Abstract
A kind of hydraulic turbine recovers axle and runner coupling arrangement, it is characterized in that: comprise servomotor cylinder, bolt, piston, servomotor cylinder cap, piston snap ring, axle sleeve, oil pipe seat, runner hub core, pin, snap ring, seal joint and recovery axle, described servomotor cylinder and servomotor cylinder cap are closed by bolt handle, described piston and runner hub core are clamped by piston snap ring, described runner hub core and oil pipe seat are closed by bolt handle, described axle sleeve and oil pipe seat interference fit, described snap ring and servomotor cylinder cap are closed by bolt handle, described seal joint is compressed by servomotor cylinder cap and snap ring, described recovery axle is blocked by snap ring, play position-limiting action, described recovery axle is subject to axle sleeve and seal joint supports, the utility model recovers Axial and radial and is subject to the spacing of axle sleeve and seal joint, axle sleeve and seal joint can adjust when mounted, oil pipe seat and servomotor cylinder cap out-of-alignment problem can be solved, snap ring also plays the effect of axial limiting simultaneously.
Description
Technical field:
The utility model belongs to the instruction of rotary wheel of water turbine stroke and connects, and particularly relates to a kind of rotary wheel of water turbine stroke signal display equipment.
Background technology:
Rotary wheel of water turbine stroke signal display equipment, essence recovers axle one end to be connected with runner, recover the axle other end to be connected with runner stroke display board, when the action of runner servomotor, recover axle along with action, the stroke of servomotor is consistent with the stroke recovering axle, and namely the stroke display board recovering axle connection is the stroke of runner servomotor.Recover mainly to lean on nut lock before axle is connected with runner servomotor cylinder, in this case, recover axle radial direction be often subject to two spacing, namely oil pipe seat and servomotor cylinder cap is spacing, if servomotor cylinder cap and the processing of oil pipe seat cause disalignment, recover axle and will be subject to very large torsion, force recovery axle to twist off.
Utility model content:
In order to overcome the defect of prior art, the invention provides a kind of hydraulic turbine and recovering axle and runner coupling arrangement.
The technical solution of the utility model is: a kind of hydraulic turbine recovers axle and runner coupling arrangement, it is characterized in that: comprise servomotor cylinder, bolt, piston, servomotor cylinder cap, piston snap ring, axle sleeve, oil pipe seat, runner hub core, pin, snap ring, seal joint and recovery axle, described servomotor cylinder and servomotor cylinder cap are closed by bolt handle, described piston and runner hub core are clamped by piston snap ring, described runner hub core and oil pipe seat are closed by bolt handle, described axle sleeve and oil pipe seat interference fit, described snap ring and servomotor cylinder cap are closed by bolt handle, described seal joint is compressed by servomotor cylinder cap and snap ring, described recovery axle is blocked by snap ring, play position-limiting action, described recovery axle is subject to axle sleeve and seal joint supports.
Further, be provided with pin between described piston and runner hub core lead to, play the effect of transmitting torque.
The advantage that the utility model has and good effect are: the utility model adopts technique scheme, recover Axial and radial and be subject to the spacing of axle sleeve and seal joint, axle sleeve and seal joint can suitably adjust when mounted, oil pipe seat and servomotor cylinder cap disalignment can be made up, cause recovering axle hair fastener and being subject to torsional moment and being twisted off, snap ring also plays the effect of axial limiting simultaneously.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model.
Wherein: 1, servomotor cylinder 2, bolt 3, piston 4, servomotor cylinder cap
5, piston snap ring 6, axle sleeve 7, oil pipe seat 8, runner hub core
9, pin 10, snap ring 11, seal joint 12, recovery axle
Embodiment
Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.
A kind of hydraulic turbine recovers axle and runner coupling arrangement as shown in Figure 1, it is characterized in that: comprise servomotor cylinder 1, bolt 2, piston 3, servomotor cylinder cap 4, piston snap ring 5, axle sleeve 6, oil pipe seat 7, runner hub core 8, pin 9, snap ring 10, seal joint 11 and recovery axle 12, described servomotor cylinder 1 and servomotor cylinder cap 4 pass through bolt 2 closing, described piston 3 and runner hub core 8 are clamped by piston snap ring 5, by pin 9 transmitting torque, described runner hub core 8 and oil pipe seat 7 pass through bolt 2 closing, described axle sleeve 6 and oil pipe seat 7 interference fit, described snap ring 10 and servomotor cylinder cap 4 pass through bolt 2 closing, described seal joint 11 is compressed by servomotor cylinder cap 4 and snap ring 10, described recovery axle 12 is blocked by snap ring 10, play position-limiting action, described recovery axle 12 is subject to axle sleeve 6 and seal joint 11 supports.
Working method of the present utility model is: when recovering axle and moving reciprocatingly under servomotor cylinder cover strip is dynamic, and snap ring can limit its axially-movable, when recovering axle and rotating with main shaft, recovers the restriction that Axial and radial is subject to axle sleeve and seal joint; In addition, when installing recovery axle, can adjust the coaxial of it by adjustment axle sleeve and seal joint, when avoiding recovering axle motion, hair fastener is stressed.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
