Abstract
The utility model discloses a dedicated integral type grease lubrication bearing support for ventilators. The bearing support is provided with a base and is characterized in that lower bearing supports are symmetrically arranged at two ends of the base and are integrated with the base, upper bearing covers are symmetrically fixed on the two lower bearing supports, bearing end covers are respectively and fixedly connected with the outer sides of the two groups of lower bearing supports and upper bearing covers, and oil seals are embedded in the bearing end covers and in center holes formed by the upper bearing covers and the lower bearing supports. The bearing support has the advantages of good coaxiality and verticality, simple structure, convenience in installation as well as low requirement for the technical level of assemblers, and is suitable for batch production and assembly; the sealing effect is good, so that lubricating grease for lubrication has low possibility of leakage, which can prolong the service life of bearings; and the height from the center of a main shaft of the bearing support to the bottom plane of the bearing support is shortened, so as to improve the operation stability, reduce the vibration value at the bearings, reduce the integral weight and machining cost and lower the manufacturing cost.
Description
Technical field
The utility model relates to a kind of ventilator dedicated integral formula grease lubricating bearing seat.
Background technique
Bearing support (case) is the critical piece of ventilator transmission group, and its structural type, lubricating system, machining accuracy to playing an important role in temperature rise, vibration and working life of bearing, directly have influence on the normal operation of ventilator in the operation process of ventilator.
At present, the main shaft of ventilator is generally selected bath lubrication bearing housing and two grease lubricating bearing seat dual modes arranged side by side for use.The machining of bath lubrication bearing housing is complicated, and manufacture cost is higher, and maintaining need have the special messenger to nurse, and sealing can not get fine solution, when ambient temperature or rotating speed are higher, at the shaft end seal place and the easy leakage of oil of junction plane of bearing housing base and loam cake.
Two grease lubricating bearing seats arranged side by side have simple in structure, advantage of low manufacturing cost, but when two bearing supports of assembling, the coaxality of two bearing supports and perpendicularity are difficult to accurate adjustment, just can cause bearing inner race and outer ring run-off the straight in case error occurs, thereby reduce the working life of bearing.In addition, two bearing support both sides arranged side by side are used the felt sealing usually, the felt sealing can only be prevented dust, when water or vapour or other impurity are arranged in transportation, preservation, Environmental Conditions, very easily invade in the bearing support, cause bearing rust, its greasy property is changed, bearing temperature raises, and lubricating grease leaks outside, and causes damage of bearings.
Summary of the invention
Problem to be solved in the utility model provides a kind of simple in structure, easy for installation, and installation precision guarantees easily, and good sealing effect can prolong the bearing ventilator dedicated integral formula grease lubricating bearing seat in working life.
The utility model is achieved in that it has a base, its special way is: the two ends at base are arranged with bearing base, bearing base and base are one, on two bearing bases, be symmetrically fixed with bearing upper cover, the outside at two groups of bearing bases and bearing upper cover is connected with bearing (ball) cover respectively, is installed with oil sealing respectively at bearing (ball) cover and in the center hole of bearing upper cover and bearing base composition.
Above-mentioned ventilator dedicated integral formula grease lubricating bearing seat is provided with mutual corresponding locating stud and positioning hole at bearing base respectively with the junction plane place of bearing upper cover, to guarantee the installation precision of bearing saddle bore.
Above-mentioned ventilator dedicated integral formula grease lubricating bearing seat is evenly equipped with gusset in bearing (ball) cover, so that store lubricating grease.
Above-mentioned ventilator dedicated integral formula grease lubricating bearing seat, described oil sealing is the skeleton rubber oil sealing.
Above-mentioned ventilator dedicated integral formula grease lubricating bearing seat is provided with the oil hole and the greasing oil nozzle that communicate with its inner chamber, so that the new lubricating grease of regular replenishment on bearing upper cover.
Above-mentioned ventilator dedicated integral formula grease lubricating bearing seat, described bearing base and base are the foundry goods of one.
The utility model has the advantages that:
1, owing to is arranged with bearing base at the two ends of base, bearing base and base are one, therefore the bearing base and the bearing upper cover that are positioned at the base two ends can form by the boring machine time processing, coaxality and perpendicularity are good, simple in structure, easy for installation, technical merit to the assembler is less demanding, is fit to produce in batches assembling.
2, owing to be installed with oil sealing respectively at bearing (ball) cover and in the center hole of bearing upper cover and bearing base composition, can prevent that foreign intrusion bearing inside from making bearing rust, corrosion bearing, good sealing effect uses grease lubrication to be difficult for leaking, and can prolong bearing working life.
3, because bearing base and base are one, can reduce the height of the bearing support alignment of shafts, can improve the stability of ventilator operation, reduce the vibration values of bearing portion, reduce whole weight and machining expense, reduce manufacture cost to the bearing support bottom plane.
4, bearing base and base are one, and intensity is guaranteed, and can be used for casing and support and are welded into whole ventilator transmission group, also the installation basis of suitable water cement concrete pouring.
