Model utility content
For the deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of cost pulley assembly lower, easy to maintenance.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is a kind of crusher axis pulley assembly of design: comprise main shaft 2 and belt pulley 3;
The axis hole of A, described belt pulley 3 is with ladder more than one-level, and the end of described main shaft 2 is installed in the ladder axis hole of belt pulley 3;
B, between the end of described main shaft 2 and the main step 10 of the ladder axis hole of belt pulley 3, also swelling device is installed.
Described swelling device is made up of expansion sleeve 5, inner expension cap 4, outer expansion set 7 and more than one swelling screw 6; The endoporus two ends of described expansion sleeve 5 are little horn-like of outer imperial palace, its jacket wall have axially open 12; Described inner expension cap 4 is the frustums with reverse taper holes, and Qi Bishang has the screw 14 supporting with swelling screw 6; Described outer expansion set 7 is also the frustum with reverse taper holes, and Qi Bishang has the through hole 13 supporting with swelling screw 6; Inner expension cap 4 and outer expansion set 7 are arranged in the bellmouth orifice at expansion sleeve 5 two ends respectively, are connected by swelling screw 6.
In the end of described main shaft 2, hubcap 9 is also installed, and by head bolts 8, the end of hubcap 9 with belt pulley 3 is connected as a single entity.
Also be provided with auxiliary step 11 in main step 10 front end of described belt pulley 3 ladder axis hole, the edge of described main shaft end cap 9 is pressed on the edge of this auxiliary step 11.
Crusher axis pulley assembly of the present utility model, eliminate the parts such as existing flange, connecting key, and the through hole eliminated on belt pulley and dismounting screw, and change the axis hole of belt pulley into ladder hole by taper hole, thus, difficulty of processing and the amount of finish of belt pulley and main shaft is greatly reduced, simultaneously, adopt size swelling device that is less, easy processing to substitute, therefore its cost is lower.In addition, during installation and removal, only the swelling screw in swelling device need be screwed or unscrews, thus, the dismounting of belt pulley is more convenient, so save dismounting time, alleviate labor intensity.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.Explanation below adopts the mode exemplified, but protection domain of the present utility model should not be limited to this.
The present embodiment is made up of main shaft 2, belt pulley 3, swelling device and hubcap 9.
The end of main shaft 2 is cylindrical, and its end face has more than one screw, for installing head bolts 8.
The axis hole of belt pulley 3 is secondary ladder hole, and the ladder of its inside is main step 10, and the ladder of its outside is auxiliary step 11.
Swelling device is made up of expansion sleeve 5, inner expension cap 4, outer expansion set 7 and more than one swelling screw 6 (this example adopts six).
The endoporus two ends of expansion sleeve 5 are outer imperial palace little horn-like (that is: bellmouth orifice), and the length of its bellmouth orifice is close to the inner portion less than the length of the bellmouth orifice in outer portion; On the jacket wall of expansion sleeve 5, also have axially open 12 (for expansion sleeve 5 distending and contraction).
Inner expension cap 4 is centre frustums with reverse taper holes, and Qi Bishang has the screw 14 supporting with swelling screw 6.
Outer expansion set 7 is also the frustum of a centre with reverse taper holes, and Qi Bishang has the through hole 13 supporting with swelling screw 6.
During installation, first mainshaft bushing 1 is installed on main shaft 2, again belt pulley 3 is threaded onto the end of main shaft 2, then, inner expension cap 4 is threaded onto on main shaft 2, and be placed in main step 10 position of belt pulley 3 inner step, then, expansion sleeve 5 and outer expansion set 7 being installed successively is installed on main shaft 2, again by swelling screw 6 through the through hole 13 on outer expansion set 7 wall and in the screw 14 of spinning on inner expension cap 4 wall, by screwing swelling screw 6, inner expension cap 4 is drawn in the bellmouth orifice of expansion sleeve 5 inside end, simultaneously, outer expansion set 7 is clamp-oned in the bellmouth orifice of expansion sleeve 5 outer end, make expansion sleeve 5 distending, and then make the outer cylinder of expansion sleeve 5 tightly prop up the wall surface of the hole at belt pulley 3 axis hole main step 10 position, thus belt pulley 3 and main shaft 2 are connected as a single entity.Thereafter, hubcap 9 is pressed on the edge of the auxiliary step 11 of belt pulley 3 ladder axis hole, with head bolts 8, the end face of hubcap 9 with main shaft 2 is connected.
During dismounting, contrary with above-mentioned steps.
Crusher axis pulley assembly of the present utility model, can use with impacting vertical crusher or other various disintegrator or other machinery support.
