Abstract
The utility model discloses a radiating sliding bearing which comprises a bearing, an oil tank for installation and an upper end cover, wherein the oil tank for installation is arranged on the outer periphery of the bearing; the bottom of the oil tank is provided with sheet radiating fins. In the utility model, by arranging the sheet radiating fins at the bottom of the oil tank, the temperature reduction effect is improved, the working stability of the radiating sliding bearing is improved and the limit of an operating temperature is expanded.
Description
Technical field
The utility model relates to a kind of bearing, specifically the radiating type sliding bearing.
Background technique
The radiating type sliding bearing is mainly used in the vitals that electric power system is a motor, and the stability of its service behaviour directly affects the working condition of electric power system.The general ballast that influences the end cover type sliding bearing is mainly temperature variation, because the higher temperature that causes of rotational speed of motor is too high, lubricating oil viscosity descends, and the situation that oil film rigidity descends influences the motor effect.The existing falling temperature technique of end cover type sliding bearing is mainly realized by cooling recirculation system, lacks other approach.
China's utility model patent patent No. 200620105225.4 discloses a kind of end cover type sliding bearing, comprise bearing housing and end cap, the bearing housing two ends are respectively equipped with inner oil seal and outer oil seal, end cap is arranged on inner oil seal one side, end cap is provided with sealing gland, nearly inner oil seal end is provided with a floating seal ring on the end cap, and the chamber that forms between chamber that forms between described floating seal ring and the sealing gland and end cap and the bearing housing communicates with each other.This technology is mainly considered is that the problem of bearing lubrication oil leakage is not studied or technical clarification the cooling problem that this patent relates to.
Summary of the invention
The utility model provides a kind of simple in structure, radiating type sliding bearing of expanding the high temperature operating limit.
A kind of radiating type sliding bearing, comprise installation fuel tank and upper end cap that bearing, bearing periphery are provided with, described fuel tank bottom is provided with the sheet radiating fin, mainly acting as of tank mounting gives bearing cooling and lubricated, but oily temperature can generally raise and reduce lubricated and radiating effect under the bearing length time service, by radiating fin is set in its bottom the temperature of fuel tank internal is dispersed into the serviceability temperature that reduces bearing in the air fast.
Described upper end cap surface is provided with radiating fin, to reduce the serviceability temperature of bearing, expansion bearing high temperature operating limit.
The utility model increases cooling-down effect by being provided with the sheet radiating fin in the fuel tank bottom, improves the working stability of radiating type sliding bearing and expands the serviceability temperature limit.
Description of drawings
Fig. 1 is the utility model radiating type sliding bearing master TV structure schematic representation.
Embodiment
Referring to accompanying drawing 1, a kind of radiating type sliding bearing of the utility model comprises installation fuel tank 2 and upper end cap that bearing 4, bearing 4 peripheries are provided with, and described fuel tank 2 bottoms are provided with sheet radiating fin 3, heat in the fuel tank 2 is dispersed in the atmosphere, improves radiating effect bearing 4.
Be provided with radiating fin 1 as preferred upper end cap surface, improve radiating effect.
Claims (2)
1. a radiating type sliding bearing comprises installation fuel tank (2) and upper end cap that bearing (4), bearing (4) periphery are provided with, and it is characterized in that: described fuel tank (2) bottom is provided with sheet radiating fin (3).
2. radiating type sliding bearing as claimed in claim 1 is characterized in that: described upper end cap surface is provided with radiating fin (1).
