Abstract
The utility model relates to a sealing cup which comprises annular rubber, an annular metal framework and a spring. An annular lip is arranged on the inner side of the annular rubber, the metal framework is arranged inside the annular rubber, the spring is arranged at a position, of the lip, inside the sealing cup, the spring is an annular tension spring, and a recessed mark is arranged at a position 4 where the annular rubber contacts with a sealing cup seat 5. Arrangement of the mark of the sealing cup is improved by changing an original protrusive mark into the recessed mark, and when mounting, the sealing cup can be assembled more reliably and inclining due to a protrusion can be avoided, so that sealing performance of the sealing cup is improved.
Description
Technical field
The utility model relates to a kind of leather cup.
Background technique
Leather cup is dynamic sealing assembly commonly used in the mechanical system, is applied to the relatively low position of Sliding velocity.Leather cup is made up of metal frame, rubber cup and spring.At work, have the rubber cup of metal frame under the elastic reaction of spring, leather cup lip and rotatingshaft are tightly forced together, interdicted leakage-gap, reach the purpose of obturaging.Have the bigger lip of spring-back force with the sealing difference of other form leather cup that is to obturage, sealing contact surface is very narrow, and contact stress sharply distributes, and leather cup section configuration and banding spring make lip have axle and follow compensation performance preferably.Therefore, leather cup can obtain the better seal effect with less lip radial force.At present the leather cup of installing on the helicopter main reducing gear need arrange head-stamp with leather cup seated connection synapsis on leather cup, and head-stamp is according to the requirement of HB5936-7, head-stamp projection 0.2mm.In use, because head-stamp is protruding structure, and is positioned at the seal face of leather cup, therefore, the head-stamp projection can cause leather cup assembling ear end face to be difficult to be close to, and makes the certain angle of leather cup inclination, and then causes leakage of oil.
Summary of the invention
The purpose of this utility model provides a kind of leather cup, is implemented in that end face is close in the assembly process, does not produce inclination, guarantees seal action.
The technical solution of the utility model is, leather cup comprises ring-shaped rubber, metal frame, spring, described ring-shaped rubber inboard arranges annular lip, inside is provided with the metal frame of annular, the position that is positioned at lip in the inside of leather cup is provided with spring, and described spring is annular draught spring, is provided with head-stamp at 4 places, position of described ring-shaped rubber and leather cup seated connection tactile 5, described head-stamp is recessed and according to the requirement setting of HB5936-10, the degree of depth of head-stamp is 0.1～0.2mm.
The utility model is by improving the head-stamp setting of leather cup, changes the head-stamp of former projection into recessed head-stamp, when mounted, makes the leather cup assembling more reliable, can not improve the sealability of leather cup owing to projection produces.
