The purpose of the utility model is to provide a kind of water lubrication guide bearing, solves the problem of existing water lubrication guide bearing non-refractory.
The purpose of the utility model realizes through following technological scheme:
The water lubrication guide bearing of the utility model axially is evenly equipped with a plurality of first water inlets along it; On the inwall of water lubrication guide bearing, be uniformly distributed with and the identical feed water tank of the said first water inlet quantity; Have second water inlet on the said feed water tank; This second water inlet is connected with an end of first water inlet, and the other end of first water inlet is communicated with the hyperbaric chamber of water pump; Part with the pump shaft friction on the inwall of said water lubrication guide bearing is provided with wearing layer, radially is provided with a plurality of osculums that are communicated with the water pump low pressure chamber on the water lubrication guide bearing.
Wherein: said feed water tank along the water lubrication guide bearing radially be projected as " H " shape, said second water inlet is positioned at the geometrical center of " H " shape feed water tank; Said feed water tank is five, and at the inwall circumference uniform distribution of water lubrication guide bearing, the degree of depth of feed water tank is 1.25～1.75mm; Said water lubrication guide bearing and pump shaft are Spielpassung, and the inwall of water lubrication guide bearing and the radial clearance between the pump shaft are 0.18～0.22mm; Said wearing layer built-up welding is in the inwall of water lubrication guide bearing, and the material of wearing layer is a cemented carbide, and hardness is HRC44～54; The thickness of said wearing layer is 1.5mm; The length of this water lubrication guide bearing is 1.5 with the internal diameter ratio.
Advantage of the utility model and good effect are:
1. the water lubrication guide bearing of the utility model has been uniformly distributed with the feed water tank of first water inlet and " H " shape above that; Have second water inlet on the feed water tank; First water inlet is communicated with the hyperbaric chamber of water pump, and osculum communicates with the low pressure chamber of water pump, guarantees that water pump has the rubbing surface of lubricated current through guide bearing during operation all the time; In time take away frictional heat, make the water lubrication guide bearing can be high temperature resistant.
The water lubrication guide bearing of the utility model in the friction portion built-up welding of inwall wearing layer, can bear thermal shock and unaffected.
Description of drawings
Fig. 1 is the internal structure sectional view of the utility model;
Fig. 2 is that A among Fig. 1 is to view;
Wherein: 1 is the water lubrication guide bearing, and 2 is pump shaft, and 3 is first water inlet, and 4 is second water inlet, and 5 is feed water tank, and 6 is osculum, and 7 is wearing layer.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail.
Like Fig. 1, shown in Figure 2; The water lubrication guide bearing 1 of the utility model axially is evenly equipped with a plurality of first water inlets 3 (present embodiment is five) along it, on the inwall of water lubrication guide bearing 1, is uniformly distributed with and the identical feed water tank 5 of said first water inlet, 3 quantity; This feed water tank 5 along water lubrication guide bearing 1 radially be projected as " H " shape; Have 4, the second water inlets 4, second water inlet on the feed water tank 5 and be positioned at the geometrical center of " H " shape feed water tank 5, guarantee that pressure distribution is even; Said second water inlet 4 is connected with an end of first water inlet 3, and the other end of first water inlet 3 is communicated with the hyperbaric chamber of water pump.The feed water tank 5 of present embodiment also is five, at the inwall circumference uniform distribution of water lubrication guide bearing 1; The degree of depth of " H " shape feed water tank 5 is keys of the whole bearing performance of influence; Under the situation of other parameter constant; The change in depth of " H " shape feed water tank 5 is bigger to the influence of bearing performance, and through calculating, groove depth is proper between 1.25～1.75mm; Can make bearing that better comprehensive performance is arranged, the degree of depth of present embodiment feed water tank 5 is 1.5mm.Radially be provided with a plurality of osculums 6 that are communicated with the water pump low pressure chamber on the water lubrication guide bearing 1.Part with pump shaft 2 frictions on the inwall of said water lubrication guide bearing 1 is provided with wearing layer 7; These wearing layer 7 built-up welding are in the inwall of water lubrication guide bearing 1; The material of wearing layer 7 is a cemented carbide, and like Ni60, hardness is HRC44～54; Consider the feasibility of the wearing and tearing and the built-up welding of bearing, the thickness of wearing layer 7 is 1.5mm.Water lubrication guide bearing 1 is a Spielpassung with pump shaft 2, and the radial clearance between the inwall of water lubrication guide bearing 1 and the pump shaft 2 is 0.18～0.22mm, and this gap can make bearing that bearing capacity is preferably arranged.The length of water lubrication guide bearing 1 is 1.5 with the internal diameter ratio.
The working principle of the utility model is:
Lubricated water in the water pump hyperbaric chamber gets into guide bearing from five first water inlets 3 that axially are uniformly distributed with, and flowing through through second water inlet 4 is positioned at the feed water tank 5 of middle " H " shape of guide bearing, flows to the two ends of bearing, forms the pressure-bearing moisture film, shown in the arrow among Fig. 1; This pressure-bearing moisture film is kept apart guide bearing and pump shaft 2, and lubricated at last water flows away from the osculum 6 of guide bearing.First water inlet 3 of guide bearing is communicated with the hyperbaric chamber of water pump, and osculum 6 communicates with the low pressure chamber of water pump, guarantees that water pump has the rubbing surface of lubricated current through guide bearing during operation all the time, in time takes away frictional heat.7～120 ℃ of the temperature ranges of lubricated water, guide bearing can be born thermal shock and unaffected.
