Abstract
The utility model relates to a contact type sealing structure in a deep groove ball bearing, which comprises a capped edge and a contact lip. The contact lip comprises an upper lip (1) which is not contacted with the capped edge, and a left lower lip (3) and a right lower lip (4) which are connected with the upper lip (1) into a whole; the left lower lip (3) and the right lower lip (4) are contacted with the capped edge. The utility model has the advantages that the utility model has the good functions of preventing grease inside the bearing from leaking outwards, and preventing external foreign bodies such as dust and water from entering into the bearing; the start up torque and the operating friction torque are little.
Description
Technical field
The utility model relates to a kind of deep groove ball bearing, relates in particular to the contact seal structure in this deep groove ball bearing.
Background technique
Traditional deep groove ball bearing sealing configuration has two kinds: a kind of is contact seal, and another kind is a noncontact seal.The advantage of noncontact seal is that starting torque is less, is restricted but use not as the good seal performance of contact seal because of its sealability.
By Fig. 1, Fig. 2 as seen, have only bottom right lip 20 to contact during bearing working, and upper lip 10 and lower-left lip 30 are all discontiguous with rib, so the water-proof performance of three such lip formula contact seal structures is relatively poor with rib.
Summary of the invention
The utility model technical issues that need to address have provided a kind of contact seal structure in deep groove ball bearing, are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: rib with contact lip; Described contact lip comprises and the discontiguous upper lip of rib, the lower-left lip and the bottom right lip that fuse with upper lip; Described lower-left lip contacts with rib with the bottom right lip;
Compared with prior art, the beneficial effects of the utility model are: have the good function that the bearing internal grease is outwards revealed that prevents; Have good prevent foreign matter such as dust and water etc. and enter the function of bearing inside; Starting torque and operation friction moment are less.
Description of drawings
Fig. 1 is the contact seal structure in deep groove ball bearing in the prior art;
Fig. 2 is the enlarged view of Fig. 1 at the K place;
Fig. 3 is the utility model structural drawing;
Fig. 4 is the enlarged view of Fig. 3 at the I place;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 3, Fig. 4 as seen: the utility model comprises: rib with contact lip; Described contact lip comprises and the discontiguous upper lip 1 of rib, the lower-left lip 3 and the bottom right lip 4 that fuse with upper lip 1; Described lower-left lip 3 contacts with rib with bottom right lip 4;
Described upper lip 1 is hard and thick shape; It is to contact and form between lower-left lip 3 and bottom right lip 4 the first V-type groove 7 with first rib 8 that described lower-left lip 3 and bottom right lip 4 contact with rib; In the joint of upper lip 1 and lower-left lip 3 and bottom right lip 4, the second V-type groove 2 is arranged near the top of lower-left lip 3; In the joint of upper lip 1 and lower-left lip 3 and bottom right lip 4, a breach 6 is arranged near the top of bottom right lip 4;
The position of first rib 8 of described close lower-left lip 3 can also comprise that is extended second a downward rib 5.
In the utility model:
1. upper lip 1 (non-contact lip) characteristics: thick and hard.Function: the grease that throws away when making bearing operation is introduced raceway groove, guarantee bearing good lubrication, reduced the internal pressure that bottom right lip 4 bears simultaneously, can prevent effectively that grease from leaking.
2. the function of the second V-type groove 2: make the root deliquescing of lower-left lip 3, promptly strengthened the pliability and the elasticity of lower-left lip 3.
3. the function of lower-left lip 3 and bottom right lip 4: prevent that internal grease from revealing and foreign matter to intrusion bearing inside.
The function of second rib 5 and lower-left lip 3 and bottom right lip 4 together interference fit form seal ring.
5. the function of breach 6: the structure of improving lower-left lip 3 and bottom right lip 4..
6. the function of the first V-type groove 7: make lower-left lip 3 and bottom right lip 4 form labyrinths, the improvement sealability.
7. the function of first rib 8: this rib and the bottom right lip 4 light weight amounts of contact, can reduce starting friction moment and operation friction moment.
The utility model also has favorable waterproof property except the advantage with contactless and contact-type.
Claims (3)
1. contact seal structure in deep groove ball bearing comprises: rib with contact lip; It is characterized in that: described contact lip comprises and the discontiguous upper lip of rib (1), the lower-left lip (3) and the bottom right lip (4) that fuse with upper lip (1); Described lower-left lip (3) contacts with rib with bottom right lip (4).
2. the contact seal structure in deep groove ball bearing according to claim 1 is characterized in that: described upper lip (1) is hard and thick shape; It is to contact and form between lower-left lip (3) and bottom right lip (4) the first V-type groove (7) with first rib (8) that described lower-left lip (3) and bottom right lip (4) contact with rib; On upper lip (1) and the joint of lower-left lip (3) and bottom right lip (4), the top of close lower-left lip (3) the second V-type groove (2) is arranged; On upper lip (1) and the joint of lower-left lip (3) and bottom right lip (4), the top of close bottom right lip (4) breach (6) is arranged.
3. the contact seal structure in deep groove ball bearing according to claim 1 and 2 is characterized in that: the position of first rib (8) of described close lower-left lip (3) can also comprise that is extended downward second rib (5).
