Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a top flow machine, and more particularly to a top flow machine gearbox. Background Technology

[0002] A buoyancy booster, also known as a positioning thruster, is a device used to control the position of a ship. It generates thrust in different directions by jetting high-pressure water to adjust the ship's position and orientation, preventing it from drifting or drifting too fast.

[0003] Existing top-flow propeller structures, such as the steering structure of a marine propeller disclosed in the Chinese Patent Database (application number: 202422674799.4), include a support for fixing to the hull, a steering shaft that runs vertically through the support and is rotatable, and a steering device that drives the steering shaft to rotate is installed above the support. The steering device includes a support housing and an automatic steering assembly disposed within the support housing. The automatic steering assembly includes a steering motor, a transmission gear set connecting the steering motor and the steering shaft, and a remote control module for controlling the steering motor. A handle is installed on one side of the bracket housing. A first hollow tube, which is fitted over the steering shaft and can rotate relative to it, is fixedly installed under the bracket housing. A second hollow tube, which can fit over the first hollow tube, is provided on the support. A locking device is provided on the support to fix the relative position of the second hollow tube and the first hollow tube. When the locking device fixes the relative position of the first hollow tube and the second hollow tube, the steering motor runs and is in automatic steering mode. When the locking device is released, the first hollow tube and the second hollow tube are in a state where they can rotate relative to each other, and the steering can be controlled by the handle.

[0004] The aforementioned propulsion system uses a steering assembly to drive a steering shaft to rotate, thereby changing the direction of the propulsion device mounted below the steering shaft and suspending the vessel at a set position. When the vessel needs to continue moving, the steering shaft must be manually rotated by pressing a remote control to return the propulsion device to its original position, which is inconvenient. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a conveniently controllable top flow machine gearbox.

[0006] The objective of this utility model can be achieved through the following technical solution: A top-flow machine gearbox includes a housing and an output shaft vertically rotatably disposed within the housing. The housing wall is provided with a wire outlet hole. The output shaft is hollow, with its upper end extending out of the housing. A motor is fixed inside the housing and disposed on one side of the output shaft. The motor drives the output shaft to rotate through a gear reduction mechanism. The key feature is that a magnetic encoder is also fixed inside the housing and disposed on the other side of the output shaft. The magnetic encoder includes a vertically disposed rotating shaft with a driven gear coaxial with the rotating shaft. A driving gear matching the driven gear is sleeved and fixed on the output shaft, and the driving gear and the driven gear mesh with each other.

[0007] In use, both the magnetic encoder and the motor are electrically connected to the top flow machine controller located outside the housing via wires. The magnetic encoder records the rotation angle of the output shaft through the cooperation of the drive gear and the driven gear, so that the output shaft can be automatically returned to center by driving the motor through the controller. This eliminates the need to manually drive the output shaft to center through the remote control, which has the advantages of being convenient and easy to use.

[0008] In the aforementioned top-flow machine gearbox, the top-flow machine includes a long, narrow base, and the gearbox is installed on the front side of the base. The gearbox is long and extends from front to back. The motor, gear reduction mechanism, output shaft, and magnetic encoder are distributed sequentially along the length of the gearbox, so that the gearbox can be designed to be narrower, thereby reducing the horizontal area occupied by the top-flow machine.

[0009] In the aforementioned top-flow machine gearbox, the gear reduction mechanism includes an input gear sleeved on the output shaft, and both the input gear and the drive gear are circumferentially fixed to the output shaft using splines or flat keys; the output shaft is also provided with a limiting structure, which simultaneously limits the input gear and the drive gear in the axial direction, thereby reducing the input of parts and making the whole structure simpler, with advantages such as simple structure and convenient installation.

[0010] In the aforementioned top-flow machine gearbox, the driving gear is pressed against the top surface of the input gear; the limiting structure includes two annular limiting members, both of which are sleeved and fixed on the output shaft, and the top surface of the driving gear and the bottom surface of the input gear are pressed against the two limiting members respectively.

[0011] In the aforementioned top-flow machine gearbox, two annular grooves are provided on the outer wall of the output shaft, and the limiting component is a snap ring installed in the annular groove.

[0012] As an alternative, in the aforementioned top-flow machine gearbox, the limiting component is a pressure ring, and the pressure ring is threadedly connected to the output shaft.

