Description
Technical Field
The utility model belongs to the technical field of mechanical transmission, especially, relate to a split type bearing frame.
Background
Since a bearing is used as an essential component of modern mechanical equipment and is widely applied to various rotating parts, a bearing housing as an outer support of the bearing is also widely used. Split type bearing frame is also by a large amount of applications as one kind of bearing frame, however, current split type bearing frame, most all need use the bolt to carry out locking connection to the pedestal, and the installation is all more troublesome with the dismantlement, and the change time is long, and wastes time and energy, and work efficiency is low.
Disclosure of Invention
To the problem that prior art exists, the utility model provides a split type bearing frame.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a split type bearing frame, includes pedestal and upper base body down, the bilateral symmetry of pedestal bottom plate is provided with the bearing frame fixed orifices down, the top of pedestal is provided with down semi-circular through-hole down, the bottom of upper base body is provided with first semi-circular through-hole, but lower semi-circular through-hole and first semi-circular through-hole match each other and make up into a circular shape bearing mounting hole, the dovetail has been seted up along mounting hole diameter direction in the pedestal top down, the dovetail level runs through two side end faces about the pedestal down, the upper base body bottom is provided with trapezoidal arch along mounting hole diameter direction, trapezoidal arch can be arranged in the dovetail and can the dovetail slide relatively, and with the length phase-match of dovetail.
The dovetail groove penetrates through one side end face of the lower base body in the horizontal direction, the other side end face opposite to the dovetail groove does not penetrate through the dovetail groove, and the length of the trapezoidal protrusion is matched with that of the dovetail groove.
The length of the trapezoidal projection is symmetrical about the axis of the mounting hole by taking the shorter end as a reference.
The utility model has the advantages that:
the utility model provides a split type bearing frame, this bearing frame is through the dovetail of pedestal down and the trapezoidal bellied mutually supporting of last pedestal, alright with effectual pinning two parts of pedestals, other connection structure such as having avoided using bolt and nut to connect, and after the mounting hole was advanced in the bearing installation, the radial degree of freedom of this bearing frame is also restricted, consequently, can make the bearing frame under the supplementary condition of no other external mechanism, easily realize split type bearing frame from the locking, moreover, the steam generator is simple in structure, the dismouting is convenient, can effectively improve work efficiency.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-4, a split bearing seat belongs to the technical field of mechanical transmission, and has the advantages of simple structure, convenient assembly and disassembly, and effective improvement of working efficiency.
The utility model discloses a split type bearing frame, including lower pedestal 1 and upper seat body 2, split type bearing pedestal can be convenient for the dismouting of bearing to also do benefit to when the bearing frame is changed, only change the serious half bearing frame of wearing and tearing, need not whole change, it is extravagant to have avoided unnecessary. Bearing frame fixed orifices 3 are symmetrically arranged on both sides of the bottom plate of the lower seat body 1, and the bearing frame fixed orifices 3 are used for installing and fixing bearing frames. The top of lower pedestal 1 is provided with lower semicircular through-hole 4, and the bottom of upper pedestal 2 is provided with first semicircular through-hole 5, and lower semicircular through-hole 4 can match each other with first semicircular through-hole 5 and make up into a circular shape bearing mounting hole 6, and mounting hole 6 is used for the installation of bearing. The top end of the lower seat body 1 is provided with a dovetail groove 7 along the diameter direction of the mounting hole 6, the dovetail groove 7 horizontally penetrates through the left side end face and the right side end face of the lower seat body 1, the bottom end of the upper seat body 2 is provided with a trapezoidal protrusion 8 along the diameter direction of the mounting hole 6, the trapezoidal protrusion 8 can be arranged in the dovetail groove 7 and can slide relative to the dovetail groove 7 and is matched with the dovetail groove 7 in length, and after the trapezoidal protrusion 8 slides into the dovetail groove 7, the bearing seat can be easily assembled and mounted.
The dovetail groove 7 penetrates through one side end face of the lower base body 2 in the horizontal direction, the other side end face opposite to the dovetail groove does not penetrate through the dovetail groove, the length of the trapezoidal protrusion 8 is matched with that of the dovetail groove 7, one side end face does not penetrate through the dovetail groove, limiting combination of the bearing seats can be easily achieved during combined installation of the bearing seats, alignment is not needed, and the dovetail groove is convenient and efficient.
The length of the trapezoidal protrusion 8 is symmetrical with respect to the axis of the mounting hole 6 by taking the shorter end as a reference, so that the mounting of the upper base body 2 can be facilitated without distinguishing the mounting direction of the upper base body 2.
The combination method of the present invention is described below with reference to the drawings.
The method comprises the following steps: aligning any end of the trapezoidal bulge 8 at the bottom end of the upper seat body 2 with the dovetail groove 7 on the side surface of the lower seat body 1;
step two: sliding the trapezoidal protrusion 8 along the dovetail groove 7 until the trapezoidal protrusion 8 cannot slide forwards continuously;
step three: the bearing is rotated into the bearing mounting hole 6;
step four: and (5) finishing the installation.
The dismounting process is the reciprocal of the mounting process, namely the bearing is taken out firstly, and then the trapezoidal protrusion 8 slides out along the dovetail groove 7.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
