Abstract
The utility model discloses a non-rising stem screw rod headstock gear which comprises a screw rod (1) and a gate (2). The non-rising stem screw rod headstock gear is characterized in that a nut (7) is arranged at the top of the gate (2); the screw rod (1) is matched and connected with the nut (7); the upper part of the screw rod (1) is connected with a worm wheel (4) through a coupling sleeve (5) and a locking nut (6); and one side of the worm wheel (4) is engaged with a worm rod (3). The worm rod is externally connected with a motor. When the non-rising stem screw rod headstock gear is used, the motor rotates to drive the worm rod and the worm wheel to rotate; the worm rod does rotary movement through power transmission; and the nut does straight-line movement so that the nut drives the gate to move up and down, and the opening and the closing of the gate are realized. When the non-rising stem screw rod headstock gear is operated, the screw rod is arranged in an engine body after the gate is completely lifted and the screw rod is not exposed, so that the requirements of safety and attractiven are met.
Description
Technical field
The utility model belongs to a kind of headstock gear, a kind of specifically blind rod type screw open-close machine.
Background technology
At present, in Hydraulic and Hydro-Power Engineering, screw open-close machine is the equipment that is widely used.Existing screw open-close machine all is the rising stem (RS.) formula, and it includes: open and close head, screw rod, gate, open and close head and screw rod and all be positioned on the ground, open and close the head drive screw and move up and down, the screw rod band gate and is moved up and down.Therefore, screw rod rests on above the body behind the existing screw open-close machine lift gate, and is not attractive in appearance, also dangerous when dust storm is big.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved screw open-close machine is provided, and its screw rod in body, is realized attractive in appearance and safe double effects all the time.
For reaching above-mentioned purpose; The utility model is taked following technical scheme: the utility model includes: screw rod, gate; It is characterized in that: nut is installed at the gate top; Screw rod cooperates connection with nut, screw rod top connects worm gear one side and worm engaging through coupling sleeve, lock ring locknut with worm gear.Worm screw is connected with motor outward.
The utility model is taked technique scheme; Have following beneficial effect: when the utility model used, the motor rotation drove worm screw, worm gear rotates, through transmission of power; Screw rod rotates thereupon; The nut moving linearly moves up and down thereby make the nut band gate thus, realizes the open and close of gate.The utility model is when operation, and screw rod in body, can not expose always after gate promoted fully, had satisfied safety and requirement attractive in appearance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is the structure diagram of the utility model embodiment.
Mark among the figure: 1-screw rod; The 2-gate; The 3-worm screw; The 4-worm gear; The 5-coupling sleeve; 6-lock ring locknut; The 7-nut.
The specific embodiment
By shown in Figure 1; The utility model includes: screw rod 1, gate 2 is characterized in that: at gate 2 tops nut 7 is installed, screw rod 1 cooperates connection with nut 7; Screw rod 1 top connects with worm gear 4 through coupling sleeve 5, lock ring locknut 6, worm gear 4 one sides and worm screw 3 engagements.
The coupling sleeve of the utility model connects through flat key with worm gear, and screw rod and coupling sleeve are combined into one through the locknut lock ring.
Corrosion, stuck can be caused because the nut of cast iron and copper alloy material is under water for a long time because of lacking to lubricate, gate can't be opened and closed.For addressing this problem, nut can adopt the plastic alloy material of self-lubricating, has guaranteed the operate as normal of nut and the normal keying of gate.
Claims (1)
1. blind rod type screw open-close machine; It includes: screw rod (1), gate (2); It is characterized in that: nut (7) is installed at gate (2) top; Screw rod (1) cooperates connection with nut (7), and screw rod (1) top connects with worm gear (4) through coupling sleeve (5), lock ring locknut (6), worm gear (4) one sides and worm screw (3) engagement.
