Abstract
The utility model discloses a sealing connecting structure between a tub body and a spindle of a washing and dewatering machine. The sealing connecting structure comprises a sealing body, the spindle is sleeved with the sealing body, one end of the sealing body is connected to a bearing block, close to the tub body, on the spindle, a sealing cavity is formed between the sealing body and the spindle, sealing stuffing is arranged in the sealing cavity, the sealing body is sleeved with a sealing ring, and a stopping and pushing device is arranged on the sealing body and can push the sealing ring to move on the sealing body towards one side of the tub body until the sealing ring is stopped on and abuts against the tub body in a sealing mode. The sealing connecting structure has the advantages that it can be effectively guaranteed that the sealing body and the spindle are coaxial, and the service life of the whole sealing device is greatly prolonged; in addition, the sealing connecting structure is convenient to demount and maintain.
Description
Technical field
The utility model relates to the Hermetical connecting structure between staving and the main shaft of cleaning/squeezing machine cleaning-drum.
Background technique
Washer-extractor is called for short cleaning/squeezing machine.Cleaning/squeezing machine is widely used in hospital, school, hotels and other places.At present, Hermetical connecting structure between staving and the main shaft of cleaning/squeezing machine cleaning-drum is: seal one end and staving rear wall welded seal are fixed, the other end of seal is connected on the bearing support of close staving one side of main shaft, between seal and main shaft, form seal chamber, in seal chamber, be provided with stuffing box packing.The shortcoming of above-mentioned Hermetical connecting structure is: on the one hand, seal and staving fixedly mount the alignment error of bringing and be difficult to guarantee seal and main shaft concentric, once seal axle center different from main shaft, whole seal arrangement easily damages; On the other hand, seal is fixedly connected with staving, makes the field-strip of bearing support on main shaft and whole seal arrangement all very inconvenient.
Model utility content
The purpose of this utility model is: provide a kind of simple in structure, can effectively guarantee the concentric and field-strip of seal and the main shaft Hermetical connecting structure between cleaning/squeezing machine staving and main shaft easily.
For achieving the above object, the technical solution adopted in the utility model is: the Hermetical connecting structure between cleaning/squeezing machine staving and main shaft, comprise: be sleeved on the seal on main shaft, seal one end is connected on main shaft near on the bearing support of staving, between seal and main shaft, form seal chamber, in seal chamber, be provided with stuffing box packing, on seal, be set with seal ring, on seal, be also provided with gear and push away device, gear push away device can promote seal ring on seal to staving one side shifting, until seal ring sealing gear is leaned against on staving.
Further, Hermetical connecting structure between aforesaid cleaning/squeezing machine staving and main shaft, wherein, the structure that described gear pushes away device comprises: back-up ring, back-up ring is made up of body and baffle plate, on body madial wall, is provided with screw thread, and body is arranged on seal by screw-thread fit, the body of back-up ring is arranged on the bottom of seal ring away from staving one side, and baffle plate gear leans against the end of seal ring away from staving one side.
Further, the Hermetical connecting structure between aforesaid cleaning/squeezing machine staving and main shaft, wherein, on seal ring, buckle has anchor ear.
The utility model has the advantages that: can effectively guarantee seal and main shaft concentric, thereby greatly extend the working life of whole seal arrangement; In addition, dismounting and maintenance are all very convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Hermetical connecting structure between cleaning/squeezing machine staving described in the utility model and main shaft.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As shown in Figure 1, Hermetical connecting structure between cleaning/squeezing machine staving and main shaft, comprise: be sleeved on the seal 2 on main shaft 1, one end of seal 2 is fixedly mounted on main shaft 1 near on the bearing support 3 of staving 6, between seal 2 and main shaft 1, form seal chamber, in seal chamber, be provided with stuffing box packing 4, on seal 2, be set with seal ring 5, on seal 2, be also provided with gear and push away device, gear push away device can promote seal ring 5 on seal 2 to staving 6 one side shiftings, until seal ring 5 sealing gear is leaned against on staving 6.In the present embodiment, the structure that gear pushes away device comprises: back-up ring, back-up ring is made up of body 71 and baffle plate 72, on body 71 madial walls, be provided with screw thread, body 71 is arranged on seal 2 by screw-thread fit, the body 71 of back-up ring is arranged on the bottom of seal ring 5 away from staving 6 one sides, and baffle plate 72 gears lean against the end away from staving 6 one sides of seal ring 5.In addition,, in order to guarantee better the sealing effect of seal ring 5, on seal ring 5, buckle has anchor ear 8.
The utility model has the advantage of: by being screwed into back-up ring to staving 6 one sides, make seal ring 5 on seal 2 to staving 6 one side shiftings, until seal ring 5 sealing gear leans against on staving 6.The mode that is tightly connected so has effectively guaranteed seal 2 and main shaft 1 concentric, thereby has greatly extended the working life of whole seal arrangement.In addition, in dismounting bearing support 3, seal 2 can be disassembled in the lump, make the dismounting of bearing support 3 and seal 2 and maintenance all very convenient.
