Abstract
The utility model relates to a bolt, in particular to a bearing sleeve sealing bolt. The bearing sleeve sealing bolt comprises a screw head and a screw rod connected with the screw head. Threads are arranged on the screw rod. A screw rod transition part is arranged between the screw rod and the screw head. A circular groove is arranged in the connection position of the screw rod transition part and the screw head. A sealed ring is arranged in the circular groove in a sleeved mode. The connection position of the screw rod transition part and the screw head is a cambered surface, wherein the cross section of the cambered surface is cone-shaped. The bearing sleeve sealing bolt is good in sealing performance and simple in structure.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of bearing seal bolt.
Background technique
It is fixing that the bearing centre bearer bush adopts bearing housing bolt and external component to implement usually.The screw rod that traditional bearing housing bolt includes the spiral shell head and is connected with the spiral shell head, screw rod is provided with screw thread, is provided with the screw rod transition portion between screw rod and the spiral shell head.This type of bolt is in the operating mode that applies to the stuffing box bearing that needs sealing the time, between screw rod and the mounting hole without any sealing mechanism, can have the situation of leaking in the mounting hole.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of good airproof performance, bearing housing sealing bolt simple in structure.
For achieving the above object, the utility model provides following technological scheme: a kind of bearing housing sealing bolt, the screw rod that includes the spiral shell head and be connected with the spiral shell head, screw rod is provided with screw thread, be provided with the screw rod transition portion between screw rod and the spiral shell head, it is characterized in that: the joining place of described screw rod transition portion and spiral shell head offers annular recess, is arranged with seal ring in the annular recess, and the joining place of screw rod transition portion and screw rod is the tapered cambered surface of cross section.
Adopt technique scheme, by offering annular recess at the joining place of screw rod transition portion and spiral shell head, and in annular recess, seal ring is set, after arranging like this, can guarantee and mounting hole between sealing, the situation that makes bolt in fixation procedure, can not cause stuffing box bearing to be revealed.The setting of the cambered surface of the joining place taper of screw rod transition portion and screw rod then is in order to increase the force intensity that is subjected to of bolt.
The utility model further is set to: be evenly equipped with anti-turnover bar-shaped trough on the side face of screw rod transition portion.
Adopt technique scheme, setting can be prevented that bolt is in and gets loose in the mounting hole and circumferentially implement to rotate like this.
The utility model further is set to: offer at least one locating slot on the screw rod.
Adopt technique scheme, the setting of locating slot is can access further location after screw thread in screw rod and the mounting hole is screwed on the screw rod, prevents from skidding or getting loose.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
A kind of bearing housing sealing bolt as shown in Figure 1, the screw rod 2 that includes spiral shell head 1 and be connected with spiral shell head 1, screw rod 2 is provided with screw thread, be provided with screw rod transition portion 3 between screw rod 2 and the spiral shell head 1, screw rod transition portion 3 offers annular recess 4 with the joining place of spiral shell head 1, be arranged with seal ring 5 in the annular recess 4, screw rod transition portion 3 is the tapered cambered surface of cross section 6 with the joining place of screw rod 2.In the such scheme, by offering annular recess 4 at screw rod transition portion 3 and the joining place of spiral shell head 1, and at the annular recess 4 interior seal rings 5 that arrange, after arranging like this, can guarantee and mounting hole between sealing, the situation that makes bolt in fixation procedure, can not cause stuffing box bearing to be revealed.Screw rod transition portion 3 then is in order to increase the force intensity that is subjected to of bolt with the setting of the cambered surface 6 of the joining place taper of screw rod 2.
In the utility model embodiment, in order to prevent that bolt from occuring circumferentially to skid after installation, for bearing housing guarantee fixedly is provided, be evenly equipped with anti-turnover bar-shaped trough 31 on the side face of screw rod transition portion 3, the quantity of bar-shaped trough 31 can be decided according to design.Stability when guaranteeing that further bolt fixedly offers at least one locating slot 21 on the screw rod 2, its quantity also can be decided according to design.
