Abstract
The utility model discloses a hydraulic thrust roller of a rotary kiln. The hydraulic thrust roller of the rotary kiln is characterized in that a thrust roller, a thrust roller shaft and a thrust roller base are included, the thrust roller base is provided with a through hole, the thrust roller is mounted on the thrust roller shaft, the thrust roller shaft is rotatably arranged on the thrust roller base through first bearings, the first bearings are arranged in the through hole, a step which protrudes out of the inner wall of the through hole is arranged in the through hole, the first bearings are arranged above the step, a second bearing is mounted on the thrust roller shaft, the second bearing is arranged in the through hole and placed below the step, the step stops the first bearings from moving downwards, and the step stops the second bearing from moving upwards. According to the hydraulic thrust roller of the rotary kiln, the step is arranged in the through hole of the thrust roller base, the first bearings, the thrust roller shaft and the thrust roller can be made to be subjected to both downward axial force and upward axial force, the structure is stable, using is safe, and accident risks are small.
Description
Technical field
The utility model relates to a kind of hydraulic blocking wheel of rotary kiln.
Background technology
During hydraulic blocking wheel work, rotary kiln body moves back and forth along kiln centerline direction by certain speed and stroke on support roller, makes to take turns the energy uniform wear in overall with of band and support roller and large pinion, avoids grinding groove, with the service life of extension device.Wherein a hydraulic blocking wheel, utilizes bearings gear wheel axle.Gear wheel is arranged on bearing top.Bearing is arranged in cavity volume from the upper shed direction of gear wheel seat.When gear wheel and gear wheel bearing are subject to downward pressure, bearing can be shared its pressure, and owing to being subject to downward restriction, gear wheel, gear wheel axle and bearing all can not offset downward.But when reality is used, gear wheel and gear wheel axle likely can be subject to axial force upwards.Owing to there is no limiting structure, the axial force making progress can make gear wheel disequilibrium, makes gear wheel and the upper and lower play of gear wheel axle and beat; When serious, can make it in gear wheel seat, rout up, cause serious accident.
Utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of hydraulic blocking wheel of constitutionally stable rotary kiln is provided.
For realizing above object, the utility model is achieved through the following technical solutions:
The hydraulic blocking wheel of rotary kiln, is characterized in that, comprises gear wheel, gear wheel axle and gear wheel seat; Described gear wheel seat is provided with through hole; Described gear wheel is installed on gear wheel axle; Described gear wheel axle is arranged on gear wheel seat rotationally by clutch shaft bearing; Described clutch shaft bearing is arranged in through hole; In described through hole, be provided with the step that protrudes from through-hole wall; Described clutch shaft bearing is arranged at step top; On described gear wheel axle, the second bearing is installed, described the second bearing is arranged in described through hole and is positioned at described step below; Described step stops that described clutch shaft bearing moves down, and described step stops that the second bearing moves up.
Preferably, described clutch shaft bearing number is three, is arranged above and below.
Preferably, on described gear wheel axle, be provided with baffle plate, described the second bearing is between described baffle plate and described step.
Preferably, on described gear wheel seat, be provided with cover plate, described cover plate seals described through hole lower end.
Preferably, described gear wheel seat is provided with sleeve; Shown in sleeve set on guide post, and can slide along guide post; Described guide post is arranged on base.
Preferably, also comprise hydraulic cylinder, the piston rod of hydraulic cylinder drives gear wheel seat to move.
The hydraulic blocking wheel of the rotary kiln in the utility model, in the through hole of gear wheel seat, step is set, both can make clutch shaft bearing, gear wheel axle and gear wheel bear downward axial force, can make again it bear axial force upwards, no matter bear the axial force of which direction, all can not make gear wheel axle and gear wheel skew and swing Stability Analysis of Structures, use safety, the risk causing the accident is little.
Accompanying drawing explanation
Fig. 1 is that the utility model is faced and partly cutd open figure, axially partly cuts open figure.
Fig. 2 is that the utility model is overlooked part and partly cutd open figure.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1 and Figure 2, the hydraulic blocking wheel of rotary kiln, comprises gear wheel 1, gear wheel axle 2 and gear wheel seat 6.Gear wheel seat 6 is provided with through hole 7.In through hole 7, be provided with the step 71 that protrudes from through hole 7 inwalls.Gear wheel 1 is installed on gear wheel axle 2.Gear wheel axle 2 is arranged on gear wheel seat 6 rotationally by three clutch shaft bearings 3.Three clutch shaft bearings 3 are arranged in through hole 7, are arranged above and below, and are arranged at step 71 tops.The second bearing 4, the second bearings 4 are installed on gear wheel axle 2 to be arranged in through hole 7 and to be positioned at step 71 belows.Step 71 both can stop that clutch shaft bearing 3 moved down, and also can stop that the second bearing 4 moves up.On gear wheel axle 2, be provided with baffle plate 9, the second bearings 4 between baffle plate 9 and step 71.On gear wheel seat 6, be provided with cover plate 8, cover plate 8 seals through hole 7 lower ends.
Gear wheel seat 6 is provided with sleeve 9, and sleeve 9 is sleeved on guide post 10, and can slide along guide post 10.Guide post 10 is arranged on base 11.Gear wheel seat 6 one sides are provided with hydraulic cylinder 12, and the piston rod 13 of hydraulic cylinder 12 drives gear wheel seat 6 to move.
Embodiment in the utility model, only for the utility model is described, does not form the restriction to claim scope, and other substituting of being equal in fact that those skilled in that art can expect, all in the utility model protection domain.
