Abstract
It the utility model is related to bearing relevant device technical field, more particularly to a kind of both-end independence rotary connection structure, including cylindrical bearing seat, the both ends of the bearing block are equipped with rotating shaft, and one end of the rotating shaft is extended to outside bearing block, and the other end is stretched into bearing block, and it is fixedly connected with the bearing seat by rolling bearing, the outer ring of the rolling bearing is fixedly connected with the inwall of bearing block, and the inner ring of the rolling bearing is set in outside rotating shaft, and is fixedly connected with rotating shaft.This structure can realize that the rotating shaft at both ends individually rotates, complementation interference, and the rotating shaft direction of rotation at both ends can be with the contrary, simple and compact for structure, good appearance, has good practicality, the problem of instead of tradition needs while individually use two rotational structures.
Description
Technical field
It the utility model is related to bearing relevant device technical field, and in particular to a kind of both-end independence rotary connection structure.
Background technology
In some mechanical structures, it is sometimes desirable to two kinds of rotational structures, or even direction of rotation is on the contrary, most conventional at present do
Method is to use two independent rotational structures, but this spline structure often becomes complicated, while can be influenceed again between equipment
Layout.
Utility model content
The purpose of this utility model is to provide a kind of both-end independence rotary connection structure simple in construction, reasonable in design.
To achieve these goals, the technical solution adopted in the utility model is：A kind of both-end independence rotary connection structure,
Including cylindrical bearing seat, the both ends of the bearing block are equipped with rotating shaft, and one end of the rotating shaft is extended to outside bearing block, another
End is stretched into bearing block, and is fixedly connected with the bearing seat by rolling bearing, the outer ring of the rolling bearing and bearing block it is interior
Wall is fixedly connected, and the inner ring of the rolling bearing is set in outside rotating shaft, and is fixedly connected with rotating shaft.
A kind of both-end independence rotary connection structure as described above, further illustrates to be that the both ends of the bearing block are provided with
Bearing cap, the rotating shaft are stretched out among bearing cap.
A kind of both-end independence rotary connection structure as described above, further illustrates and is, the bearing cap and bearing block it
Between be bolted to connection.
A kind of both-end independence rotary connection structure as described above, further illustrates to be that the bearing cap is close to the axis of rolling
The middle part for holding side is provided with sealing shroud, and the sealing shroud extends into bearing block, and the sealing shroud is set in outside rotating shaft, described close
Sealing ring is provided between big envelope and rotating shaft.
A kind of both-end independence rotary connection structure as described above, further illustrates to be that the rotating shaft is provided with spacing ring,
The end face of the spacing ring and sealing shroud is abutted against, and sealing ring is provided between the spacing ring and sealing shroud.
A kind of both-end independence rotary connection structure as described above, further illustrate be arranged with outside the bearing block to
Few two adpting flanges, the adpting flange are fixedly connected with the bearing seat.
The beneficial effects of the utility model are：This structure can realize that the rotating shaft at both ends individually rotates, complementation interference, and two
The rotating shaft direction of rotation at end can be so that on the contrary, simple and compact for structure, good appearance, has good practicality, instead of tradition needs
The problem of individually using two rotational structures simultaneously.

Embodiment
The utility model embodiment is further elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of both-end independence rotary connection structure that the present embodiment provides, including cylindrical bearing seat 1, institute
The both ends for stating bearing block 1 are equipped with rotating shaft 2, and one end of the rotating shaft 2 is extended to outside bearing block 1, and the other end stretches into bearing block 1
It is interior, and be fixedly connected by rolling bearing 3 with bearing block 1, the outer ring of the rolling bearing 3 is fixed with the inwall of bearing block 1 to be connected
Connect, the inner ring of the rolling bearing 3 is set in outside rotating shaft 2, and is fixedly connected with rotating shaft 2, so as to so that both ends rotating shaft 2 with
Rotated between bearing block 1, realize that the rotating shaft 2 at both ends individually rotates, complementation interference, and the direction of rotation of rotating shaft 2 at both ends can
With on the contrary, instead of the problem of tradition needs individually to use two rotational structures simultaneously.
Further, bearing cap 4 can be provided with the both ends of the bearing block 1, the rotating shaft 2 is stretched among bearing cap 4
Go out, the sealing to bearing block 1 is realized by bearing cap 4, so as to avoid exotic from entering in bearing block 1, the structure is existed
It is safer during operation, it is fixedly connected between the bearing cap 4 and bearing block 1 by bolt 5, so as to by screwing out bolt
5, bearing cap 4 is removed, certain bearing cap 4 can also be directly welded on bearing block 1.
When in use, in order that the sealing effectiveness of the structure is more preferable, so as to increase the use range of the structure, therefore can be
The bearing cap 4 is provided with sealing shroud 6 close to the middle part of the side of rolling bearing 3, and the sealing shroud 6 extends into bearing block 1, described
Sealing shroud 6 is set in outside rotating shaft 2, and sealing ring 7 is provided between the sealing shroud 6 and rotating shaft 2, further, can also be in institute
State rotating shaft 2 and be provided with spacing ring 8, the end face of the spacing ring 8 and sealing shroud 6 abuts against, the spacing ring 8 and sealing shroud 6 it
Between be again provided with sealing ring 8, so as to pass through sealing ring 8 realize sealing.
It is attached in order to facilitate between the structure and other devices, at least two can be arranged with outside the bearing block 1
Individual adpting flange 9, the adpting flange 9 are fixedly connected with bearing block 1, so as in connection, with bolt by the company in the structure
Acting flange 9 is connected with the adpting flange on other devices.
The utility model is not limited to examples detailed above, in claims limited range of the present utility model, this
The various deformations or amendments that art personnel can make without creative work are protected by this patent.
