As a further improvement on the present invention, between the He Da outer ring, little outer ring of linking springs not, embed the plastics damping sleeve.Described large outer ring front end has peristome, interference fit the location sealing sheet is installed in this peristome, and described location sealing sheet one end axially contacts with the plastics damping sleeve.This plastics damping sleeve can damping absorb radial vibration.Spring can be eliminated the end play of steel ball and raceway simultaneously.
As a further improvement on the present invention, described large outer ring is provided with the lubricating oil through hole, and the both sides of described lubricating oil through hole are provided with groove, rubber ring is installed to play the effect of sealing to interference fit in this groove.This oilhole can connect the outside oil circuit of stuffing device automatically, realizes at regular time and quantity the grease lubrication that adds to the ingot axle.
As of the present invention, further improve, the outside, described large outer ring also is provided with vibrating sensor.The described vibrating sensor real-time online that matches with external circuit detects the vibration parameters of false twister, and look-ahead ingot axle fault, can also adjust spinning technique according to vibration parameters.
Beneficial effect: the present invention arranges little outer ring between steel ball and large outer ring, and between Yu Da outer ring, little outer ring, embed simultaneously the plastics damping sleeve to reduce radial vibration and axial vibration, the spring be connected between He Da outer ring, little outer ring is set again vertically to eliminate bearing group end play, guarantee the steady operation of spindle axis of false twister, guaranteed the stability of spinning.And the vibrating sensor real-time online that matches with external circuit detects the vibration parameters of false twister, look-ahead ingot axle fault, can also adjust spinning technique to realize the optimization of yarn qualities according to vibration parameters.
The accompanying drawing explanation
Fig. 1 is the structural representation of spindle axis of false twister of the present invention;
Fig. 2 is the structural representation of active ingot axle.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is not used in and limits the scope of the invention be used to the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of various equivalents of the present invention.
Alleged in claims, specification and Figure of description " front ", " ”,“ front side, the place ahead ", refer to along the side of mandrel 1 length direction away from belt pulley 14; Alleged " afterwards ", " rear ", " rear side ", refer to along the side of mandrel 1 length direction near belt pulley 14; Alleged " outward ", " outside ", refer to along mandrel 1 radially away from a side of mandrel 1.
As shown in Figure 1, mandrel 1 one ends are arranged in belt pulley 14, and described belt pulley 14 is provided with travelling gear 13.By the external connection power device, drive belt pulley 14 by travelling gear 13, and then band moving mandrel 1 rotates.The other end of mandrel 1 is free end, and interference fit be provided with locating ring 2, at the middle part of mandrel 1, be provided with large outer ring 4.Large outer ring 4 is that an annular structural part is sleeved on mandrel 1 outside.In large outer ring 4, have the cavity that holds steel ball 11 and associated components, this cavity is in communication with the outside by the lubricating oil through hole 15 be arranged on large outer ring 4, and lubricating oil is injected in cavity by lubricating oil through hole 15.Tightr when making outside oil circuit connect described lubricating oil through hole 15, in the both sides of described lubricating oil through hole 15, also be provided with seal groove, in the sealing groove installation of interference fit rubber ring 8 to play the effect of sealing.
