Embodiment
Explain below with reference to Figure of description a kind of slag stock pump that has a cooling sandwith layer of the present utility model being done with the grease lubricating bearing assembly.
A kind of slag stock pump grease lubricating bearing assembly that has cooling sandwith layer of the present utility model, its structure comprises pump shaft 1, labyrinth axle sleeve 2, bearing gland 3, bearing 4, back-up ring 5, bearing support 6, lubricating grease forced filling oil cup 7, felt collar 8, bearing gland clamping bolt 9 and bearing lock nuts 10, pump shaft 1, bearing 4, back-up ring 5 and labyrinth axle sleeve 2 are installed in the bearing support 6, circumferencial direction at bearing support 6 has adopted cooling sandwith layer 17 structures, the axial length dimension of cooling sandwith layer 17 is greater than the thickness size of the bearing of being installed 4, on two end faces of bearing support 6 closure plate 15 is installed, closure plate 15 is fastened on by closure plate fastening screw trip bolt 16 on two end faces of bearing support 6, forms two in the both sides of bearing support 6 and independently seals cooling chamber.Bearing gland 3 is in the outside of closure plate 15, and bearing gland clamping bolt 9 passes closure plate 15 bearing gland 3 is fastened on the bearing support 6.As shown in Figure 4.
Along the circumferential direction be provided with equally distributed cooling sandwith layer opening 18 on two end faces of bearing support 6, behind bearing support 6 castings, carry out the cleaning of casting sand from cooling sandwith layer opening 18 positions.Physical location at bearing support 6 end faces is provided with fastening screw 19 of equally distributed closure plate and the fastening screw 20 of bearing gland, in order to connecting of bearing support 6 and closure plate 15 and bearing gland 3.As shown in Figure 6.
Circumferencial direction at bearing support 6 has adopted annular cooling sandwith layer 17 structures, be respectively equipped with cooling water intake 24 and coolant outlet 21 at the radially position of cooling sandwith layer 17, and be connected with cooling sandwith layer 17 respectively, between cooling water intake 24 and coolant outlet 21, be provided with cooling partition wall 22, be provided with grease adding mouth 23 at cooling partition wall 22 positions.As shown in Figure 7.
During use, cooling water is connected to the cooling water intake 24 of bearing support 6, the effect of being cooled off partition wall 22, after cooling water entered cooling sandwith layer 17, to flowing, flowed out from coolant outlet 21 back of rounding along cooling sandwith layer 17 folk prescriptions of annular.Because the length dimension of cooling sandwith layer 17 is greater than the thickness size of bearing 4, and cooling water is along one week of outer ring circulation of bearing 4, therefore bearing 4 is played cooling action very fully, greatly reduced the operating temperature of bearing 4, the working life of effectively having improved bearing 4.The Seal cage of bearing support 6 both sides is independently, can be according to the difference of slag stock pump conveyance fluid temperature, and the cooling water pipeline at bearing support 6 two ends is carried out and connects or be connected in series.If the fluid temperature (F.T.) of carrying is not very high, the cooling water pipeline at bearing support two ends can be connected in series, be about to the coolant outlet 21 of bearing support one end and the cooling water intake 24 of the other end and join, to reduce the consumption of cooling water; The fluid temperature (F.T.) of carrying as the pomace stock pump is very high, can the cooling water pipeline at bearing support 6 two ends be carried out and connect, and is about to cooling water and introduces the cooling water intake 24 at bearing support two ends respectively, to strengthen the cooling effect to bearing.This slag stock pump grease lubricating bearing assembly that has cooling sandwith layer, when the slag stock pump is carried high temperature fluid, reduced the operating temperature of bearing effectively, improved the working life of bearing, and it is relatively simple for structure reasonable, manufacturing is easy, and working service is convenient, is a kind of very desirable slag stock pump bearing unit.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
