Definitions
- This invention relates generally to a swing motor mounting arrangement and more particularly to a swing motor connected between a vehicle frame and a mast frame for selectively swinging the mast frame relative to the vehicle frame.
- Construction vehicles such as backhoes, include a swing motor mounted between a tractor frame and a mast frame for selectively swinging a boom attached to the mast frame to various work positions. It has proven desirable to provide a mounting arrangement for the swing motor whereby the motor may be expeditiously installed and removed for repair or replacement purposes. In addition, the mounting arrangement should exhibit sufficient structural integrity to prevent undue wear of component parts thereof, such as spline connections, pins, and bearings. Swing motor mounting arrangements of this type are disclosed in U.S. Patent No. 3,758,941, issued to James S. Jackson et al. on September 18, 1973. The present invention is directed to overcoming one of more of the problems as set forth above.
- a swing motor mounting arrangement includes first and second pivotally interconnected frames with a housing of a swing motor being secured to the first, frame, andwith a shaft of the motor being exposed at opposite ends of the housing.
- the improved mounting arrangement further includes a pair of spaced first bracket means for pivotally mounting the second frame on the first frame, and a pair of spaced second bracket means for securing opposite ends of the motor shaft to the second frame directly.
- first and second bracket means provide a structurally integrated arrangement for protecting various spline connections, pins, and bearings of the mounting arrangement against undue wear to prolong the service life thereof.
- Figure 1 is a side elevatiohal view of a swings motor mounting arrangement embodiment of the present invention
- Figure 2 is a top plan view of the mounting arrangement, taken in the direction of arrows II-II in Figure 1
- Figure 3 is an enlarged sectional view of a spline connection of the mounting arrangement, taken in the direction of arrows III-III in Figure 1.
- FIG. 1 illustrates a swing motor mounting arrangement 10 comprising a swing motor 11 having a housing 12 and a shaft 13 rotatably mounted in. the housing. Opposite ends 14 of shaft 13 project beyond housing 12 in exposed relationship and are secured to a mast frame 15 in a manner hereinafter described.
- Motor housing 12 is secured to a frame 16 of a tractor or the like by a connection 17 and mast frame 15 is pivotally mounted on tractor frame 16 whereby rotation of shaft 13 relative to housing 12 will selectively swing mast frame 15 horizontally relative to tractor frame 16 to various work positions.
- Mast frame 15 has a boom 18 pivotally mounted thereon, along with a rod 19 of a doubleacting hydraulic cylinder connected to a dipper stick (not shown) pivotally mounted on the boom.
- Swing motor 11 has at least one vane (not shown) secured on shaft 13 to selectively rotate the shaft relative to housing 12 in response to communication of pressurized hydraulic fluid therein.
- each bracket means 20 includes a bifurcated brackets 21 secured on mast frame 15 to extend rearwardly therefrom, a single bracket 22 secured on tractor frame 16 to extend rearwardly therefrom, and a pivot pin 23. Pivot pin 23 is suitably secured to bracket
- bracket means 26 Each bracket means 26 includes a bracket 27 secured to mast frame 15 to extend rearwardly therefrom and a plate 28, shown in the form of a cap, releasably secured to bracket 27 by fastening means shown in the form of a pair of bolts 29. If so desired, a tubular centering dowel 30 may be inserted between bracket 27 and plate 28 to aid in the securance of each bolt 29 to bracket 27, as shown in Figure 3.
- Each plate 28 has spline teeth 31 formed therethrough to engage similar spline teeth 32 formed on a respective end 14 of motor shaft 13. It can be seen in Figures 1 and 2 that expeditious and precise mounting of motor 11 on mast frame 15 is facilit ated by allowing plates 28 to be initially secured to the ends of motor shaft 13 at splines 31, 32 and by thereafter securing the plates to brackets 27 by bolts 29. Subsequently, brackets 22 of tractor frame 16 may be properly positioned within bifurcated brackets 21 of mast frame 15 to permit pivot pins 23 to be secured in place by bolts 24 and also to permit attachment of motor housing 12 to tractor frame 16 by connection 17.
- aligned bores 33 and 34 may be formed through brackets 21 and 22, respectively, to releasably receive a swing lock pin 35 therein to lock mast frame 15 against swinging movements relative to tractor frame 16 during roading of the vehicle, for example.
- Swing motor mounting arrangement 10 finds particular application to backhoes which include mast frame 15, adapted for swinging movements on tractor frame 16 in response to actuation of swing motor 11.
- frame 16 has been referred to as a "tractor frame,” it should be understood that in many backhoe applications frame 16 would constitute a mounting frame slidably mounted for lateral movements on a tractor frame proper to permit selective positioning and locking of mast frame 15 at a desired lateral position at the rearward end of the tractor.
