Definitions
- This invention relates to a gas compressor and, more particularly, to improvements in the mounting of a synchronizing-balancing mechanism in the compressor.
- the invention is illustrated as having a motor operating an axially reciprocable piston in a compressor but could be used to operate other types of energy-absorbing devices.
- the invention may be used in a reverse arrangement with the power means located where the piston is located and the energy absorbing device located where the motor is shown.
- Compressors similar to the one of this invention are illustrated in my U.S.A. patents numbers 3,944,299, 3,861, 222 and 3,861,223, but they, like other prior art compressors, have transversely extending supports for the pinions ⁇ f the synchronizing-balancing mechanism formed integrally with the compressor's housing, which requires that slots be provided in the outer racks' connecting plates for the pinion shafts to extend through, and the surface of each of the supports must be carefully machined to provide a guide surface for the outer racks unit.
- This invention obviates the above-mentioned costly construction and additionally reduces the overall manufacturing cost by providing a U-shaped clip on axially extending pinion supports that perform the dual function of pinion shaft retainers and inexpensive guide and bearing surfaces for the outer racks, as well as the pinions.
- Figure 1 of the drawing is a schematic and vertical sectional view of one embodiment of the invention
- Figure 2 is a similar fragmentary view taken along line 2-2 of Fig. 1;
- Figure 3 is a sectional view taken along line 3-3 of ⁇ ig. 2;
- Figure 4 is an enlarged, fragmentary and sectional view of a modified form of support means for pinion shafts
- Figure 5 is a fragmentary sectional view taken along line 5-5 of Fig. 4; and Figure 6 is a fragmentary, sectional view, similar to that of Fig. 2, of a modification of the crankcase housing section.
- the compressor has a lower crankcase housing section 11 with a base extension 11a on which an electric motor 12 is mounted. Intermediate the ends of section 11 is an inwardly extending integral flange 13 with an axially extending sleeve-like support 14. Slots extending downwardly from the top are formed in the support 14 to provide spaced extensions 15 and 16 (see Fig. 2) to receive pinions 17 therebetween. The pinions are supported on shafts 18 extending through holes 19 and 20.
- a double rack member 21 extends between the pinions 17 and has a piston rod upper extension 21a that extends through a seal 22 in a partition wall 23, through a compressor piston 24 and through a bearing sealing 25 in the end wall 26 of cylinder 27. If desired, the piston rod may extend further into additional compressor cylinders, not shown.
- the double rack also has a lower extension 21b, in the form of a piston, that serves as a cro ⁇ shead. It is guided by a sleeve-like bearing member 28 with an external annular flange 28a that is bolted to the under side of support member 13.
- a guide bore 28b in the bear ing member is adapted to be formed either through an opening 11b through the base of section 11, if the guide is attached to section 11 before the guide bore is formed, or is integral with the section as shown in Fig.6, or may be formed through the upper end of the section 11 and through the enlarged opening 15a and 16a in the pinion support portions 14, 15 and 16 (see also Fig. 6).
- opening 11b is provided, however, the enlargement 15a and 16a could be eliminated and vice-versa.
- crankshaft extends through a bearing 30 secured in an opening 31 formed in a side wall of section 11, while the section is in a machine which drills holes 19 and 20, through a window 11c. This assures that the hole 31 will be exactly parallel to the holes 19 and 20 for quick and accurate assembly.
- the crankshaft carries a pair of counter- balanced crank arms 32 connected to a connecting rod 33 by a pivot pin 34.
- the connecting rod is pivotally connected to cros ⁇ head 21b by pin 35.
- the outer end of crankshaft 29 carries a pulley 36 which is connected to a smaller pulley 37 on motor 12 by a V-belt 38.
- a pair of parallel racks 39 rigidly connected together by plates 40.
- Fig. 6 is the same as that of Figs. 1-3 except that the cros ⁇ head guideportion 228 is cast integrally with the pinion support 214 and section 211. Also no opening is provided in the base of the section a ⁇ the bore 228b is drilled from the top and through the enlarged opening 215a-216a.
- the angular re lationship of the member 28 is not critical as the guide 28 fits snugly in a bore through flange 13, that also has a machined pad to be engaged by the flange 28a.
- the bores 19, 20, 31, 13a, 15a and 16a are all formed at the same time, when in a drilling machine, there is no time- consuming alignment diffulties.
