Abstract
Abstract A coil winding apparatus having one or more wire guides fixedly mounted on respective spindles which are mounted on a housing for axial movement relative thereto and for rotational movement about their axes. Each spindle includes a main front bearing in the vicinity of its wire guide and a main rear bearing in the housing. The main rear bearings are movable axially with the spindle but the front bearings are shiftable axially relative to the spindle.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
133 words
An apparatus for winding coils for electric machines and the like comprising: a housing, a wire guide, means for fixedly mounting the wire guide on an elongated spindle, means for mounting said spindle on said housing for rotational and axial movement relative thereto, said mounting means including a front rotary bearing which includes means for mounting the spindle in the vicinity of the wire guide and a rear rotary bearing which includes means for mounting the spindle rearwardly of the said front bearings, and said front bearing mounting means including means for permitting shifting of the front bearing axially relative to said spindle and relative to said housing so that the front bearing can be moved towards and away from the wire guide of the spindle for given axial positions of the spindle.
Claim 2
Independent Claim
133 words
An apparatus for winding coils for electric machines and the like comprising: a housing, a wire guide, means for fixedly mounting the wire guide on an elongated spindle, means for mounting said spindle on said housing for rotational and axial movement relative thereto, said mounting means including a front rotary bearing which includes means for mounting the spindle in the vicinity of the wire guide and a rear rotary bearing which includes means for mounting the spindle rearwardly of the said front bearings, and said front bearing mounting means including means for permitting shifting of the front bearing axially relative to said spindle and relative to said housing so that the front bearing can be moved towards and away from the wire guide of the spindle for given axial positions of the spindle.
Claim 3
Dependent Claim
26 words
An apparatus according to claim 1, including means mounting said spindle and said rear bearings for common movement together axially of said spindle in said housing.
Claim 4
Dependent Claim
32 words
An apparatus according to claim 2, including rotary drive means for rotating said spindle and means mounting said spindle and said rear bearing for axial movement relative to said rotary drive means.
Claim 5
Dependent Claim
19 words
An apparatus according to claim 2, including means for rotating the spindle and means for moving the spindle axially.
Claim 6
Dependent Claim
65 words
An apparatus according to claim 4, said means for rotating comprising a spindle gear fixedly connected to the spindle and a drive gear drivingly engaging the spindle gear and means mounting the drive gear for movement in a direction parallel to the spindle axis such that driving engagement is maintained between the drive gear and the spindle gear at all axial positions of the spindle.
Claim 7
Dependent Claim
52 words
An apparatus according to claim 5, said means for moving the spindle axially including a screw threaded shaft rotatably mounted in the housing and a screw threaded nut threaded onto the shaft and fixed thereto for axial movement with the shaft, whereby rotation of the shaft causes axial movement of the spindle.
Claim 8
Dependent Claim
39 words
An apparatus according to claim 6, including a front bearing plate, said front bearing being mounted in said front bearing plate, and power means for moving said front bearing plate and hence said front bearing relative to said housing.
Claim 9
Dependent Claim
40 words
An apparatus according to claim 5, including a splined drive shaft fixed for rotation in the housing but prevented from moving axially therein, said drive gear mounted on the spinle shaft for rotation therEwith and for axial sliding movement therealong.
Claim 10
Dependent Claim
24 words
An apparatus according to claim 1, including means for positioning said front main bearing between the outside of the housing and the wire guide.
Claim 11
Dependent Claim
24 words
An apparatus according to claim 1, including means for positioning said front main bearing between the outside of the housing and the wire guide.
Claim 12
Dependent Claim
57 words
An apparatus according to claim 1, including a plurality of said spindles, each having a said wire guide and said front and rear bearings, a front bearing plate mounting all said front bearings and located between the wire guides and the housing, and a rear bearing plate mounting all said rear bearings and located in the housing.
Claim 13
Dependent Claim
56 words
An apparatus according to claim 11, including rotating means for rotating the spindles and axial means for moving the spindles axially, both said rotating means and said axial means connected to the spindles through means connected to the rear bearing plate, and a guide bar mounted in the housing for guiding the front bearing plate axially.
