Reinforced bearing cooling device

Abstract

The invention discloses a reinforced bearing cooling device. The device comprises a bearing oil tank, a thrust head which is arranged in the bearing oil tank and used for transmitting axial force to a bearing lens plate from a spindle, a cooler and a bearing plate, wherein the cooler and the bearing plate are arranged in the bearing oil tank; an oil guide chamber is arranged at the position, between the thrust head and the cooler, of the outer circle of the thrust head, and is wholly in a circular ring shape, a plurality of guide pieces are arranged on the inner side wall of the oil guide chamber in a surrounding manner and comprises blades and triangular supports connected with the blades together, the blades and the triangular supports are arranged in the circumferential direction, an oil path channel is formed among blades and the triangular supports of every two adjacent guide pieces, oil inlets are formed in one ends of the blades, oil outlets are formed in one ends of the triangular supports, openings of the oil inlets are formed in the upper ends and the lower ends of the corresponding blades, and are formed upwards and downwards in the axial direction of the oil guide chamber, and the oil outlets are formed towards the outer side of the oil guide chamber. The reinforced bearing cooling device is simple in structure and convenient to mount, and the cooling efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of bearing conduction and heat dissipation, in particular to a device for strengthening heat dissipation of a bearing. Background technique [0002] At present, most vertical sliding bearings are self-lubricating bearings. The lubricating oil inside the bearing does not depend on the outside, and only the internal mechanical structure of the bearing obtains the circulating power. During use, when running at low speed, the fluidity of the lubricating oil inside the oil tank is low, and the hot oil does not have enough power to flow to the cooler for cooling. In this way, the hot oil continues to participate in lubrication to form a short circuit, and the dynamic pressure oil film becomes thinner, which is not conducive to Bearings run reliably and stably for a long time. [0003] Therefore, strengthening the guidance and dredging of the lubricating oil circuit inside the bearing at low speed is a more feasib...
