Abstract
The utility model discloses a taper sleeve disassembly device for a jaw crusher. The taper sleeve disassembly device comprises a jack and a fixing support, wherein the fixing support consists of a base, a disassembly lantern ring and connecting rods which are connected with the base and the disassembly lantern ring; the jack is fixed on the base; the disassembly lantern ring is provided with internal threads which are matched with a taper sleeve; the connecting rods which are connected with the base and the disassembly lantern ring are double-end lead screws; and the base is fixedly connected with the disassembly lantern ring by three to six groups of double-end lead screws. According to the taper sleeve disassembly device for the jaw crusher, the jack and the fixing support are adopted, and the fixing support is fixed by the internal threads which are matched with the taper sleeve on the disassembly lantern ring, so that the taper sleeve disassembly device is simple in integral structure and convenient to use and is suitable for the maintenance and disassembly in various environments and particularly the using environment of the jaw crusher; and by the disassembly device, the taper sleeve of the jaw crusher can be disassembled in a lossless mode.
Description
Technical field
The utility model belongs to mining machinery and manufactures and designs the field, especially belongs to jaw crusher and manufactures and designs the field, the provision for disengagement of particularly a kind of jaw crusher tapered sleeve.
Background technology
Jaw crusher is by four self-aligning roller bearing transmissions.The assembling of bearing is endoporus interference, cylindrical matched in clearance, guarantees the normal operation of machine with this.General jaw crusher bearing seat is equipped with a tapered sleeve, and awl section axle on tapered sleeve and the main shaft and brearing bore all are interference fit.Tapered sleeve is to be used for the jam-pack bearing, guarantees the magnitude of interference and the play of bearing of bearing, and the tapering of tapered sleeve is more convenient, light when guaranteeing that tapered sleeve is dismantled.
In reality, when mistake or damage of bearings occurring, then need dismantle or change bearing like the machine fit on.Because of tapered sleeve be with main shaft and bearing all be interference fit, cause when dismounting, still can not very easily tapered sleeve be pulled down, at this moment generally will adopt forcing press that it is pulled down.Though the method is simple, receives the restriction of condition bigger, just be difficult to it is pulled down or has only bearing is cut like the place of no forcing press, strengthened the maintenance cost of machine so greatly.
Summary of the invention
The utility model discloses the provision for disengagement of a kind of jaw crusher tapered sleeve according to the deficiency of prior art.The problem that the utility model will solve provides a kind of servicing unit, adopts the utility model servicing unit can dismantle the jaw crusher tapered sleeve easily.
The utility model provides following technical scheme to realize:
The provision for disengagement of jaw crusher tapered sleeve comprises jack and fixed support, it is characterized in that: said fixed support is by base, detached collar and be connected base and the connecting rod of detached collar constitutes; Jack is fixed on the base; Said detached collar has the internal thread with the tapered sleeve coupling.
The connecting rod of said connection base and detached collar is the double end leading screw, and base is connected fixing with detached collar through 3 to 6 groups of double end leading screws.
When making up above-mentioned tapered sleeve provision for disengagement: on the inner ring of the detached collar that is drilled with tie rod holes, process internal thread; Detached collar is screwed on tapered sleeve, and the double end leading screw is contained in the tie rod holes of detached collar fixing; The base that will be drilled with through hole then is contained on the double end leading screw, loads onto the nut group, screws; Jack is placed on the seat board, holds out against by main-axis end; Arm bar is injected in the rocking bar hole of jack.Shaking arm bar can pull down tapered sleeve.
There is trapezoidal thread coupling on internal thread and the tapered sleeve to be used for fixing in the above-mentioned detached collar and is connected fixed support and tapered sleeve.The screw thread of the cylindrical on the tooth form of the screw thread on the detached collar, pitch and rotation direction and the tapered sleeve is consistent.
The double end leading screw can be provided with 3 to 6 groups as required, and purpose is that enough intensity dismounting tapered sleeves are arranged.
One round positioning step is arranged on the above-mentioned base.The arm bar effect is to increase arm of force length, reduces very heavy adjusting power.At jack when mounted, expose its rocking bar hole; After guaranteeing that arm bar injects, can easily regulate.
The helpfulness of the utility model is: jack and fixing rack structure are adopted in the provision for disengagement of the utility model jaw crusher tapered sleeve; Fixed support is through fixing with the internal thread of tapered sleeve coupling on the detached collar; Overall structure is simple, and is easy to use, is adapted to various environment; The particularly repair demolition of jaw crusher environment for use adopts the utility model device dismounting disintegrating machine tapered sleeve can realize nondestructive demounting.

The specific embodiment
Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1 to Fig. 4.
The provision for disengagement of jaw crusher tapered sleeve comprises jack 4 and fixed support, and fixed support is made up of base 5, detached collar 2 and the connecting rod 3 that is connected base 5 and detached collar 2; Jack 4 is fixed on the base 5; Detached collar 2 has the internal thread 2b with tapered sleeve 1 coupling.
The connecting rod 3 that connects base 5 and detached collar 2 is double end leading screws, and base 5 is connected fixing with detached collar 2 through 3 to 6 groups of double end leading screws.
As shown in Figure 1, this routine connecting rod 3 adopts 4 groups of connecting rods.As shown in Figure 2, the tie rod holes 2a of even setting is arranged on detached collar 2 ring, the screw thread of the cylindrical on tooth form, pitch and the rotation direction of the internal thread 2b on the detached collar and the tapered sleeve 1 is consistent.
During the provision for disengagement of combination tapered sleeve: on the inner ring of the detached collar that is drilled with tie rod holes 2a 2, process internal thread 2b; Detached collar 2 is screwed on tapered sleeve 1, and the double end leading screw is contained among the tie rod holes 2a of detached collar 2 fixing; The base 5 that will be drilled with through hole then is contained on the double end leading screw, loads onto nut group 6, screws; Jack 4 is placed on the seat board 5, holds out against by main shaft 7 axle heads; Arm bar 8 is injected in the rocking bar hole of jack 4.Shaking arm bar 8 can pull down tapered sleeve 1.
