Abstract
The utility model discloses a kind of automobile hub unit of mandrel band seal groove, comprise outer ring, inner ring, steel ball and retainer, sealing member and mandrel, described mandrel is provided with groove with sealing member joining place.The utility model effectively improves the leak tightness of hub, long service life.
Description
Technical field
The utility model relates to a kind of automobile hub unit, is specifically related to a kind of automobile hub unit of mandrel band seal groove.
Background technology
In recent years, China's auto trade was in the period of developing rapidly, and volume of production and marketing improves constantly, and consider from long term growth, each maker and user have higher requirement to complete vehicle quality.Automobile hub unit is as the critical component connecting car chassis main body and tire, be used for load-bearing and provide accurate guiding for the rotation of wheel hub, the hub manufacturing high-quality has become the common effort target of each automobile hub bearing manufacturing and processing enterprise domestic.Hermetically-sealed construction occupancy volume in the space shared by bearing and cost of automobile hub unit is very little, but but plays very important effect in bearing use procedure.If bearing felt ability is bad, the intrusions such as extraneous silt, dust and steam can be caused, make it that abnormal sound occur, increase the weight of the wearing and tearing of raceway groove and steel ball, make steel ball, channel surface spalling fatigue, serious affects its service life, also can cause that wheel is stuck suddenly causes serious accident in some cases.Visible long life bearing be unable to do without excellent hermetically-sealed construction, and excellent bearing felt performance is the favourable guarantee of long life bearing and failure-free support.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of automobile hub unit of mandrel band seal groove, effectively improves the leak tightness of hub, long service life.
The technical scheme that the utility model technical solution problem adopts is: a kind of automobile hub unit of mandrel band seal groove, comprise outer ring, inner ring, steel ball and retainer, sealing member and mandrel, it is characterized in that: on described mandrel, be provided with groove with sealing member joining place.
The beneficial effects of the utility model are: on mandrel, be provided with groove with sealing member joining place, when outer ring is relative with mandrel rotate time ensure sealing effectiveness, effectively improve the leak tightness of hub, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the utility model embodiment mandrel upper groove and sealing member joining place enlarged drawing.
Below in conjunction with accompanying drawing, the utility model is described further.
Detailed description of the invention
As shown in accompanying drawing 1, Fig. 2, a kind of hub of special nut structure, hub comprises outer ring 1, inner ring 2, cover of dust 3, steel ball 4 and retainer 5, sealing member 6 and mandrel 7, mandrel 7 is provided with groove 9 with sealing member 6 joining place, actual groove 9 contacts with the lip of sealing member 6 and seals (as shown in Figure 2), effectively can improve the sealing property of hub.Two retainers 5 make steel ball 4 uniform on raceway, and each retainer 5 respectively installs 12 steel balls 4; Sealing member 6 and cover of dust 3 make whole working position define a sealing system, do not affect, prevent grease from outflowing by dust; Bolt 8 is for being connected with the wheel rim of automobile.
During assembling, to outer ring 1, inner ring 2 and mandrel 7 carry out demagnetization process, clean each parts, first bolt 8 is pressed onto on mandrel 7, two retainers 5 fill steel ball 4 respectively, one group of retainer 5 is loaded outer ring 1, then indentation sealing part 6 on outer ring 1, again outer ring 1 is put on mandrel 7, be arranged on groove 9 one side contacts on the lip of the sealing member 6 on outer ring 1 and mandrel 7, again another group retainer 5 is loaded outer ring 1, then inner ring 2 is put on mandrel 7, be pressed into press, then riveted is carried out to mandrel 7, prevent inner ring 2 from coming off in operational process, outer ring 1 is pressed into cover of dust 3, hub inside is made to form a sealing system, complete the assembling of hub.
