Abstract
The utility model relates to a main shaft assembly used for a vacuum extruder, which is composed of a main shaft, a double-row aligning bearing set, a thrust bearing set, and a front end sealing element and a back end sealing element of the main shaft which are arranged in a bearing seat. The main shaft assembly is arranged in an inner cavity of a machine seat, and the utility model has the advantages of convenient assembly and disassembly, and convenient maintenance. The front end of the main shaft is provided with a pressure spring type automatic compensating sealing device which can automatically regulate the closed degree of the automatic compensating sealing device and the main shaft, and the vacuum degree of vacuum chambers is ensured.
Description
The utility model relates to the main shaft of extruding of de-airing extruder, promptly a kind of main shaft assembly.
The subordinate that existing vacuum is squeezed in mud (brick) machine extrudes main shaft and radial bearing, thrust bearing and seal are contained in the support of extruder one by one, relatively more difficult and heavy to demolition, maintenance, one or both ends at main shaft are provided with seal, because it is contained in the support inner chamber, can't adjust after the forward end seal wearing and tearing gas leakage,, not only influence the performance of loom in case lose sealing, product quality is descended, simultaneously, making vacuum chamber is negative pressure, and the lubricating grease of bearing bore is blotted, quicken bearing wear, change bearing or main shaft and have only whole disassembles, when taking a lot of work, inconvenience.
The utility model influences the loom serviceability and tears the difficult technical barrier of driving replacing open in order to solve the mounting structure defective of above-mentioned de-airing extruder main shaft, provides assembling simple and convenient, a kind of main shaft assembly of sealing before adjusting automatically.
Realize purpose of design of the present utility model, intend by the following technical solutions: the structure of main shaft assembly is by main shaft, the double-row self-aligning roller bearing group, garden awl roller thrust block group, seal and bearing block are formed, the middle part that is characterized in main shaft is one group of double-row self-aligning bearing group and one group of garden awl roller thrust block group in proper order, front-end of spindle compressed spring type automatic compensation sealing device, back-end sealing spare, they and spindle mounted are in the bearing block of a transition, constitute main shaft assembly, this main shaft assembly is packed in the main frame support.The compressed spring type automatic compensation sealing device of front-end of spindle setting has seal receptacle, seal, and hold-down ring, stage clip, pressure-regulating sleeve, hold-down ring, stage clip are assemblied between seal and the pressure regulation swivel nut.
Good effect of the present utility model is: by the bearing in the mud extruder support of originally packing into one by one, seal and main shaft change in the bearing block that all is contained in a transition, connect housing by bolting, are convenient to assembling, tear open and drive maintenance; The compressed spring type automatic compensation sealing device that front-end of spindle is provided with can be adjusted the driving fit Cheng Du with main shaft automatically, reduces maintenance, keeps the vacuum in the loom vacuum chamber, helps guaranteeing product quality.
Below, according to accompanying drawing, in conjunction with the embodiments, details are as follows to technology contents of the present utility model:
Fig. 1 is the utility model topology view.
The utility model main shaft assembly structure as shown in Figure 1, main shaft 12 is assemblied in the bearing block 8, and guarantees main axis rotation and radial positions by one group of double-row self-aligning bearing 7, the opposite force of mud, the supporting that keeps axial location are squeezed in one group of thrust axis 9 opposing.The rear end of main shaft 12 has sealed packing 10 to seal, front end is provided with compressed spring type automatic compensation sealing device, the sealed packing 2 of this device, hold-down ring 3, stage clip 4 and pressure regulation swivel nut 5 are arranged in order and are assemblied in seal receptacle 6, sealed packing 2 is with the passing of service time, wearing and tearing gradually, elastic force with pressured spring 4 pushes many sealed packings 2 forward, and automatic connection ground compensates the wearing and tearing of sealed packing 2, adjusts the adaptation with main shaft 12 automatically, prevent gas leakage, guarantee the vacuum of complete machine vacuum chamber, the whole main shaft assembly support inner chamber of packing into is by the fixedly connected casing 11 of bearing block 8 usefulness hex bolts.When pug is clamp-oned vacuum chamber by higher level's auger, by the main shaft 12 drive master of the subordinate flood dragons 1 extruding outlet of rotation, moulded blank.
Claims (2)
1, a kind of main shaft assembly, it is by main shaft, double-row self-aligning roller bearing group, garden taper roller bearing group, main shaft seal spare and bearing block are formed, the middle part that it is characterized in that main shaft is one group of double-row self-aligning bearing (7) and one group of garden taper roller bearing (9) in proper order, main shaft (12) front end is a compressed spring type automatic compensation sealing device, and back-end sealing spare (10) and main shaft (12) are assemblied in the bearing block (8) of a transition, in the support of packing into.
2, by the described a kind of main shaft assembly of claim 1, it is characterized in that the sealed packing (2) of front-end of spindle compressed spring type automatic compensation sealing device, hold-down ring (3), stage clip (4), pressure regulation swivel nut (5) are arranged in order and are fitted to seal receptacle (6).
