Description
Technical field
The utility model relates to a kind of compression roller of granulator, particularly relates to a kind of non-maintaining pressure roller, belongs to grain feed working machine technical field.
Background technique
Existing compression roller of granulator work under bad environment, roller bearing works under high temperature, dust atmosphere, needs the mode by frequently increasing lubricating grease; meet bearing lubrication needs; and the material entering bearing bore is released, clean to maintain bearing bore, avoid bearing by dust erosion.Under this working method, lubricating grease waste is serious, and the waste and old grease contaminated feed got rid of.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, providing a kind of in process of production without the need to adding the non-maintaining pressure roller of oiling agent, avoiding waste and old grease contaminated feed.
For achieving the above object, the technological scheme that the non-maintaining pressure roller of the utility model adopts is:
A kind of non-maintaining pressure roller, comprise roll shaft, roller shell and bearing, bearing housing is connected on the outside of roll shaft, roller valve jacket is connected on the outside of bearing, seal arrangement for sealed roller shell and roller clearance is installed in the both sides of bearing, at least the seal arrangement of side is labyrinth gland, and this labyrinth gland comprises the rotary packing ring be connected with roller shell and the stationary seal ring be connected with roll shaft, and rotary packing ring and stationary seal ring are provided with mutual concavo-convex chimeric labyrinth structure.Rotary packing ring is followed roller shell and is rotated, stationary seal ring is fixedly connected with roll shaft, the concavo-convex chimeric labyrinth structure of dynamic and static seal ring can avoid extraneous particulate dust to enter bearing bore, also inner lubricating grease can be avoided to spill into pressure roller outside simultaneously, in use do not need to add oiling agent, reduce cost of production, it also avoid waste and old grease contaminated feed.
The seal arrangement of bearing both sides is labyrinth gland.Both sides all adopt labyrinth gland better can not spill into outside by packing grease, ensure that lubricating grease remains in bearing bore and lubricate.
Stationary seal ring comprises the first toroidal surface, first toroidal surface is wholely set the axle sleeve be tightly connected with roll shaft, the outer ring of the first toroidal surface is provided with first protruding and the second projection, the first scrobicular ring is formed between first projection and the second projection, rotary packing ring comprises the second toroidal surface, the inner ring surface of the second toroidal surface coordinates with axle sleeve, and the second toroidal surface is provided with the 3rd projection, and the 3rd projection is entrenched in the first scrobicular ring.Axle sleeve adds the sealing surface of stationary seal ring and roll shaft, improves sealing effect, projection and the scrobicular ring chimeric resistance adding grease and overflow mutually; The setting of the first toroidal surface, the second toroidal surface adds stationary seal ring and coordinates with the radial area of rotary packing ring, improves sealing effect.
The second described toroidal surface is wholely set the sliding sleeve be slidably matched with axle sleeve.Sliding sleeve adds the sealing area between rotary packing ring and stationary seal ring, improves sealing effect.
Sliding sleeve is socketed with seal ring, and sealing circle is for sealing the gap between the first toroidal surface and the second toroidal surface.Installing seal ring near the position of roll shaft, first is locked gap between stationary seal ring and rotary packing ring, effectively raise sealing effect.
Described seal ring is V-shaped seal ring.
Rotary packing ring is connected with roller shell by screw.
Stationary seal ring realizes circumference by key and roll shaft and locates, and realizes axially locating by the step of roll shaft or nut.
The utility model compared with prior art, has the following advantages:
Rotary packing ring is followed roller shell and is rotated, stationary seal ring is fixedly connected with roll shaft, the concavo-convex chimeric labyrinth structure of dynamic and static seal ring can avoid extraneous particulate dust to enter bearing bore, and cast most of material aside sealing area, also inner lubricating grease can be avoided to spill into pressure roller outside simultaneously, be in use do not need to add oiling agent, reduce cost of production, it also avoid waste and old grease contaminated feed.
Accompanying drawing explanation
Fig. 1 is non-maintaining roller structure schematic diagram.
Fig. 2 is the enlarged view at A place in Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these mode of executions should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As illustrated in fig. 1 and 2, non-maintaining pressure roller comprises roll shaft 1, roller shell 2 and circular cone roller bearing 3, roller shell 2 is by one group of circular cone roller bearing 3, be installed on roll shaft 1, during work, roller shell 2 rotates around roll shaft 1, bearing bore two ends are provided with labyrinth gland 4, this labyrinth gland 4 is by V-seal part 5, rotary packing ring 6 and stationary seal ring composition, rotary packing ring 6 is connected with roller shell 2 by bolt, stationary seal ring realizes circumference by key 8 and roll shaft and locates, axially locating is realized by the step 11 of roll shaft or nut 12, when roller shell 2 rotates, rotary packing ring 6 rotates with roller shell 2, stationary seal ring 7 keeps state of rest, rotary packing ring 6 and stationary seal ring 7 form complete labyrinth seal mechanism.Stationary seal ring comprises outer ring that the first toroidal surface 71, first toroidal surface is wholely set axle sleeve 72, first toroidal surface 71 be tightly connected with roll shaft 1 and is provided with between the first protruding 73 and second projection 74, first protruding 73 and the second projection 74 and forms the first scrobicular ring 75.Rotary packing ring 6 comprises the second toroidal surface 61, second toroidal surface and is wholely set sliding sleeve 62, second toroidal surface be slidably matched with axle sleeve 72 and is provided with the 3rd projection the 63, three projection 63 and is entrenched in the first scrobicular ring 75.Sliding sleeve is socketed with V-shaped seal ring, and this V-shaped seal ring is for sealing the gap between the first toroidal surface 71 and the second toroidal surface 61.
