In addition, the Committee acts as a focus for discussion between members on a wide variety of technical issues. The Technical Committee is lead by its Chairman, Mr J Myers of Newcastle Design Unit, and Vice Chairman, Ron Chester of Sumitomo Cyclo Europe. <P> The BMPTA is active on BSI committees concerned with formulating gear design and manufacturing standards. BMPTA Members have chaired the BSI MCE/5 Standards Committee which has overall responsibility for some twenty BSI standards and which also liaises with the BSI MTE/16 Committee for gear-forming tools. <P> Mr Alan Thompson of Gear Technology Ltd chairs the MCE/5 Committees which shadows the activities of the ISO TC 60 (Gears) working groups. The committee members, see below, also represent the interests of the UK gear industry at the ISO meetings and can thus influence the formulation of future international standards relating to gears. <P> <CENTER> <TABLE BORDER=1 BGCOLOR="#FFFFFF"> <TR> <TH COLSPAN=4>UK Representatives on ISO Working and ad hoc Groups</TH> </TR> <TR> <TH ROWSPAN="2">Working<BR>Group</TH> <TH ROWSPAN="2">Subject Area</TH> <TH COLSPAN=2>Representative</TH> </TR> <TR> <TH>Name</TH> <TH>Organisation</TH> </TR> <TR> <TH COLSPAN=4 ALIGN=left> Technical Committee TC60:-</TH> </TR> <TR> <TD>SC1</TD> <TD>Sub Committee 1</TD> <TD>A M Thompson</TD> <TD><A HREF="../members/default.asp?Company=31" TARGET="data">Gear Technology Ltd</A></TD> </TR> <TR> <TD>SC1</TD> <TD>Sub Committee 1 Secretary</TD> <TD>B Upton</TD> <TD>Consultant</TD> </TR> <TR> <TD>WG2</TD> <TD>Accuracy</TD> <TD>R Frazer</TD> <TD><A HREF="../members/default.asp?Company=95" TARGET="data">Gear Design Unit (Newcastle University)</A></TD> </TR> <TR> <TD>WG4</TD> <TD>Geometry</TD> <TD>H Kohler</TD> <TD>Consultant</TD> </TR> <TR> <TD>WG6</TD> <TD>Load Capacity of Spurs and Helicals</TD> <TD><A HREF="http://www.staff.ncl.ac.uk/e.j.myers"> EJ Myers </A></TD> <TD><A HREF="../members/default.asp?Company=95" TARGET="data">Gear Design Unit (Newcastle University)</A></TD> </TR> <TR> <TD>WG7</TD> <TD>Worms</TD> <TD>M Fish</TD> <TD><A HREF="../members/default.asp?Company=123" TARGET="data">Holroyd</A></TD> </TR> <TR> <TD>WG9</TD> <TD>N&V Acceptance Codes</TD> <TD>J Curtis</TD> <TD><A HREF="../members/default.asp?Company=4" TARGET="data">Allen Gears</A></TD> </TR> <TR> <TD>WG10</TD> <TD>Enclosed Drives</TD> <TD>R Chester</TD> <TD><A HREF="../members/default.asp?Company=85" TARGET="data">SHI-Cyclo Drive Europe</A></TD> </TR> <TR> <TD>WG11</TD> <TD>High Speed Enclosed Drives (API)</TD> <TD>P Simmons</TD> <TD>Consultant</TD> </TR> <TR> <TD>WG12</TD> <TD>Lubricants</TD> <TD>D Parkins</TD> <TD>Consultant</TD> </TR> <TR> <TD>WG13</TD> <TD>Load Capacity of Bevels</TD> <TD>P Morton</TD> <TD><A HREF="../members/default.asp?Company=24" TARGET="data">David Brown Group plc</A></TD> </TR> <TR> <TD>WG14</TD> <TD>Materials</TD> <TD>DW Ingham</TD> <TD><A HREF="../members/default.asp?Company=24" TARGET="data">David Brown Group plc</A></TD> </TR> <TR> <TD>WG6 AH3</TD> <TD>Load Distribution Factors</TD> <TD><A HREF="http://www.staff.ncl.ac.uk/e.j.myers"> EJ Myers </A></TD> <TD><A HREF="../members/default.asp?Company=95" TARGET="data">Gear Design Unit (Newcastle University)</A></TD> </TR> <TR> <TD>WG6 AH4</TD> <TD>Thermal Ratings</TD> <TD>R Chester</TD> <TD><A HREF="../members/default.asp?Company=85" TARGET="data">SHI-Cyclo Drive Europe</A></TD> </TR> <TR> <TD>WG6 AH6</TD> <TD>Dynamic Factors</TD> <TD><A HREF="http://www.staff.ncl.ac.uk/e.j.myers"> EJ Myers </A></TD> <TD><A HREF="../members/default.asp?Company=95" TARGET="data">Gear Design Unit (Newcastle University)</A></TD> </TR> <TR> <TD>WG6 AH7</TD> <TD>Tooth Root Stress Calculations</TD> <TD><A HREF="http://www.staff.ncl.ac.uk/e.j.myers"> EJ Myers </A></TD> <TD><A HREF="../members/default.asp?Company=95" TARGET="data">Gear Design Unit (Newcastle University)</A></TD> </TR> <TR> <TH COLSPAN=4 ALIGN=left>Technical Committee TC 14 :- </TR> <TR> <TD>WG1</TD> <TD>Splines</TD> <TD><A HREF="http://www.staff.ncl.ac.uk/e.j.myers"> EJ Myers </A></TD> <TD><A HREF="../members/default.asp?Company=95" TARGET="data">Gear Design Unit (Newcastle University)</A></TD> </TR> </TABLE> </CENTER> <P> The Technical Committee award of a prize for the best degree final year project