Definitions
- This invention relates to spindles for spinning machines, doubling machines and other machines for the treatment of spun textile flbres or filaments, and refers more particularly to high-speed spindles of the type embodying a roller-bearing insert.
- roller-bearing insert for a spindle is machined from solid bar stock or fabricated from steel tubing.
- the head for receiving the roller race and the body or pillar hereinafter for convenience referred to as the body, are machined in one piece from a length of solid bar stock of a size sufllcient to allow for the formation of the head, which is of larger diameter than the body, thereby incurring a waste of metal, the body being bored to the required diameter to receive the spindle, and at its lower end being formed with a shoulder to provide an abutment for a footstep driven in from the bottom and secured in position by clinching the lower end of the tubular body over the adjacent end of the footstep, whil the head is bored to the required diameter to receive the roller race, which is secured in position in the head by clinching the upper end of the tubular head over the upper end of the roller hearing.
- a tongue is stuck-out from the wall of the body to provide a projection to prevent turning movement of the roller-bearing insert relatively to the bolster.
- roller-bearing insert as used for spindles for machines for working with rayon fibres
- the head and the body of the roller-bearing insert are machined in one piece from a solid bar, the body being formed with an intermediate tapered portion of larger diameter than the lower portion to provide a taper fitting surface for the insert, which is a press fit into the bolster.
- a groove or slot is machined into the side of the tapered portion to provide a drain for spent oil.
- the roller race and the footstep are secured in their respective positions in similar manner to that before-debody of the roller-bearing insert is fabricated l! from a steel tube which requires to be machined, while the head to receive the roller race is a separate machined part subsequently brazed onto the body.
- the footstep usually made of bronze, is fixed in the body by means of a screw-threaded sleeve at the bottom, said sleeve being finallyv secured in position by splaying the lower end of the body into a slot in the end of said sleeve.
- the holding ring is made from steel tubing and has one slot to receive the anti-rotation projection on the body and the point of the retaining screw of the bolster.
- the lower ring has oil drain-oil slots machined in the outer surface thereof.
- a roller-bearing insert formed as last described entails a considerable amount of machining and assembling.
- the thickness of the wall of the body in inserts as described reduces the space available for oil contained in the base of the bolster.
- roller-bearing inserts overcomes the disadvantages of the roller-bearing inserts described and reduces machining to a minimum by providing a simplified constructionof roller-bearing inserts in which the body is formed as a deep drawn pressing flanged at its upper part, the head being a separate machined part, shouldered to form a seating for the flanged body, the body and the head being held together by clinching the roller race in the head above the flange, thus obviating welding, brazing or screwing; or the body and head may be formed throughout as a single deep drawn pressing, the roller race being clinched in the head.
- the present invention has for a principal object the provision of a spindle for textile machinery including a bolster housing a roller-bearing insert having a body formed as a relatively thin walled deep drawn pressing, a head for receiving a roller race, a roller race disposed in said head, a footstep located in the lower part of said body, in which the body, head, roller race and footstep are secured together as a unit without welding, brazing or screwing.
