Description
Technical Field
The utility model relates to a bucket-wheel reclaimer, concretely relates to bucket-wheel reclaimer with shaft seal protection device.
Background
The raw materials are mainly transferred by the bucket-wheel stacker-reclaimer, and the daily operation rate of each bucket-wheel stacker-reclaimer is about 96 percent. The two ends of the bearing seat of the prior bucket wheel shaft are not sealed, accumulated materials and sundries easily enter the bearing to cause shaft damage, so that the service life of the bucket wheel bearing is only 3-6 months, the replacement is frequent, the labor intensity is high, the equipment utilization rate is low, and the production delay is caused.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to overcome the defects of the prior art, the utility model provides a bucket-wheel reclaimer with shaft seal protection device, this bucket-wheel reclaimer can effectively seal the wheel axle.
The technical scheme is as follows: the bucket wheel reclaimer with the wheel shaft sealing protection device comprises a bearing seat, a wheel shaft protruding out of the bearing seat, a first sealing element fixedly connected to the outer side surface of the bearing seat and sleeved on the wheel shaft, and a second sealing element tightly connected to the wheel shaft and rotating along with the wheel shaft; the second sealing element is tightly abutted to the outer side of the first sealing element, a gap is formed between the opposite surfaces of the first sealing element and the second sealing element, the gap and the outer surface of the wheel shaft are encircled to form a sealing cavity, and sealing grease is filled in the sealing cavity.
Wherein the first sealing element and the second sealing element are both circular rings.
The outer side surface of the first sealing element and the inner side surface of the second sealing element protrude out of a plurality of coaxial sealing parts, a sealing groove is formed between every two adjacent sealing parts, and the sealing groove of the first sealing element is correspondingly matched with the sealing part of the second sealing element; the first and second seals are engaged with each other through respective seal portions and seal grooves.
The first sealing element is welded on the outer side surface of the end cover of the bearing seat in a full-welding mode.
And the second sealing piece is welded with the outer surface of the axle in a full welding mode.
The sealing grease filled in the sealing cavity is 2# lithium-based grease.
Has the advantages that: this bucket-wheel reclaimer sets up shaft seal protection device at the bearing frame lateral surface, forms the multichannel protection through first sealing member, second sealing member, the sealed chamber of packing sealed fat, avoids long-pending material and debris to get into the damage that the bearing caused the bucket-wheel, promotes life.

FIG. 2 is a schematic structural view of a first sealing member of the present invention;
fig. 3 is a schematic structural diagram of a second sealing member in the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-3, the bucket-wheel reclaimer with the wheel axle seal protection device comprises a bearing seat (1), a wheel axle 2, a first sealing element 3 which is welded on the outer side surface of an end cover of the bearing seat 1 in a full-weld mode and sleeved on the wheel axle 2, and a second sealing element 4 which is welded on the surface of the wheel axle 2 in a full-weld mode and rotates along with the wheel axle 2.
Wherein, the first sealing element 3 and the second sealing element 4 are both in the shape of circular rings. The outer side surface of the first sealing element 3 and the inner side surface of the second sealing element 4 respectively protrude from the outer edges in opposite directions to form a plurality of coaxial annular sealing parts 6, and a sealing groove 7 is formed between the adjacent sealing parts 6. The sealing groove 7 of the first seal 3 and the sealing portion 6 of the second seal 4 are correspondingly adapted. The first seal member 3 and the second seal member 4 are rotated in tight engagement with each other through the respective seal portions 6 and seal grooves 7.
Between the opposing surfaces of the first seal 3 and the second seal 4, near the circumference of the wheel axle 2, there is a gap, which surrounds the outer surface of the wheel axle 2 to form a seal chamber 5, which seal chamber 5 is filled with a sealing grease. Specifically, the sealing grease filled in the sealing cavity 5 is 2# lithium-based grease, and the sealing grease also serves as a lubricating material so as to rotate freely.
In this bucket-wheel reclaimer, second sealing member 4 full weld forms the first layer protection in the outside, second sealing member 4 establish with the sealed chamber 5 of packing lubricating grease between the first sealing member 3 form the second floor protection, first sealing member 3 full weld forms the third layer protection at the layer of end cover surface, sealed oil blanket plays the fourth layer protection in the bearing frame. Therefore, the bucket wheel shaft bearing is protected from being damaged by multi-level protection, the service life of the bearing is prolonged, the service life of the bearing of the bucket wheel stacker-reclaimer provided with the device is 60-72 months, and the failure rate is remarkably reduced.
