Abstract
The utility model discloses a lifting machine step, including the bearing frame body that links to each other with the lifting machine shell, setting up lower of lifting machine on the bearing frame body, still be provided with the tensioning screw rod on the bearing frame body, the tensioning screw rod passes through the nut and the lifting machine shell is fixed, and the spiro union is provided with the bearing cap on the bearing frame body, bearing cap and bearing frame body form airtight space, and the one end that the lifting machine is lower is located the epaxial bearing that still is provided with under the lifting machine in airtight space in airtight space. The utility model discloses simple structure, with low costs, excellent in use effect does not take the bearing cap of trompil through setting up, and the spindle nose disappearance of ensureing lower of lifting machine has been stopped the dust completely from the outside and has been got into the interior possibility of bearing in bearing frame inside airtight space, and the normal clear of work is ensured to the spoilage of reduction bearing, has improved work efficiency, has reduced bearing replacement cost and cost of maintenance.
Description
Technical field
The utility model relates to a kind of bearing support, is specifically related to a kind of elevator lower shafts bearing.
Background technique
The step of lift, arranges porose usually on bearing cap, for passing for elevator lower shafts; the cooperation in elevator lower shafts and hole is inaccurate under normal circumstances; the gap of 0.1 millimeter is all left in the interior outside in hole, and this gap adds dust and enters chance in bearing, the bearing support of this kind of structure; in use; often occur lift stuck phenomenon, cause machine halt trouble, can have influence on vertical cellar for storing things time serious cannot normally calcine; the cleaning work of bearing bothers very much, and labor intensity is large.
Model utility content
For problems of the prior art, the purpose of this utility model is that design provides step in a kind of lifting.
Described a kind of elevator lower shafts bearing, comprise the bearing support body be connected with lift shell, the elevator lower shafts be arranged on bearing support body, described bearing support body is also provided with tensioning screw, described tensioning screw is fixed by nut and lift shell, it is characterized in that, described bearing support body is spirally connected is provided with bearing cap, described bearing cap and bearing support body form confined space, one end of described elevator lower shafts is in confined space, and the elevator lower shafts being positioned at confined space is also provided with bearing.
Described a kind of elevator lower shafts bearing, the inwall that it is characterized in that described bearing support body is provided with a circle groove, is provided with felt oil seal in described groove.
Described a kind of elevator lower shafts bearing, is characterized in that described ditch groove depth 65mm, wide 5mm.。
The utility model structure is simple, cost is low, using effect is good, by arranging the bearing cap not with perforate, guarantee that the spindle nose disappearance of elevator lower shafts is in the inner confined space of bearing support, stop dust from outside completely and entered possibility in bearing, reduced the spoilage of bearing, guarantee normally carrying out of work, improve working efficiency, reduce bearing replacing cost and maintenance cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-lift shell, 2-bearing support body, 3-elevator lower shafts, 4-tensioning screw, 5-nut, 6-bearing cap, 7-confined space, 8-bearing, 9-groove, 10-felt oil seal.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, a kind of elevator lower shafts bearing of the utility model, comprise the bearing support body 2 be connected with lift shell 1, the elevator lower shafts 3 be arranged on bearing support body 2, bearing support body 2 is also provided with tensioning screw 4, tensioning screw 4 is fixed by nut 5 and lift shell 1, bearing support body 2 is spirally connected and is provided with bearing cap 6, bearing cap 6 and bearing support body 2 form confined space 7, one end of elevator lower shafts 3 is in confined space 7, and the elevator lower shafts 3 being positioned at confined space 7 is also provided with bearing 8.The inside of bearing support body 2 is provided with the dark 65mm of a circle, the groove 9 of wide 5mm, is provided with felt oil seal 10 in groove 9.
The utility model bearing cap 6 top does not arrange perforate, spindle nose disappearance is inner at bearing support, stop dust from outside completely and enter possibility in people's bearing, inner side turning one circle groove 9, load onto felt oil seal 10 in it to seal, this felt oil seal 10 carrys out thick malthoid with 5 millis and makes, during assembling, its internal diameter and axle journal external diameter closely cooperate, therefore, also the possibility that dust enters Bearing inner is substantially eliminated from inner side, the lower bearing of this structure, in actual using process, run 1 year fault-free to occur, two or three months is not had to carry out bearing replacing relative to existing lower bearing, substantially increase working efficiency, decrease maintenance and disassembly cost.
