Background technology
Bearing seal is primarily to and prevents the lubricant of Bearing inner from leaking outside, and prevents the moisture of outside, dust, foreign body etc. from entering Bearing inner, then affects behavior in service and the service life of bearing. The bearing of a kind of favorable sealing property, it is necessary to possess under arbitrary cond, the feature that can operate safely and enduringly. But seal typically via soft sealing ring, steel ball is not had supporting role, in addition it is also necessary to be separately provided gripper shoe and be supported steel ball avoiding steel ball pressure excessive, it is therefore necessary to improve.
Summary of the invention
It is an object of the invention to for the above-mentioned problems in the prior art, it is provided that a kind of simple in construction, bearing can be played the high leakproofness deep groove ball bearing of support and sealing function very well.
The purpose of the present invention can be realized by following technical proposal: a kind of high leakproofness deep groove ball bearing, including bearing inner race, bearing outer ring, retainer and steel ball, it is characterized in that: bearing inner race two end faces vertically are respectively equipped with annular brace groove, bearing outer ring is respectively equipped with cannelure between two end faces and bearing outer ring inner surface vertically, and cannelure cell wall is provided with annular seal groove, also include two annular brace circles, bracing ring includes annular and strengthens plate and be coated on the rubber layer strengthened outside plate, strengthen plate and rubber layer form annular brace ring and annular sealing ring respectively, a described pushing out ring and sealing ring are embedded in support slot and seal groove respectively, described bracing ring is additionally provided with through strengthening the hole, location that plate is arranged, and cannelure cell wall is provided with fixing groove, and with hole, location and fixing slot fit, bracing ring and bearing outer ring can be fixed respectively by bolt.
It is bolted bracing ring, therefore bolt is fixed with strengthening plate, utilize and strengthen that pushing out ring that plate formed is countershaft holds inner ring and bearing outer ring forms good supporting role, avoid steel ball stress excessive, strengthen being coated with rubber layer outside plate simultaneously, bearing is played sealing function by the sealing ring formed by rubber layer, therefore has only to install bracing ring and bearing can play well support and sealing function, and structure is very simple simultaneously.
In above-mentioned a kind of high leakproofness deep groove ball bearing, a described pushing out ring is bent to form for strengthening plate inner edge.
Therefore convenient production.
In above-mentioned a kind of high leakproofness deep groove ball bearing, described reinforcement plate outer rim is arranged towards seal groove inner bending.
Therefore bulk strength is higher, compacter.
In above-mentioned a kind of high leakproofness deep groove ball bearing, described hole, location is uniformly distributed along bracing ring circumference.
Compared with prior art, present invention have the advantage that
It is bolted bracing ring, therefore bolt is fixed with strengthening plate, utilize and strengthen that pushing out ring that plate formed is countershaft holds inner ring and bearing outer ring forms good supporting role, avoid steel ball stress excessive, strengthen being coated with rubber layer outside plate simultaneously, bearing is played sealing function by the sealing ring formed by rubber layer, therefore has only to install bracing ring and bearing can play well support and sealing function, and structure is very simple simultaneously.
