Abstract
The utility model relates to a sealing end cap of bearings, the bottom of the conical inner bore of a bearing end cover 1 is provided with an oil baffle ring 3, and the external periphery of the oil baffle ring 3 is provided with an annular slot. When an input and an output shafts run, the lubricating oil splashed from the bearing rolling balls can rotating flow along the annular slot on the oil baffle ring 3, and then the lubricating oil can flow into an oil pool form an oil return bore. The structure avoids the lubricating oil resisting in the inner and outer surfaces of an oil seal 2, and therefore, the ageing, deformation and abrasion of the oil seal can be decelerated. The utility model improves production quality, saves material and reduces cost.
Description
The utility model relates to the dynamic sealing technology of rotating machinery.
The leakproof oil seal technology at the input of existing machinery equipment, output shaft place, all adopt oil sealing, disc, Oil Guide screw thread to be lubricated oily leakproof seal, wherein, oil sealing plays the crux seal action, oil sealing contacts for a long time with input, output shaft, cause that unavoidably thereby aging, wearing and tearing cause leakage of oil, change oil sealing.This maintenance, working strength of workers is big, and long in time limit.
The purpose of this utility model is to provide a kind of bearing seal end cap of good leak-proof effect.
The utility model is on the excircle that adds an oil deflector (3), oil deflector (3) bottom the cone-shaped inner hole of existing bearing (ball) cover (1) circular groove to be arranged.
Advantage of the present utility model is: the sealing that 1, has improved input, output shaft place; 2, improve the working life of oil sealing, reduced the replacing frequency of oil sealing; 3, saved material, Cost of repair and maintenance, improved working efficiency.
Fig. 1 is the utility model structural drawing.
Further specify as follows below in conjunction with accompanying drawing to the utility model and working principle:
As shown in the figure, bearing (ball) cover (1) is a cone structure, in its cone-shaped inner hole bottom oil deflector (3) is arranged, the internal diameter and the running shaft of oil deflector (3) have certain interval, and on the excircle of oil deflector (3), be processed with circular groove, oil sealing (2) is contained in the taper hole bottom of bearing (ball) cover (1), the rear portion of oil deflector (3), is used for stopping that extraneous harmful matter enters the oil sump in the bearing (ball) cover (1).When input, output shaft running, oily centrifugal to the conical surface of bearing (ball) cover (1) from what sputter between bearing ball, lubricant oil is past dirty along the conical surface, locate to oil deflector (3), along the circular groove eddy flow on oil deflector (3) excircle, flow into oil sump from spill port at last, such flow process that so circulates, thus the inner and outer surface that has guaranteed sealing and oil sealing (2) is avoided corrosion.
Claims (2)
1, a kind of bearing seal end cap is characterized in that oil deflector (3) is arranged at the cone-shaped inner hole bottom of bearing (ball) cover (1), on the excircle of oil deflector (3) circular groove is arranged.
2, bearing seal end cap according to claim 1 is characterized in that between the internal diameter of oil deflector (3) and the running shaft certain interval being arranged.
