Technical field
The utility model relates to a kind of dirt-proof boot of high pressure roller extruding grinding machine movable axis, belongs to high pressure abrasive dust equipment technical field.
Background technology
The main working parts of high pressure roller grinder is two cylindrical roller pinch rollers that are arranged in parallel, and when equipment work, material is involved between two rolling wheel set also crushed; One of them roll-in crop rotation System of Rotating about Fixed Axis motion, another rolling wheel set its axis in rotary course can move, to adapt to by the degree of irregularity of crushing material.Pressure between high pressure roller grinder two rollers is generally 50～300 MPa, and therefore rolling wheel set can be subject to very large shock loading in the course of the work, causes horizontal vibration and twisting vibration that main shaft is strong.For this reason, the main shaft of high pressure roller grinder can be designed to syllogic, rolling wheel set is installed at the maximum gauge place, middle part that is main shaft, the minimum diameter place, two ends of main shaft is arranged in bearing block for supporting, the stress shaft shoulder is set between the middle part of main shaft and two ends, bears the mechanical strength of horizontal vibration and twisting vibration to improve main shaft.
Conventionally in the working environment of high pressure roller extruding grinding machine, dust is more, and high pressure roller squeezing mill machine is manufactured and maintenance cost is all higher, therefore need to pay attention to especially the anti-dust performance of high pressure roller extruding grinding machine, to reduce wearing and tearing and the maintenance cost of moving component, and main shaft especially, its active force bearing is large, in the process of running, between its stress shaft shoulder and bearing block, enter dust, easily cause the work energy consumption of high pressure roller extruding grinding machine to raise, the rate of wear of main shaft and bearing block is accelerated, and has reduced the service life of high pressure roller extruding grinding machine.
Utility model content
The deficiency that the utility model exists for prior art just; a kind of dirt-proof boot of high pressure roller extruding grinding machine movable axis is provided; can carry out proofing dust and protecting to the main abrading section of movable axis, produce with the stress shaft shoulder and the bearing block of avoiding movable axis the rising of work energy consumption and the shortening in service life that friction causes high pressure roller extruding grinding machine.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A dirt-proof boot for high pressure roller extruding grinding machine movable axis, comprises base and is arranged at the bearing block on base, and the axial location movable axis that can move with respect to base;
Described movable axis comprises the stress axis shoulder inside supporting base end portion and the two ends that are positioned at two ends, and described supporting base end portion is arranged in described bearing block; Also comprise dirt-proof boot, described dirt-proof boot movable set, on described movable axis, and is positioned at the crossover position of described supporting base end portion and described stress axis shoulder.
As the improvement of technique scheme, described dirt-proof boot comprises slot end and wide mouth end, and described slot end is positioned at described supporting base end portion, and described wide mouth end is positioned at described stress axis shoulder.
As the improvement of technique scheme, between described dirt-proof boot and described movable axis, be provided with wool felt.
As the improvement of technique scheme, described dirt-proof boot is provided with groove, and described wool felt is arranged in described groove.
As the improvement of technique scheme, described groove is at least two, is provided with a described wool felt in each described groove.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The dirt-proof boot of high pressure roller extruding grinding machine movable axis described in the utility model, dirt-proof boot can coordinate described movable axis to move well, and the dust that can effectively prevent movable axis rolling wheel set position flies away and deposits to the crossover position of described stress axis shoulder and described supporting base end portion, be deposited on the wearing and tearing that the dust of the crossover position of described stress axis shoulder and described supporting base end portion causes bearing block and described movable axis comparatively obvious, reduce loss and energy consumption that above-mentioned wearing and tearing can significantly reduce high pressure roller extruding grinding machine, and reduce its maintenance cost.And wool felt is set, and further to improve the sealing between described dirt-proof boot and described movable axis, improve dust-proof effect, and the mounting means of concrete wool felt is provided, be convenient to installation and replacing and good seal performance.
Brief description of the drawings
Fig. 1 is the dust-proof cover structure schematic diagram of high pressure roller extruding grinding machine movable axis described in the utility model.
Detailed description of the invention
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, push the dust-proof cover structure schematic diagram of grinding machine movable axis for high pressure roller described in the utility model.The dirt-proof boot of high pressure roller described in the utility model extruding grinding machine movable axis, comprising: base and be arranged at the bearing block 1 on base, and the axial location movable axis that can move with respect to base; It is characterized in that, described movable axis comprises the stress axis shoulder 3 inside supporting base end portion 2 and the two ends that are positioned at two ends, and described supporting base end portion 2 is arranged in described bearing block 1; Also comprise dirt-proof boot, described dirt-proof boot movable set, on described movable axis, and is positioned at the crossover position of described supporting base end portion 2 and described stress axis shoulder 3.The dirt-proof boot of described structure can coordinate described movable axis to move well, when described dirt-proof boot touches after bearing block 1, described dirt-proof boot can be fixing by described bearing block 1 under frictional force effect, described movable axis rotates in described dirt-proof boot, thereby avoid rubbing between described stress axis shoulder 3 and bearing block 1, and dust security and the convenience of clearing up between described bearing block 1 and described dirt-proof boot are all greater than the dust between the described stress axis shoulder 3 of cleaning and bearing block 1, and cleaning only can cause the bearing block 1 that is easy to change to produce wearing and tearing with described dirt-proof boot, therefore said structure can prevent that the dust at movable axis rolling wheel set position from flying away and depositing to described stress axis shoulder 3 and the crossover position of described supporting base end portion 2 effectively, be deposited on described stress axis shoulder 3 comparatively obvious with the wearing and tearing that the dust of the crossover position of described supporting base end portion 2 causes bearing block 1 and described movable axis, reduce loss and energy consumption that above-mentioned wearing and tearing can significantly reduce high pressure roller extruding grinding machine, and reduce its maintenance cost.
