Description
Technical field
The utility model relates to the dynamic oil resistant compression testing device of a kind of bearing sealed ring, for detecting the sealability of bearing sealed ring under high temperature, high pressure, dynamic rotary.
Background technique
At present, the bearing in motor car engine all needs to adopt seal ring to realize and sealing between axle and casing.The lubricant oil of seal ring contact has the feature of high temperature, high pressure, dynamic rotary, its sealability and working life most important, but automobile production producer does not carry out special detection for the sealability of engine bearing seal ring, cannot the performance of accurate assurance bearing sealed ring.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the dynamic oil resistant compression testing device of a kind of bearing sealed ring.
Technical solutions of the utility model are as follows: the dynamic oil resistant compression testing device of a kind of bearing sealed ring, it is characterized in that: bearing support is the straight tube structure of open at both ends, and be supported on test axle by the left bearing that is arranged side by side and right bearing, separated by spacer ring between left bearing and right bearing, form the toroidal cavity of accommodating lubricant oil between described spacer ring and bearing support, this toroidal cavity is in communication with the outside by the oil filler that bearing support is offered; Described left bearing and test axle between and be equipped with the first seal ring between right bearing and test axle, first seal ring is flush-mounted in the annular groove on test axle, between described left bearing and bearing support and between right bearing and bearing support, be equipped with the second seal ring, the second seal ring is flush-mounted in the annular groove on bearing support inwall; Be pasted with end cap in the both ends of the surface of described bearing support, the middle part perforate of this end cap is avoided testing axle, and is provided with tegillum in the mider hole of the end cap in the left side, and the left end head-shield of test axle enters by described tegillum, and tegillum is connected with test axle by bolt.
Two bearings are arranged in an enclosed space by the utility model, between the inner ring of bearing and test axle and all sealed by seal ring between outer ring and bearing support.Oil filler on bearing support connects lubricant pipe, testing machine is delivered in the toroidal cavity in bearing support after being heated by lubricant oil, the oil pressure of setting lubricant oil, then starting electrical machinery motoring ring test axle rotates, the working state of seal ring can be simulated, by the oil pressure on viewing test machine or range estimation end cap mider hole place with or without leakage of oil, the sealability of bearing sealed ring can be judged.
In order to simplified structure, convenient for assembly, be convenient to be connected with motor, at the right-hand member suit shaft coupling of described test axle, this shaft coupling is connected with test axle by flat key, and shaft coupling is fixed on by the positioning screwn that radial direction wears and tests on axle.
Conveniently be connected with lubricant pipe, described oil filler is positioned at the middle part of bearing support, and this oil filler is tapped hole.
Beneficial effect: the utility model structure is simple, compact, easy accessibility, by the working state of simulation seal ring high temperature, high pressure, dynamic rotary, can detect the sealability of seal ring, and testing result accurately, reliably.
Accompanying drawing explanation
Fig. 1 is the phase diagram before the utility model pressurization.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, bearing support 1 is the straight tube structure of open at both ends, and is supported on test axle 4 by the left bearing 2 that is arranged side by side and right bearing 3, and the two ends of test axle 4 all exceed the end face of bearing support 1 corresponding end.Separated by spacer ring 5 between left bearing 2 and right bearing 3, form the toroidal cavity of accommodating lubricant oil 6 between spacer ring 5 and bearing support 1, this toroidal cavity is in communication with the outside by the oil filler 1a that bearing support 1 is offered.Oil filler 1a is positioned at the middle part of bearing support 1, and this oil filler 1a is tapped hole, so that connect lubricant pipe, the lubricant oil after heating is sent in the toroidal cavity in bearing support 1 by testing machine by lubricant pipe.
As shown in Figure 1, be equipped with the first seal ring 7, first seal ring 7 and be flush-mounted in the annular groove tested on axle 4 between left bearing 2 and test axle 4 and between right bearing 3 and test axle 4.Be equipped with the second seal ring 8, second seal ring 8 between left bearing 2 and bearing support 1 and between right bearing 3 and bearing support 1 to be flush-mounted in the annular groove on bearing support 1 inwall.Be pasted with end cap 9 in the both ends of the surface of bearing support 1, this end cap 9 is by circumferentially equally distributed bolt and bearing support 1 fix.Avoid testing axle 4 in the middle part perforate of end cap 9, and be provided with tegillum 10 in the mider hole of the end cap 9 in the left side, the left end head-shield of test axle 4 enters by tegillum 10, and the bolt that tegillum 10 is worn by its central horizontal is connected with test axle 4.At the right-hand member suit shaft coupling 11 of test axle 4, this shaft coupling 11 is connected with test axle 4 by flat key, and shaft coupling 11 is fixed on test axle 4 by the positioning screwn 12 that radial direction wears.Shaft coupling 11, for being connected with motor, making driven by motor test axle 4 and rotates, be in the working state of high temperature, high pressure, dynamic rotary, thus detect the sealability of seal ring with the lubricant oil of simulating in bearing support 1.