prize 2000 was to Jake Sisson, Allen Gears, for his project report "Evaluation of Epicyclic Gearbox Efficiency" This prize is being supported by the IMechE. <P> The meetings are often rounded off by technical presentations and have included an overview of the STEP Programme AP226 by V Kozousek, Lloyd's Register of Shipping, the progress of ISO 3595 "Gears - Industrial Enclosed Gear Drives" and an overview of Cycloidal Gears, both by R Chester, SHI. <P> <A NAME="seminars"></A><H2>Technical Seminars</H2> <FONT SIZE="2"><A HREF="#top">Top</A></FONT><BR> The Technology Transfer events, which have each been run on an eighteen-month cycle for the past ten years is largely an administrative matter for BMPTA Central Staff although the Committee is instrumental in bringing new seminars on line (<I>for latest seminars click <A HREF="../news/latest.htm">here</a></I>). However, we are responsive to feedback from attendees and we are currently putting together further seminar proposals. <P> The Technical Committee and its immediate contacts have expertise in all aspects of gearing. The Technical and Training Committees have jointly run a series of Seminars, Workshops and <A HREF="../training/data.htm#lectures" TARGET="data">On-site Visits</A> in recent years to transfer this technology and experience. <P> These events are organised on a wide range of technical subjects - Table 2 gives some examples of the current titles - which are designed to help delegates from both Member and non-Member companies to keep abreast of the latest gearing technology. BMPTA Members enjoy discounted delegate attendance fees. <P> The programme of workshops and seminars are held in rotation on a cycle of about 18 months.

It also encouraged the setting up of the National Gear Metrology Laboratory at Newcastle which gained NAMAS (National Measurement Accreditation Service) accreditation in 1988 and is now responsible for gear standards and gear metrology throughout the UK. <P> By lobbying funding organisations - in particular the EPSRC, the BMPTA has been instrumental in encouraging more research in gearing at other universities, notably at Huddersfield and Cardiff, as well as Cambridge, Imperial college and Birmingham University. <P> The BMPTA commissioned a comprehensive world-wide literature survey of gearing related research, which was published as the `State of the Art Survey'. Relevant data was extracted from this and <A HREF="../forms/data.htm#papers">data items</A> prepared for BMPTA Members on gear design and manufacture and a gear research programme formulated to meet the needs of the UK gearing industry. The Engineering and Physical Sciences Research Council (EPSRC) and the Department of Trade and Industry (DTI) supported this research and have provided generous funding. <A NAME="grf"></A><H3>The BMPTA Research Committee</H3> <FONT SIZE="2"><A HREF="#top">Top</A></FONT><BR> <DL> <DT><A HREF="../research/index.htm" TARGET="_parent">Research programmes completed or underway:</A> </DL> In 1991, the DTI initiated a multi-£M gearing research programme to be co-ordinated and managed by the BMPTA on behalf of the UK power transmissions industry. In order to provide a mechanism to allow non-Members to participate, the Association was reconstituted as a company limited by guarantee and the Gear Research Council (GRC) closed to enable the creation of a Gear Research Foundation (GRF) to manage the new research programmes. <P> On the 1st January 2000 the GRF was re organised as the BMPTA Research Committeewhich will benefit the Research and other BMPTA Committee work and reduce the costs of the research activities. <A NAME="epsrc"></A><H3>EPSRC Funded Research</H3> <FONT SIZE="2"><A HREF="#top">Top</A></FONT><BR> <TABLE ALIGN="RIGHT" BORDER="1"> <TR><TD><IMG SRC="../images/frenco.jpg" WIDTH=250 HEIGHT=279 BORDER=0 ALT=""></TD></TR> <TR><TD><CENTER><FONT SIZE="2">Gear metrology equipment:<BR>involute/lead gear tester</FONT></CENTER></TD></TR> <TR><TD><CENTER><FONT SIZE="1">Courtesy of <A HREF="../members/default.asp?Company=94" TARGET="_self">The University of Huddersfield</A></FONT></CENTER></TD></TR> </TABLE> The BMPTA has also supported University research which was predominantly Engineering and Physical Science Research Council (EPSRC) funded.
