Abstract
A spindle base is provided wherein one end keeps close and the other keeps open; a site at the end with a distance about 2mm from the roof is provided with a cone with an angle Alpha 7 degrees; a site at the other end with a distance about 2mm from the bottom is provided with a cone with the angle Beta 20 degrees. At the same time, the bottom is provided with a hole connected with an inner cavity. The bottom of the inner cavity of the spindle base presents a cone, with a taper angle of 90 degrees, the bottom of which is an arc with a diameter R of 0.7mm; the superior section of cone is expanded to constitute a cone with a taper angle of 120 degrees and a small height about 0.3mm; then, the cone is connected with a tapered inner cavity with a taper angle of 15 degrees 44 minutes; The spindle base is arranged in the elastic tube the surface of which is provided with a shock absorption spring and a positioning tube outside by a sleeve installation. Then, a spindle base sleeve is arranged outside the elastic tube to constitute a spindle base component to serve a spinning machine wherein the spindle positioned in the elastic tube can bear a rotation speed of 20000 rpm but keep stable.
Description
Technical field
The utility model relates at the bottom of a kind of ingot, and it and elastic tube make up and be contained in the bolster tube, are set with vibration absorbing spring and locating sleeve on the elastic tube, are the critical pieces of spinning machine, belong to the technical field of spinning machine.
Background technology
Existing spinning machine bolster sub-assembly is to adopt nylon ring and sleeve pipe, and its bolster tube and bolster nut join together its processing is difficult for, and is difficult to adjustment when using, and spinning speed is lower than 1200 rev/mins, and stability is very poor during running.The applicant has applied for new bolster sub-assembly patent recently, and its elastic tube and bolster combination are set with weakening spring and locating sleeve on the elastic tube, refill bolster tube.This sub-assembly makes spinning speed bring up to 18000 rev/mins, and more evenly and in the running stability is better to make yarn.
Summary of the invention
The purpose of this utility model is will provide at the bottom of a kind of ingot, and it can be used as the bolster assembly part with the elastic tube combination.
Structure at the bottom of the ingot is the end sealing of (7) at the bottom of the ingot and the other end opens wide, there is a α angle its end from end face 2mm place be 7 ° taper (11), it is 28 ° taper (12) that the other end highly locates also to have the β angle from bottom surface 2mm, and the bottom has an aperture (10) to communicate with inner chamber (8) simultaneously.The bottom (13) that is 90 ° of tapers (14) at the bottom of the ingot bottom the inner chamber of (7) (8) is the arc of 0.7mm with R, the taper (15) of 120 ° of cone angles is expanded on the top of taper again, and its highly less 0.3mm that is about, then with cone angle be 15 ° 44 ' conical internal cavity (8) join.
Advantage is that concave ball shape at the bottom of the ingot can bear 20000 rev/mins running up at the bottom of the ingot, can bear dynamic operating load 100g～1000g, when spindle runs up, oil lubrication is in uninterrupted automatic circulating lubricating at the bottom of the ingot, inwall and movable body form the vibration source that certain oil film circumference is received the movable body that shakes at the bottom of the ingot in high-speed cruising, can guarantee the spindle proper motion, its stability better.
Description of drawings
Fig. 1. elastic tube combination schematic diagram
Fig. 2. schematic diagram at the bottom of the ingot
By Fig. 1, elastic tube (5) is contained in the bearing block (3), elastic tube (5) has an inner chamber (6), bearing block (3) has a step (4), bearing (2) is contained in the bearing block (3), and by gland (1) roof pressure sealing, elastic tube (5) right-hand member pack into (7) at the bottom of the ingot, left end contacts with the step (9) of elastic tube (5) at the bottom of the ingot, and (7) side has an aperture (10) to communicate with the inner chamber (8) of (7) at the bottom of the ingot at the bottom of the ingot.
By Fig. 2, an end of (7) sealing at the bottom of the ingot and the other end opens wide, there is a α angle its end from end face 2mm place be 7 ° taper (11), and it is 28 ° taper (12) that the other end highly locates also to have the β angle from bottom surface 2mm, and the bottom has an aperture (10) to communicate with inner chamber (8) simultaneously.The bottom (13) that is 90 ° of tapers (14) at the bottom of the ingot bottom the inner chamber of (7) (8) is the arc of 0.7mm with R, the taper (15) of 120 ° of cone angles is expanded on the top of taper again, and its highly less 0.3mm that is about, then with cone angle be 15 ° 44 ' conical internal cavity (8) join.
The specific embodiment
(7) at the bottom of the ingot shown in Figure 2 are contained in the elastic tube (5), there is flight on elastic tube (5) surface, places the weakening spring in its groove, spring surface suit one location sleeve pipe (figure slightly), bolster tube (figure slightly) is housed is structure bolster sub-assembly in the outside then, and the spindle of spindle just is inserted in the elastic tube.Because the structure at the bottom of the ingot makes its speed that can bear 20000 rev/mins, working order is very stablized and friction, form the vibration source that oil film can be received the movable body that shakes at the bottom of the ingot between inwall and the spindle.
Claims (1)
1. at the bottom of the ingot, it is characterized in that the end sealing of (7) at the bottom of the ingot and the other end opens wide, it is 7 ° taper (11) that there is a α angle its end, it is 28 ° taper (12) that the other end also has the β angle, the bottom has an aperture (10) to communicate with inner chamber (8) simultaneously, to be the bottom (13) of 90 ° of tapers (14) be the arc of 0.7mm with R the inner chamber of (7) (8) bottom at the bottom of the ingot, and the taper (15) of 120 ° of cone angles is expanded on the top of taper again, then with cone angle be 15 ° 44 ' conical internal cavity (8) join.
