Abstract
The utility model is related to a kind of valve actuator spindle locating mechanism, including main shaft, with the main shaft is connected bearing, sliding axle and positioning sleeve；The end of the main shaft is provided with eccentric grove, the inner ring of the bearing is stuck in the eccentric grove, the outer ring of the bearing is contacted with the inwall of the sliding axle, hole back-up ring of the outside of the bearing provided with limitation bearing axial movement, the sliding axle, which is arranged on, to be used in the positioning sleeve of bearing outer ring radial positioning.The eccentric grove location structure of valve actuator spindle locating mechanism of the present utility model, with simple in construction, without increasing axial direction positioning device；Compact conformation, saves space, and handling are simple.
Description
Technical field
The utility model belongs to valve actuator technical field, and in particular to a kind of valve actuator spindle locating mechanism.
Background technology
In the executing agency of valve actuator, main shaft 10 axially moves while doing gyration, installed in positioning
Sliding axle 13 in set 11 is moved axially with main shaft, but need not be rotated with main shaft, and the bearing on main shaft needs inside and outside
Circle is fixed, and carries out axially position, to meet the demand of transmission load.
At present, the inner ring axially position of executing agency's middle (center) bearing is generally using structures such as the shaft shoulder, back-up ring, double round nuts.But
It is that inner space is limited in structure is performed, not only installs, dismantles relatively difficult, and some Functional Designs can not realize.Such as
Shown in Fig. 1, the back-up ring 12 on the right side of bearing is installed, sliding axle 13 is necessarily designed to the form of through hole, installed from sliding axle endoporus, when
Axis hole hour is slided, back-up ring can not just be installed, this structure will not be able to realize.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem and provide a kind of valve actuator main shaft orientation machine
Structure.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of valve actuator spindle locating mechanism, including main shaft, with the main shaft it is connected bearing, sliding axle and positioning
Set；The end of the main shaft is provided with eccentric grove, and the inner ring of the bearing is stuck in the eccentric grove, the outer ring of the bearing and institute
State the inwall contact of sliding axle, hole back-up ring of the outside provided with limitation bearing axial movement of the bearing, the sliding axle peace
In for the positioning sleeve to bearing outer ring radial positioning.
The one end open of the sliding axle, for installing bearing and the hole back-up ring, the other end is blind end, for
It is connected from axle.
The eccentric grove location structure of valve actuator spindle locating mechanism of the present utility model, with simple in construction, without
Increase axial direction positioning device；Compact conformation, saves space, and handling are simple.
Brief description of the drawings
Fig. 1 is the schematic diagram of existing valve actuator spindle locating mechanism；
Fig. 2 is the schematic diagram for the valve actuator spindle locating mechanism that the utility model is provided.
Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Fig. 2 a kind of valve actuator spindle locating mechanism, including：
Main shaft 10, the bearing being connected with the main shaft, sliding axle 50 and positioning sleeve 20；The end of the main shaft is provided with inclined
Heart groove 70, the inner ring 60 of the bearing is stuck in the eccentric grove, the outer ring 40 of the bearing and the inwall of the sliding axle 50
Contact, the hole back-up ring 30 of the outside of the bearing provided with limitation bearing axial movement, the sliding axle 50, which is arranged on, to be used for pair
In the positioning sleeve 20 of bearing outer ring radial positioning.
Wherein, the one end open of the sliding axle 50, for installing bearing and the hole back-up ring, the other end is closing
End, for being connected with the valve plate of connecting valve from axle, realization is rotated according to the rotation of main shaft, and realization is opened valve
Open or shutoff operation.
During installation, first bearing outer ring is inserted in sliding axle, then bearing is stuck in spindle nose by mounting hole back-up ring
In eccentric grove, now the axial direction of bearing, radial direction are not all positioned completely, finally load positioning sleeve, complete the radial direction of bearing outer ring
Positioning, such bearing inner race is axially fixed in eccentric grove, and now the axle center of bearing and main shaft rotation center axis A are concentric.
The eccentric grove centre of gyration of main shaft is axis B, and eccentric grove does gyration, the side of eccentric grove with main shaft around axis A
Edge is always more than bearing inner race radius, therefore just completes the inner ring axially position of bearing
When main shaft does gyration, because bearing centre is consistent with main shaft rotation center, bearing outer ring is radially fixed, no
Rotate, when main shaft axial reciprocating is moved, sliding axle synchronously carries out axial reciprocating fortune under the drive of bearing with main shaft
It is dynamic.
The eccentric grove location structure of valve actuator spindle locating mechanism of the present utility model, with simple in construction, without
Increase axial direction positioning device；Compact conformation, saves space, and handling are simple.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
Claims (2)
1. a kind of valve actuator spindle locating mechanism, it is characterised in that bearing, slip are connected including main shaft, with the main shaft
