Background technique
As Fig. 4, shown in Figure 5, in the rubber membrane sealed type gas cabinet, levelling device mainly is made up of members such as leveling counterweight 91, weight guide 92, cabinet top upper saw pulley 93, wire rope 94 and leveling pulleys 95.Wherein every set of weights connects two wire rope, links to each other with the piston (not shown) with cabinet top upper saw pulley 93 by cabinet top leveling pulley 95.As shown in Figure 3, two upper saw pulleys 93 that equidistantly distribute along the wire rope vertical line are arranged on every wire rope 94, this upper saw pulley 93 is positioned on the arch form cabinet top, is fixedly connected on the arch form cabinet top by fixed support 96, mainly wire rope is played support and guide-localization effect.As shown in Figure 5, existing upper saw pulley 93 is made up of bearing support 931, axle 932, pulley 933 and Cock screw 934 etc., and what its bearing support 931 adopted is that integral body has the positive sliding bearing of lining, and promptly the outside is a bearing support housing 9311, liner axle sleeve 9312, axle sleeve 9312 is connected with axle 932.The problem that should existing wheel design exists is, the wire rope 94 that is in operation inevitably can deflect, and the transverse force that 94 pairs of pulleys of wire rope 933 produce makes pulley 933 drive axle 932 lateral shift takes place together that the time has been grown and can scurry a phenomenon.In addition, in installation process, the installation that is in two upper saw pulleys 93 on the same wire rope aligns very difficulty, inevitably there is installation deviation to a certain extent, 94 pairs of pulleys of wire rope 933 produce the eccentric force effect, cause the frictional force between wire rope 94 and the upper saw pulley 93 to strengthen, accelerate the wearing and tearing of wire rope 94 or upper saw pulley 93, influence its working life.
In view of this, the inventor relies on relevant design and manufacturing experience for many years, proposes the upper saw pulley of a kind of installation convenience, the better gas cabinet levelling device of using effect, to overcome the defective of prior art.
The model utility content
The purpose of this utility model is to provide a kind of upper saw pulley of rubber membrane sealed type gas cabinet levelling device, and band plummer block housing roller bearing units that this upper saw pulley adopts and shaft axis allow the certain angle of deflection, the convenient installation, and can avoid producing eccentric force; Between the bearing of axle and two bearing supports, be provided with adapter sleeve, with prevent effectively the axle about scurry out.
The purpose of this utility model is to realize like this, a kind of upper saw pulley of rubber membrane sealed type gas cabinet levelling device, described upper saw pulley is fixedly connected on the arch form cabinet top by fixed support, this upper saw pulley includes axle and is fixed on a pulley of a last intermediate portion, and the axle two ends are connected on the bearing support by bearing; The diaxon bearing is fixedly installed on the described support; Described bearing is band conical bore single-row centripetal outer spherical surface deep groove ball bearing, the inner ring of described bearing is connected with axle by a taper tightly fixed liner, the big end of described taper tightly fixed liner is towards the direction of described pulley, and the small end of described taper tightly fixed liner is provided with lock washer and the locking nut of locking on the taper tightly fixed liner.
In a better embodiment of the present utility model, described bearing support is the casting plummer block housing.
In a better embodiment of the present utility model, described pulley is fixed on the described axle by Cock screw.
In a better embodiment of the present utility model, described bearing support is provided with lubricating cup.
The band plummer block housing outer spherical surface deep groove ball bearing that upper saw pulley of the present utility model adopts can restrictive axes bi-directional axial move in the play scope of bearing.Roller bearing units and shaft axis allow certain deflection because this is usherd to seat, and help the work that aligns that cabinet pushes up two upper saw pulleys on the same wire rope in the installation process, the convenient installation.When normal operation, when wire rope deflects, two pulleys can be aligned automatically by single-row centripetal outer spherical surface deep groove ball bearing, can avoid the generation of eccentric force; In addition, be provided with taper tightly fixed liner, lock washer and locking nut at bearing inner race, can prevent effectively the axle about scurry out.Simultaneously, upper saw pulley of the present utility model, simple in structure, construction install convenience helps promoting the use of.
