Abstract
The utility model relates to a reverse hang type screw rod headstock gear, an organic whole is made with gate nut permanent seat (3) in gate (2), joint bearing (4) location is on nut permanent seat (3), and fix on nut permanent seat (3) through joint bearing location end cover (5) and screw (6), transmission nut (8) location is on joint bearing (4), fix on joint bearing (4) through lock nut (7), a screw pair is constituteed with transmission nut (8) in drive screw (9), during the transmission, rotate drive screw (9), transmission nut (8) stimulate gate (2) positive and negative motion together along drive screw's (9) axial lead direction. But its automatically regulated center can automatic alignment during the installation, the user of being convenient for uses and maintain that make things convenient for safe and reliable, the screw rod does not go up and down along with the gate.
Description
Technical field
This utility model relates to a kind of reversely hung Yong screw open-close machine.
Background technology
Existing worm-type open-close machine, is that one screw rod is connected with lock gate leaf directly or by guide runner, connecting rod, and screw rod moves up and down the machinery with open-close sluice gate.Gate opening/closing along with extensively carrying out of Hydraulic and Hydro-Power Engineering, in the engineering projects such as worm-type open-close machine is largely used to river course, Reservoir-irrigated District dykes and dams, Hydraulic power station.
During installation, basis plane of arrangement level 180 ° must be kept；Headstock gear base to reach more than 90% with the contact area of basis plane of arrangement；The horizontal plane of screw axis lock to be perpendicular to platform entablature；To coincide vertical with gate lifting eye hole, it is to avoid screw rod tilts, and causes stress raisers to damage parts.
The most common screw open-close machine proposes a lot of requirements to its installation and debugging, and install and be difficult to centering, and fault is the most disposable in follow-up use with maintenance process, screw rod is with gate one lifting, therefore at present worm-type open-close machine is had and operate steadily and be easily installed and the user of maintenance requirement, and require screw rod not with gate one lifting, cannot meet and require that.
Summary of the invention
The purpose of this utility model: a kind of reversely hung Yong screw open-close machine of design, can be automatically adjusted center, during installation can automatic capturing, user-friendly with safeguard, and screw rod is not with gate one lifting.
This utility model solves its technical problem and be the technical scheme is that
Gate is fixed seat with gate nut and is made of one.
Oscillating bearing is positioned at nut and fixes on seat, and is fixed on nut is fixed on seat by oscillating bearing location end cap and screw.
Transmission nut is positioned on oscillating bearing, and is fixed on oscillating bearing by locking nut.
Drive screw forms a screw pair with transmission nut, and during transmission, drive screw rotates, and transmission nut pulls gate positive counter-movement together along the direction of axis line of drive screw, and by oscillating bearing automatic aligning.
Center can be automatically adjusted, during installation can automatic capturing, user-friendly with safeguard, convenient and safe reliably, screw rod is not with gate one lifting
Below in conjunction with Figure of description, this utility model is described in detail.
Accompanying drawing explanation
Accompanying drawing 1: the structure chart of a kind of reversely hung Yong screw open-close machine
In accompanying drawing: 1 concrete doorframe, 2 gates, 3 gate nuts fix seat, 4 oscillating bearings, 5 oscillating bearing location end caps, 6 screws, 7 locking nuts, 8 transmission nuts, 9 drive screws, 10 screw machine casings, 11 plane bearings one, 12 power input gears, 13 flat keys, 14 plane bearings, 15 washer 16 wheel gear locking nuts, 17 end caps, 18 end caps fix screw, 19 foundation bolts, 20 anchor nuts.
Detailed description of the invention
In description shown in accompanying drawing 1: gate nut is fixed seat 3 and is made of one with gate 2.
In description shown in accompanying drawing 1: oscillating bearing 4 is fixed on gate 2 by oscillating bearing location end cap 5 and multiple screw 6.
In description shown in accompanying drawing 1: 7 transmission nuts 8 of locking nut are fixed on oscillating bearing 4.
In description shown in accompanying drawing 1: gate 2 is positioned in concrete doorframe 1, can lift in concrete doorframe 1.
In description shown in accompanying drawing 1: drive screw 9 and transmission nut 8 drving sprial that partners is secondary.
In description shown in accompanying drawing 1: power input gear 12 is fixed on drive screw 9 by flat key 13 and two wheel gear locking nuts 16.
In description shown in accompanying drawing 1: plane bearing 1 is positioned on screw machine casing 10 and drive screw 9 by power input gear 12.
In description shown in accompanying drawing 1: washer 15 is disposed axially between plane bearing 14 and wheel gear locking nut 16, play the effect of power transmission.
In description shown in accompanying drawing 1: end cap 17 and multiple end cap are fixed screw 18 and be positioned on drive screw 9 and end cap 17 by plane bearing 14.
In description shown in accompanying drawing 1: end cap 17 is fixed screw 18 by multiple end caps and is positioned on 10.
In description shown in accompanying drawing 1: screw machine casing 10 location is fixed on concrete doorframe 1 by multiple foundation bolts 19 and anchor nut 20.
In description shown in accompanying drawing 1: during open-close sluice gate 2, drive screw 9 produces rotary motion, transmission nut 8 does not rotates, and moves with gate 2, and drive screw 9 does not moves with gate 2.
A kind of reversely hung Yong screw open-close machine work process: power from power input gear 12 inputs, drive screw 9 is imparted power to through flat key 13, drive screw 9 produces rotary motion, fix seat 3 by gate nut, oscillating bearing 4, oscillating bearing location end cap 5, screw 6, locking nut 7, transmission nut 8 pull gate 2 to move in the gate slot of concrete doorframe 1, transmission nut 8 does not rotates, move with gate 2, when opening gate 2, drive screw 9 rotates forward, and plane bearing 1 carries Qi Menli by screw machine casing 10;During closing gate 2,9 reversions, the most on earth time, plane bearing 1 carries Qi Menli by screw machine casing 10, close door on earth time plane bearing 14 by end cap 17 carry upwards close a power, complete the opening-closing process of a kind of reversely hung Yong screw open-close machine, a kind of reversely hung Yong screw open-close machine is reasonable in design, novel structure, can be used in the machinery having open-close sluice gate of various working.
