Description
Technical field
This utility model relates to the rotating base of a kind of star-pursuing antenna.
Background technology
The most vehicle-mounted, shipborne radar mainly comprises star-pursuing device and receptor, and other accessories.Due to car, ship
In motor process and satellite operating in orbit, make the antenna in star-pursuing device need constantly and use multivariant turn
Dynamic to adjust angle and corresponding satellite all the time.Star-pursuing campaign for antenna includes the rotation of horizontal direction and the pitching of antenna
Motion, and the rotation of horizontal direction is common tumbler with rotating base.As it is shown in figure 1, in the prior art, sky is installed
The belt pulley 1 ' of line can drive belt 3 ' to carry out rotation operation by motor 2 ', and the tensioning of belt 3 ' uses customary in the art
Regulating wheel 4 ' carry out tensioning.
But, along with vehicle-mounted, the development of shipborne radar, the next generation needs the overall construction design of more compact, then chases after
The internal structure of star device needs further compact design, and in the case of a kind of compact design, regulating wheel occupies in star-pursuing device
Space, portion, is easier to produce with miscellaneous part to interfere.And do not use the problem that regulating wheel then cannot solve belt tension.
Therefore, need a kind of new technical scheme to solve the problems referred to above.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, it is provided that a kind of star-pursuing antenna rotating base, energy
Enough minimizing while providing belt tension function takies star-pursuing device inner space.
For achieving the above object, this utility model can adopt the following technical scheme that
A kind of star-pursuing antenna rotating base, the belt pulley including substrate, being arranged on substrate, the electricity being arranged on substrate
Machine, connection motor output shaft and the belt of belt pulley；Described substrate is provided with some installing holes, and installing hole is lengthwise
Shape, described motor is fixed on substrate with coordinating of installing hole by screw or bolt, and the screw rod of screw or the screw rod of bolt
Move on longitudinally in installing hole.
Compared with prior art, this utility model no longer has regulating wheel carry out tensioning, but have employed by screw or
Bolt is the mobile tensioning making motor realize belt away from the mode of a segment distance relative to belt pulley in installing hole, and these spiral shells
Nail or bolt are also the fixing devices being fixed on substrate by motor simultaneously, thus are not increasing the feelings of other tensioners
Under condition, the same function realizing tensioning, kill two birds with one stone.So can no longer there is regulating wheel, decrease and occupy star-pursuing dress
Put inner space, the most integrally-built densification, miniaturization.
For achieving the above object, this utility model also can adopt the following technical scheme that
A kind of star-pursuing antenna rotating base, the belt pulley including substrate, being arranged on substrate, the electricity being arranged on substrate
Machine, connection motor output shaft and the belt of belt pulley；It is characterized in that: described substrate is provided with some installing holes, and installs
Hole is longitudinal, and described motor is fixed on substrate with coordinating of installing hole by screw or bolt, screw or the spiral shell of bolt
Bar cross-sectional diameter is not more than the width of installing hole, and the cross-sectional diameter of the screw rod of screw or bolt is less than installing hole lengthwise side
To length.
Compared with prior art, this utility model no longer there is regulating wheel carry out tensioning, but have employed by screw
The cross-sectional diameter of screw rod or bolt, less than the length of installing hole longitudinally, makes screw or bolt move in installing hole and makes electricity
Machine realizes the tensioning of belt relative to belt pulley away from the mode of a segment distance, and these screws or bolt are also by electricity simultaneously
Machine is fixed on the fixing device on substrate, thus in the case of not increasing other tensioners, same realizes tensioning
Function, kills two birds with one stone.So can no longer there is regulating wheel, decrease and occupy star-pursuing device inner space, be conducive to entirety
The densification of structure, miniaturization.

Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are only used for
This utility model is described rather than limits scope of the present utility model, after having read this utility model, art technology
Personnel all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
Refer to shown in Fig. 2 to Fig. 4, the open a kind of star-pursuing antenna rotating base of this utility model, including substrate 1, install
Belt pulley 2 on substrate 1, installation motor 3, connection motor output shaft 31 and the belt 4 of belt pulley 2 on substrate 1.Institute
Stating substrate 1 and be provided with some installing holes 11, and installing hole 11 is longitudinal, described motor 3 is by screw or bolt 5 and installation
The cooperation in hole 11 is fixed on substrate 1, and the screw rod (not shown) of the screw rod (not shown) of screw or bolt is in installing hole 11
Longitudinally on move.Described screw or bolt 5 are four, and these screws or bolt 5 are also to be fixed by motor 3 simultaneously
Fixing device on substrate 1, thus in the case of not increasing other tensioners, the same function realizing tensioning.
Shown in Fig. 4, described motor 3 and belt pulley 2 are positioned at the both sides of substrate 1.And in the present embodiment, screw or the screw rod of bolt
Cross-sectional diameter is not more than the width of installing hole 11, and the cross-sectional diameter of the screw rod of screw or bolt is less than installing hole 11 lengthwise
The length in direction, thus realize the screw rod (not shown) of the screw rod (not shown) of screw or the bolt lengthwise side in installing hole 11
Move up.
Compared with prior art, this utility model no longer there is regulating wheel carry out tensioning, but have employed by screw
The cross-sectional diameter of screw rod or bolt, less than the length of installing hole longitudinally, makes screw or bolt move in installing hole and makes electricity
Machine realizes the tensioning of belt relative to belt pulley away from the mode of a segment distance, and these screws or bolt are also by electricity simultaneously
Machine is fixed on the fixing device on substrate, thus in the case of not increasing other tensioners, same realizes tensioning
Function, kills two birds with one stone.So can no longer there is regulating wheel, decrease and occupy star-pursuing device inner space, be conducive to entirety
The densification of structure, miniaturization.
