Background technology
The cylindrical central sleeve structure of circular knitting machine as shown in Figure 1 in the prior art, holder a8 requires to be fixed in the cylindrical central sleeve 5a with three straight pin opsition dependents, radial ball bearing 2a is installed respectively at the upper and lower side two ends in cylindrical central sleeve 5a, after the radial ball bearing 2a that again central shaft 4a is up passed the lower end from the lower end puts in place, be pressed into the radial ball bearing 2a on top, install correlated parts, the lower end of central shaft 4a is connected with top cylinder seat 7a, and the upper end is the shaft extension end; On the top in the cylindrical central sleeve 5a outside lifter wheel 10a is installed again, installs retainer 3a at the middle part in the outside, in the bottom in the cylindrical central sleeve 5a outside elevating bracket 6a is installed, lifter wheel 10a is fixed on the retainer 3a by pressing plate 9a; At last install transmission gear wheel 1a at the shaft extension end of central shaft 4a, and lock with locking nut.
This complicated structure, two radial ball bearing 2a are difficult at axial locking, owing to the play of radial ball bearing 2a causes circular runout, have a strong impact on the precision of machine, need larger forcing press during assembling radial ball bearing 2a; Elevating bracket 6a need to change according to different types in addition, when changing, must pull down upper driving gear wheel 1a, screw out lifter wheel 10a, whole cylindrical central sleeve conjunction is taken out from retainer 3a, just can again change elevating bracket 6a, the so both useless power of useless worker, and affect original precision.On the other hand, the bottom of cylindrical central sleeve 5a of the prior art is provided with the boss 11a that protrudes from cylindrical central sleeve 5a surface, and this boss 11a and cylindrical central sleeve 5a are an integral body, is used for supporting elevation seat 6a, prevents that elevating bracket 6a from coming off; But this kind structure is in practical work process, and the pressure that boss 11a bears is larger, after boss 11a damages, need to carry out integral replacing to cylindrical central sleeve 5a.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the structure of the cylindrical central sleeve on a kind of circular knitting machine is provided, and simplifies the structure, and has solved the installation hard problem, has improved assembly precision.
The technical scheme that provides according to the utility model, cylindrical central sleeve structure on the described circular knitting machine, comprise cylindrical central sleeve, it is characterized in that: about described cylindrical central sleeve, in the endoporus at two ends taper roll bearing is installed respectively, the outer ring of taper roll bearing is connected with cylindrical central sleeve, mounting center axle in the inner ring of taper roll bearing, the upper end of central shaft are the shaft extension end; Outer upper at described cylindrical central sleeve is installed lifter wheel, outer middle side part at cylindrical central sleeve is installed retainer, in the outer lower portion of cylindrical central sleeve elevating bracket is installed, at the bottom of cylindrical central sleeve fixed tray, at the fixing upper driving gear wheel of the shaft extension end of described central shaft.
Described upper driving gear wheel is fixedly connected with central shaft by the connecting plate of central shaft shaft end.
Described lifter wheel is pressed on the retainer by pressing plate.
The bottom of described central shaft is connected with the top cylinder seat.
Cylindrical central sleeve structure described in the utility model makes to simplify the structure by using two taper roll bearings instead, efficiently solves difficulty is installed, and cost of manufacture is high, has improved assembly precision; The utility model has changed the structure of cylindrical central sleeve, and cylindrical central sleeve and the pallet that is used for the supporting elevation seat are divided into two parts, has reduced the damage of cylindrical central sleeve.
