Description
Technical field
The present invention relates to disintegrating machine, particularly a kind of axial direction positioning device of double-geared roller crusher breaker roll.
Background technology
Double-geared roller crusher is widely used in the mine as the nucleus equipment of mobile crushing station, semi-mobile crushing plant in the glory-hole semi-continuousmining technology system.As shown in Figure 1, the double-geared roller crusher body mainly comprises breaker roll 2 two parts of disintegrating machine box assembly 1, a pair of symmetric arrangement.
When double-geared roller crusher is handled the harder objuct material; Because the randomness of feed, and the cause of spiral cloth tooth have only a pair of or two pairs of teeth are carrying out crushing operation; Breaker roll not only will bear huge radial load; Also to bear huge axial load, and because the uncertainty of hard material position on breaker roll, this axial force is ceaselessly changing direction.Therefore, the axial direction positioning device of breaker roll must have enough intensity, could guarantee reliable, the equipment safety operation in breaker roll location.
At present, the disintegrating machine that use in the mine, the axial location of its breaker roll adopts traditional axle head baffle plate locate mode usually, and the breaker roll structure of prior art is as shown in Figure 2.Breaker roll comprises: roll shaft 11; Be installed in the plurality of teeth ring assemblies 3 at roll shaft 11 middle parts; Be arranged in the some I spacer rings 4 between the said ring gear assembly 3; At the floating end of said roll shaft 11 II spacer ring 5, III spacer ring 6, the floating end bearing block assembly 27 of suit successively, at the stiff end of said roll shaft 11 V spacer ring 24, III spacer ring 6, stiff end bearing block assembly 28, the IV spacer ring 10 of suit successively, and the axial direction positioning device that is installed in said roll shaft 11 both ends.
Said stiff end bearing block assembly 28 by labyrinth Oil sealing assembly 7, outside framework oil seal assembly 18, packing ring 19, bearing 23, thoroughly cover 9 and stiff end bearing block 8 form.
Said floating end bearing block assembly 27 is made up of labyrinth Oil sealing assembly 7, outside framework oil seal assembly 18, bearing 23, end cap 29 and floating end bearing block 25.
The installation of stiff end bearing block assembly:
Successively with labyrinth Oil sealing assembly 7, outside framework oil seal assembly 18, packing ring 19, bearing 23, cover 9 thoroughly and be installed in the stiff end bearing block 8.
The installation of floating end bearing block assembly:
Successively labyrinth Oil sealing assembly 7, outside framework oil seal assembly 18, bearing 23 are installed in the floating end bearing block 25, and end cap 29 and floating end bearing block 25 are fixed in the disintegrating machine box assembly 1 with bolt.
The installation of breaker roll:
Like Fig. 2,3,4,5, shown in 6; At first I spacer ring 4 is arranged on several ring gear assembly 3 both sides; Be installed in roll shaft 11 middle parts successively; Then at the floating end of roll shaft 11 suit II spacer ring 5, III spacer ring 6 successively; Again said floating end bearing block assembly 27 is installed in left end 111 positions of roll shaft 11, then through the screwed hole on the roll shaft 11 110 axle head baffle plate 20 is fixed on the roll shaft 11, with the pre-fastening moment of bolt 21 pretensions to regulation with bolt 21, packing ring 22; Bolt 21 is pressed in the end face of III spacer ring 6 on the shaft shoulder 113 of roll shaft 11 through axle head baffle plate 20, bearing 23 inner rings, and the shaft shoulder 113 of the end face of III spacer ring 6 and roll shaft 11 will be as the positioning reference of the associated component on the roll shaft 11 (ring ring gear assembly 3, I spacer ring 4, II spacer ring 5, III spacer ring 6, V spacer ring 24 etc.) on roll shaft 11 like this; Then at the stiff end of roll shaft 11 suit V spacer ring 24, III spacer ring 6 successively; Said stiff end bearing block assembly 28 is installed in right-hand member 112 positions of roll shaft 11; Again with IV spacer ring 10, shaft coupling 26 roll shaft 11 right-hand members of packing into successively; And through the screwed hole on the roll shaft 11 110 axle head baffle plate 20 is fixed on the roll shaft 11 with bolt 21, packing ring 22; With the pre-fastening moment of bolt 21 pretensions to regulation, bolt 21 is pressed in the end face of III spacer ring 6 on the end face of V spacer ring 24 through axle head baffle plate 20, shaft coupling 26, IV spacer ring 10, bearing 23 inner rings.
Like this; The axle head baffle plate assembly at roll shaft 11 two ends (bolt 21, packing ring 22, axle head baffle plate 20) is fixed on the associated component on the roll shaft 11 (ring ring gear assembly 3, I spacer ring 4, II spacer ring 5, III spacer ring 6, V spacer ring 24 etc.) on bearing 23 inner rings of roll shaft 11 stiff ends.Stiff end bearing block 8 stops bearings 23 outer rings to be gone here and there left through the shaft shoulder 80, packing ring 19, and stiff end bearing block 8 and cover 9 thoroughly and be connected in the disintegrating machine casing 1 through bolt 16, packing ring 17 covers 9 end face 90 thoroughly and can stop bearing 23 outer rings to be gone here and there to the right.
After the installation, associated component on the roll shaft 11 (ring ring gear assembly 3, I spacer ring 4, II spacer ring 5, III spacer ring 6, V spacer ring 24 etc.) is in the position on the roll shaft 11 and the position of breaker roll 2 in the disintegrating machine casing is all unique confirms.
There is following defective in the axial direction positioning device of the breaker roll of prior art:
A) like Fig. 5,6, shown in 7; Owing to the restriction of axle head size, can only adopt the axle head baffle plate fastening bolt 21 of negligible amounts, be the reliability that guarantees the location; Must strengthen the specification of axle head baffle plate fastening bolt 21; The big more pretightning force of bolt is big more, and the hydraulic spanner specification of employing is also big more, and pretension is more difficult;
B) like Fig. 5, shown in 6; In order to reach the purpose of associated component on the locking roll shaft 11, must leave gap H between axle head baffle plate and the axle head, strain will inevitably take place in baffle plate 20 during bolt 21 pretensions; The pretension that is unfavorable for bolt, bolt 21 is as easy as rolling off a log loosening under impact loading;
C) the axle head baffle plate 20 of drive end is installed in the shaft coupling 26, in case occur looseningly being not easy to find early, and must take said shaft coupling 26, maintenance difficult apart during maintenance in the use.
Obviously, the traditional breaker roll axial direction positioning device unusual shortcoming of inconvenience, operational reliability difference of installation, maintaining that has equipment.
Summary of the invention
