Abstract

Abstract A power transmitting drive apparatus for distributing power from a single power source to a plurality of outputs for driving various mechanism, such as fluid pumps. A fixedly located power input means is rotatably mounted in the housing and furnishes power to two intermediate gear means, the intermediate gear means then each transmitting the power to two output gear means which are attached to the load, such as fluid pumps or the like. The output gear means is at a fixed location in the housing and need not be changed. The intermediate gear means as well as the input gear means are changeable as to size and number of teeth to effect different gear ratio changes. The arrangement is such that the intermediate gears can be replaced with others of different size, but at the same time, the housing requires no additional mounting holes for mounting the intermediate gears in various positions. Instead, various types of gear support means are provided in fixed locations in the housing so as to be able to shift the center of rotation of the intermediate gears along a certain predetermined line.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 229 words
A power transmitting drive apparatus for transmitting power from a single input shaft to a plurality of output gears, said apparatus comprising, a housing, means for rotatably mounting an input shaft in said housing and an input gear fixed to said shaft, at least two output gears rotatably journalled in said housing at fixed locations, an opening in said housing, an intermediate gear rotatably journalled within said housing and in constant mesh with said output gears and with said input gear, an eccentric support for adjustably mounting said intermediate gear in said housing, said support having a mounting portion for mounting in said opening and an inwardly extending eccentric portion eccentrically arranged with respect to said mounting portion, said support being removably attached to said housing and mounted in said opening and having its said eccentric portion extending into said housing, said intermediate gear being rotatably journalled on said inwardly extending eccentric portion whereby said support may be removed from said opening and replaced with a support having an inwardly extending portion of different eccentricity to thereby accommodate an intermediate gear of different size in constant mesh with said output gears, said eccentric support being adjustably positioned in said opening to position its eccentric portion in either one of two positions centrally along a line extending normal to a line through the center of rotation of said output gears.
Claim 2
Dependent Claim 229 words
A power transmitting drive apparatus for transmitting power from a single input shaft to a plurality of output gears, said apparatus comprising, a housing, means for rotatably mounting an input shaft in said housing and an input gear fixed to said shaft, at least two output gears rotatably journalled in said housing at fixed locations, an opening in said housing, an intermediate gear rotatably journalled within said housing and in constant mesh with said output gears and with said input gear, an eccentric support for adjustably mounting said intermediate gear in said housing, said support having a mounting portion for mounting in said opening and an inwardly extending eccentric portion eccentrically arranged with respect to said mounting portion, said support being removably attached to said housing and mounted in said opening and having its said eccentric portion extending into said housing, said intermediate gear being rotatably journalled on said inwardly extending eccentric portion whereby said support may be removed from said opening and replaced with a support having an inwardly extending portion of different eccentricity to thereby accommodate an intermediate gear of different size in constant mesh with said output gears, said eccentric support being adjustably positioned in said opening to position its eccentric portion in either one of two positions centrally along a line extending normal to a line through the center of rotation of said output gears.
Claim 3
Dependent Claim 157 words
A power transmitting drive apparatus for transmitting power from a single source to a plurality of power consuming mechanisms, said apparatus comprising, a housing, rotatable power input means positively positioned within said housing and operatively connected to a source of power, at least two intermediate power transmitting means rotatably driven by said power input means and supported within said housing by supports, each of said intermediate means driving a plurality of power output means positively positioned and supported within said housing and operatively connected to said power consuming mechanisms, the improvement comprising each of said supports having an eccentric portion on which intermediate means is rotatably mounted, said support being removably secured to said housing and being rotationally adjustable to position its eccentric portion in either one of two positions located along a line extending normal to a line passing through the center of rotation of the two power output means which mesh with its intermediate means.
Claim 4
Dependent Claim 157 words
A power transmitting drive apparatus for transmitting power from a single source to a plurality of power consuming mechanisms, said apparatus comprising, a housing, rotatable power input means positively positioned within said housing and operatively connected to a source of power, at least two intermediate power transmitting means rotatably driven by said power input means and supported within said housing by supports, each of said intermediate means driving a plurality of power output means positively positioned and supported within said housing and operatively connected to said power consuming mechanisms, the improvement comprising each of said supports having an eccentric portion on which intermediate means is rotatably mounted, said support being removably secured to said housing and being rotationally adjustable to position its eccentric portion in either one of two positions located along a line extending normal to a line passing through the center of rotation of the two power output means which mesh with its intermediate means.
Claim 5
Dependent Claim 204 words
A four pump drive apparatus for transmitting power from a single power source to each of a plurality of fluid pumps, said apparatus comprising: a housing, a drive gear located and rotatably supported within said housing and being operatively connected to a source of power, a pair of idler gears driven by said drive gear and supported within said housing, said idler gears being supported by supports mounted in openings formed in said housing, four power output gears operatively connected to and driving four pumps, said output gears each being rotatably supported in said housing with a pair of said output gears being driven by each of said idler gears, said supports each comprising an eccentric portion on which an idler gear is rotatably mounted, said support being adjustably mounted in said housing openings to position its eccentric portion in either one of two positions located along a line extending normal to a line passing through the center of rotation of the two output gears which mesh with its idler gear, whereby each of said idler gears can be mounted with its center of rotation positioned at various locations, and different sized idler gears can be utilized to drive each pair of output gears.
