Utility model content
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of combined retainer, Neng Goubao
The concentricity of motor and screw rod is demonstrate,proved, it is easy for installation, while can reduce the elastic bending deflection of screw rod, improve the transmission essence of screw rod
Degree.
To achieve the above object, the utility model proposes a kind of combined retainers, including pedestal, fixing seat, locking
Nut, bearing, oil seal washer and bushing, described pedestal one end are provided with bearing hole, and the other end is provided with motor fixing seat, described to hold
Connection groove body is provided between repeated hole and motor fixing seat, for accommodating shaft coupling, motor fixing seat is used for the connection groove body
Motor is installed, the rotary shaft of motor and screw axis are sequentially connected by shaft coupling, and the load-bearing bore ends are installed with by bolt
Reservation, is provided at least one bearing in the bearing hole, and the bearing two sides are respectively arranged with oil seal washer, in the oil seal washer
It is provided with bushing, bushing side is provided with locking nut in the link slot body, and the locking nut is welded on bushing, passes through
Locking nut, which is welded on bushing, can preferably fix screw axis, reduce the collision between locking nut and bushing.
Preferably, there are two bearings for setting in the bearing hole.
Preferably, pedestal lower part two sides are respectively arranged with slippage slot, at least two are provided in the slippage slot
Fixed block is provided with dormant bolt on the fixed block, fixed block is fixed on mechanical equipment by dormant bolt, the seat
Body end portion is provided with pulling force and adjusts bolt, and the pulling force adjusts bolt and withstands on fixed block, adjusts bolt by rotation pulling force, can
To adjust the position that pedestal is equivalent to fixed block, and then screw axis can be tensed, reduce the elastic bending deflection of screw axis, into
And improve the transmission accuracy of screw axis.
Preferably, there are two fixed blocks for setting in the slippage slot.
The utility model has the beneficial effects that the utility model is by by pedestal, fixing seat, locking nut, bearing, oil seal washer
It is applied in retainer with bushing, can guarantee the concentricity of motor and screw rod, it is easy for installation, while can reduce the bullet of screw rod
Property bending deformation, improves the transmission accuracy of screw rod.
Detailed description of the invention
The above and other feature of the utility model, property and advantage will by it is following in conjunction with the accompanying drawings and embodiments

Specific embodiment
- Fig. 3 refering to fig. 1, a kind of combined retainer of the utility model, including pedestal 1, fixing seat 2, locking nut 3, axis
4, oil seal washer 5 and bushing 6 are held, described 1 one end of pedestal is provided with bearing hole 11, and the other end is provided with motor fixing seat 12, described
Connection groove body 13 is provided between bearing hole 11 and motor fixing seat 12, the connection groove body 13 is for accommodating shaft coupling, motor
The rotary shaft of motor and screw axis are sequentially connected by fixing seat 12 for installing motor, shaft coupling, and 11 end of bearing hole is logical
It crosses bolt and is installed with fixing seat 2, at least one bearing 4 is provided in the bearing hole 11,4 two sides of bearing are respectively arranged with
Oil seal washer 5 is provided with bushing 6 in the oil seal washer 5, and 13 neck bush of the connection groove body, 6 side is provided with locking nut 3, institute
It states locking nut 3 to be welded on bushing 6, can preferably fix screw axis by the way that locking nut 3 to be welded on bushing 6, drop
Collision between low locking nut 3 and bushing 6.There are two bearings 4 for setting in the bearing hole 11.The 1 lower part two sides of pedestal
It is respectively arranged with slippage slot 14, at least two fixed blocks 16 are provided in the slippage slot 14, are provided on the fixed block 16
Fixed block 16 is fixed on mechanical equipment by dormant bolt 17 by dormant bolt 17, and 1 end of pedestal is provided with pulling force tune
Bolt 18 is saved, the pulling force adjusts bolt 18 and withstands on fixed block 16, adjusts bolt 18, adjustable pedestal by rotation pulling force
1 is equivalent to the position of fixed block 16, and then screw axis can be tensed, and reduces the elastic bending deflection of screw axis, and then improve
The transmission accuracy of screw axis.There are two fixed blocks 16 for setting in the slippage slot 14.
A kind of combined retainer of the utility model, by by pedestal 1, fixing seat 2, locking nut 3, bearing 4, oil seal washer
5 and bushing 6 apply in retainer, can guarantee the concentricity of motor and screw rod, it is easy for installation, while can reduce screw rod
Elastic bending deflection improves the transmission accuracy of screw rod.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new
Scheme after type simple transformation belongs to the protection scope of the utility model.
