Description
Technical field
The utility model is related to roll squeezers more particularly to one kind can no-welding roll squeezer alloy roller set.
Background technology
Roll squeezer is a kind of cement energy-saving milling equipment, has and substitutes high energy consumption, efficiency low ball grinding machine pregrinding system, and
And the function of steel consumption and noise is reduced, workflow is to feed material above two rollers, is squeezed pressure roller continuous band and enters
Between roller, after the high pressure effect of 100-150MPa, become to be discharged under closely knit material cake slave, the material cake of discharge.Roll squeezer is equal
Be by shaft mounted roller set realize it is replaceable, roller set will appear abrasion during use, at this stage be usually lead to
It crosses welding to fix itself and shaft, when being replaced, replacement is not easy.
Utility model content
The purpose of this utility model be that provide one kind to solve the above-mentioned problems can no-welding roll squeezer alloy roller
Set.
The utility model is achieved through the following technical solutions above-mentioned purpose：
One kind can no-welding roll squeezer alloy roller set, including roller jacket layer and roller cover tooth, and the roller jacket layer is sleeved on the roller
In the shaft of press, the roller set tooth is fixedly mounted on the roller jacket layer；
The medial surface of the roller jacket layer is provided with stepped tooth, and the lateral surface of the shaft is provided with to be adapted to the stepped tooth
Dovetail groove；
The lateral surface of the roller jacket layer is provided with mounting groove, and the roller set tooth is mounted in the mounting groove；
The coefficient of thermal expansion of the shaft, the coefficient of thermal expansion of the roller jacket layer and the roller set tooth coefficient of thermal expansion according to
Secondary diminution.
Specifically, multiple mounting grooves are uniformly distributed along the lateral surface of the roller jacket layer, the mounting groove and the roller
The axis parallel of jacket layer.
Further, the middle part of multiple mounting grooves is welded with lattice block, and the length of the roller set tooth is kept off with the lattice
The distance at block to the both ends of the roller jacket layer is equal.
Specifically, the mounting groove is trapezium structure, and the bottom width of the mounting groove is more than the top surface of the mounting groove
Width, the roller set tooth is trapezium structure, and the bottom width of the roller set tooth is more than the top surface width of roller set tooth, the roller
The height for covering tooth is more than the depth of the mounting groove.
The beneficial effects of the utility model are：
The utility model can no-welding roll squeezer alloy roller set cover tooth by the way that roller set is divided into detachable roller jacket layer and roller,
And connect it with shaft by being interference fitted, avoid the mode using welding from connecting, while in the process of work, when roller set
When tooth is worn, tooth can be covered with roller, the roller set tooth of damage is replaced, contribute to the service life for extending roller set.
Description of the drawings
Fig. 1 be it is described in the utility model can no-welding roll squeezer alloy roller set sectional view；
Fig. 2 be it is described in the utility model can no-welding roll squeezer alloy roller set side view.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the utility model one kind can no-welding roll squeezer alloy roller set, including roller jacket layer 2 and roller set
Tooth 4, roller jacket layer 2 are sleeved in the shaft 1 of roll squeezer, and roller set tooth 4 is fixedly mounted on roller jacket layer 2；The medial surface of roller jacket layer 2 is set
It is equipped with stepped tooth 4, the lateral surface of shaft 1 is provided with the dovetail groove being adapted to stepped tooth 4；The lateral surface of roller jacket layer 2 is provided with peace
Tankage, roller cover tooth 4 and are mounted in mounting groove；The heat of the coefficient of thermal expansion of shaft 1, the coefficient of thermal expansion of roller jacket layer 2 and roller set tooth 4
The coefficient of expansion reduces successively, and multiple mounting grooves are uniformly distributed along the lateral surface of roller jacket layer 2, the central axes of mounting groove and roller jacket layer 2
Parallel, the middle parts of multiple mounting grooves is welded with lattice block, roller cover the length dative block of tooth 4 to the both ends of roller jacket layer 2 away from
From equal, mounting groove is trapezium structure, and the bottom width of mounting groove is more than the top surface width of mounting groove, and it is trapezoidal knot that roller, which covers tooth 4,
Structure, the bottom width that roller covers tooth 4 are more than the top surface width that roller covers tooth 4, and roller covers depth of the height more than mounting groove of tooth 4.
The utility model it is a kind of can no-welding roll squeezer alloy roller set operation principle it is as follows：
When mounted, countershaft 1 cools down, and 1 shrinkage of shaft, two pairs of rollers jacket layer 2 is made to heat up, and makes 2 heat expansion of roller jacket layer,
Then roller jacket layer 2 is installed to shaft 1, and restored to room temperature, after the normal size for restoring shaft 1 and roller jacket layer 2, realized and turn
The interference fit of axis 1 and roller jacket layer 2；Then two pairs of rollers jacket layer 2 carries out heating heat expansion, and two pairs of rollers set tooth 4 carries out cooling shrinkage, by roller set
In the installation to mounting groove of tooth 4, and restore to room temperature, realizes interference fit.
When needing two pairs of rollers set tooth 4 to be replaced, roller set tooth 4 is split out out of mounting groove by nail hammer, according to above-mentioned side
Method installs new roller set tooth 4.
Because the coefficient of thermal expansion of the coefficient of thermal expansion of shaft 1, the coefficient of thermal expansion of roller jacket layer 2 and roller set tooth 4 contracts successively
It is small, therefore at work, the whole fever of roller set can further increase the connective stability between all parts, avoid in work
The case where sliding in the process.
The technical solution of the utility model is not limited to the limitation of above-mentioned specific embodiment, every skill according to the present utility model
The technology deformation that art scheme is made, each falls within the scope of protection of the utility model.
