direction of the arrows indicated. - The
cutter blades 10 are generally mounted on thecutter head 2 of the gear cutter assembly in groups. For instance, in the systems offered by The Gleason Works, the cutter blades are arranged on the cutter head in groups of two, each cutter blade pair operating on a different tooth space. In other systems, the cutter blades may be arranged on the cutter head in groups of three. In such systems, there is an inner, outer and rougher blade, which operate to cut the sides and bottom of each tooth space, respectively. The rougher cutter blade is generally provided with both inner and outer cutting edges. Thecutter blade 10 illustrated in the drawings is one of the side cutting blades suitable for use with either a two blade or a three blade group. - While the
ring gear member 12 is illustrated in FIGS. 1 and 2, the gear cutter blade of the present invention is equally applicable to the face hobbing of the pinion member of a gear set. - The face hobbing cutting systems generally utilize cutter blades, which are profile ground at the end user's facility from uniform blanks to afford a variety of specified configurations. As illustrated in FIGS. 1 and 3, the
cutter blade 10 includes ashank 20 and acutting member 22 formed at adistal end 21 thereof. A front face of thecutting member 22 of eachcutter blade 10 is provided, generally only on one side thereof, with acutting edge 24. Thecutting edge 24 comprises afirst section 26 for cutting theside surface 16 of thegear teeth 14, and asecond section 28 for cutting thetop surface 18 of thegear teeth 14. Thus, thefirst section 26 defines a tooth side cutting edge and thesecond section 28 defines a tooth topland cutting edge. - The
first section 26 of thecutting edge 24 extends from a tip 30 of thecutting member 22 at a predetermined axial pressure angle B. The axial pressure angle B of thefirst section 26 of thecutting edge 24 obviously depends on the angle desired for the sides of the gear teeth. As used herein, “axial pressure angle” is defined as the angle between thefirst section 26 of the cutting edge 24 (or tooth profile) and a central axis 11 of thecutter blade 10. - The
second section 28 of thecutting edge 24 is a substantially straight line perpendicular to the central axis 11 of thecutter blade 10, and is characterized by a width W, as illustrated in FIG. 3. - A distance C from the tip30 of the
cutting member 22 to an intersection of thefirst section 26 and thesecond section 28 of thecutting edge 24 is a height of thefirst section 26 of thecutting edge 24 of thecutting member 22. The distance C is substantially equal to the whole depth A of thegear teeth 14. - By modifying the specified blade grinding parameters for forming the
cutter blade 10 from a blank, configuration of thecutting edge 24 can be altered to incorporate thesecond section 28. - Thus, the
gear cutter blade 10 of the present invention cuts theside surface 16 of thegear tooth 14 by means of thefirst section 26 of thecutting edge 24, and simultaneously forms a substantial portion of thetopland surface 18 of thegear tooth 14 by means of thesecond section 28 of thecutting edge 24. Alternatively, thesecond section 28 of thecutting edge 24 is dimensioned to cut anentire topland surface 18 of thegear tooth 14, as illustrated in FIG. 6. - The
cutter blades 10 of the present invention are secured to thecircular cutter head 2 in the conventional manner, and the face hobbing system is operated in the same manner as if conventional cutter blades were employed. However, during a face hobbing process of the present invention, ascutter head 2 continuously rotates, thesuccessive cutter blades 10 cut theside surfaces 16 of thegear teeth 14 by means of thefirst section 26 of thecutting edge 24, and simultaneously machines at least a substantial portion of thetopland surface 18 of thegear tooth 14 by means of thesecond section 28 of thecutting edge 24. - Therefore, with the
gear cutter blade 10 of the present invention, the topland surface is machined on the teeth of a gear or pinion member simultaneously with the tooth side cutting operation. This permits to reduce or completely eliminate the need to finish topland surfaces of the ring gears or pinions. Moreover, the elimination of a subsequent manufacturing operation improves the consistency and accuracy of the gear tooth whole depth, and part quality, as well as reduces manufacturing costs. In addition, the gear cutter blade of the present invention allows for greater manufacturing flexibility, as the cutting edge dimensions can be easily modified, and provides an ability to machine near-net forged parts without requiring precision control of the topland area of machining with an interrupted cut during a blanking operation. - As an example of a working embodiment of the gear cutter blade of the present invention, gear cutting tools having the following characteristics have been designed:
- Material: High Speed Steel or Carbide;
- Axial Pressure Angle B: 5° to 35°;
- Distance C: 0.150″ to over 1.000″;
- Width W: 0.030″ to 0.200″.
- The foregoing description of the preferred embodiments of the present invention has been presented for the purpose of illustration in accordance with the provisions of the Patent Statutes. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments disclosed hereinabove were chosen in order to best illustrate the principles of the present invention and its practical application to thereby enable those of ordinary skill in the art to best utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated, as long as the principles described herein are followed. Thus, changes can be made in the above-described invention without departing from the intent and scope thereof. It is also intended that the scope of the present invention be defined by the claims appended thereto.
