It shall be the responsi- bility of the pumping unit manufacturer to design sleeve bearings, based on available test data and field experience, which are comparable in per- formante to anti-friction bearings designed for the Same operating load
39、s and Speeds. 2.15 Installation Markings. Clearly defined and readily usable markings shall be provided on the end Cross members of the base to indicate the vertical pro- jection of the walking beam centerline. The markings shall be applied with a chisel, Punch, or other suitable tool. 2.16 Marking.
40、 Esch pumping-unit structure shall be provided with a name plate substantially as shown in Fig. 2.2. At the discretion of the manufacturer, the name plate may contain other non-conflicting and appropriate information, such as model number or lub- rication instructions. 2.17 In Order that the torque
41、on a reducer may be determined conveniently and accurately from dyna- mometer test data, manufacturers of pumping units shall provide. on request of the purchaser, stroke and torque factors for each 15deg Position of the trank. An approved form for the Submission of these data is shown in Appendix A
42、. *Uscrs of this specification should note that there is no langer a requircment for marking a product with the API monogram. The Amcrican Petroleum Institute continues to licensc use of the monogram on products covered hy this specification but it is administered by the staff of the Institute separ
43、ately from the specification. The policy describing licensing and use of the monogram is contained in Appendix H. herein. Ko other use of the monogram is permitted. SECTION 3 PUMPING-UNIT REDUCERS 3.1 SCOPE Applicability. This Specification is applicable to en- closed Speed reducers urherein the inv
44、olute gear tooth designs include helical and herringbone gearing. This Specification is intended primarily for beam-type pumping units. Limitations. The rating methods and influences identified in this Specification are limited to Single and multiple Stage designs applied to oilfield pumping units,
45、in which the pitch-line velocity of any Stage does not exceed 5000 feet per minute and the Speed of any shaft does not exceed 3600 revolutions per minute. 3.2 RESPONSTBILTTY Gear Reducer Designers. Professionals using this Specification should realize that it is quite difficult to identify and offer
46、 solutions to all the influences affect- ing a gear reducer. For this reason, it is recommended that this Specification be used by engineers with signif- icant experience in mechanical Systems. Reducers rated under this Specification. and properly applied. installed, lubricated and maintained, shall
47、 be capable of safely carrying the rated peak torque under normal oilfield conditions. Rating Factors. The allowable stress numbers in this Specification are maximum allowed values. Less con- servative values for other rating factors in this Specifi- cation shall not be used. Metallurgy. The allowable stress numbers, s, and S at? included in this Specification are based on commer- cial ferrous material manufacturing practices. Hard- ness, tensile strength, and microstructure are the crite- ria for allowable stress numbers. Reasonable levels of cleanliness and