[0013] In the aforementioned top-flow machine gearbox, a handle is fixed to the front end of the housing. In the actual product, the rear end of the housing is hinged to the base via a horizontal shaft, and a handle is provided to facilitate the operation of rotating the housing around the horizontal shaft, thereby enabling the top-flow machine to fold and unfold.

[0014] In the aforementioned top-flow machine gearbox, the housing includes a long, narrow box-shaped main body, within which the motor, gear reduction mechanism, and output shaft are all housed. The front end of the box-shaped main body extends forward to form a mounting cavity for accommodating the magnetic encoder. The rear side of the mounting cavity is open and connects to the inner cavity of the box-shaped main body. A receiving area is formed between the bottom wall of the mounting cavity and the front end face of the box-shaped main body. The front end of the handle extends into this receiving area and is fixed to the box-shaped main body. The handle front end is positioned within the receiving area formed by the mounting cavity and the box-shaped main body, allowing the handle and housing to partially overlap, reducing the overall length of the gearbox and minimizing space occupation.

[0015] In the aforementioned top-flow machine gearbox, the handle consists of a grip portion roughly in the shape of a "7" and a connecting block horizontally formed at the front end of the grip portion. The connecting block extends horizontally and is pressed against and fixed to the front end face of the main body of the box to improve the positioning strength and reliability of the handle.

[0016] In the aforementioned top flow machine gearbox, both ends of the connecting block are fixed to the main body of the box shape by screws.

[0017] Compared with existing technologies, the gearbox of this top-flow machine has the following advantages: 1. During use, the magnetic encoder and motor are both electrically connected to the top flow machine controller located outside the housing via wires. The magnetic encoder records the rotation angle of the output shaft through the cooperation of the drive gear and the driven gear, so that the output shaft can be automatically returned to the center by driving the motor through the controller. This eliminates the need to manually drive the output shaft to return to the center via the remote control, which has the advantages of being convenient and easy to use.

[0018] 2. The front end of the handle is set in the receiving area composed of the mounting cavity and the box-shaped body, so that the handle and the box body partially overlap, reducing the overall length of the gearbox and reducing space occupation. Attached Figure Description

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] Example 1: As Figures 1 to 4 As shown, the gearbox of this top-flow machine includes a housing 1 and an output shaft 2 vertically rotatably mounted inside the housing 1, and the output shaft 2 is hollow. The housing 1 consists of a lower housing with an open top and an upper cover 1a covering the lower housing, and the upper cover 1a and the lower housing are fixed together by a ring of bolts. Both the bottom of the lower housing and the top of the upper cover 1a have through holes. The upper end of the output shaft 2 extends out of the housing 1 through the through hole in the upper cover 1a, and the lower end of the output shaft 2 is inserted into the through hole in the lower housing. Bearings 3, preferably ball bearings, are installed in both through holes to create a rotational fit between the output shaft 2 and the housing 1. Further, oil seals 4 are also provided in the two through holes to create a seal between the output shaft 2 and the housing 1. In this case, both bearings 3 are positioned between the two oil seals 4.

[0027] Specifically The enclosure 1 has a cable outlet hole on its wall, and preferably the cable outlet hole is located on the side wall of the lower enclosure. For example... Figure 4 and Figure 5 As shown, a motor 5 is fixed inside the housing 1, and the rotor shaft of the motor 5 is vertically arranged. In the actual product, the motor 5 is fixedly connected to the housing 1 via a base. The motor 5 is located on one side of the output shaft 2, and the motor 5 drives the output shaft 2 to rotate through a gear reduction mechanism. A magnetic encoder 6 is also fixed inside the housing 1, and the magnetic encoder 6 is located on the other side of the output shaft 2. The magnetic encoder 6 is an existing product with a readily available structure, which can be customized or purchased from the market; its structure will not be described in detail here. The magnetic encoder 6 includes a vertically arranged rotating shaft 6a, on which a driven gear 6b ​​is coaxial. A driving gear 7, matching the driven gear 6b, is sleeved and fixed on the output shaft 2, and the driving gear 7 and the driven gear 6b ​​mesh. Preferably, the driven gear 6b ​​and the rotating shaft 6a are an integral structure.

[0028] In use, the wires of the magnetic encoder 6 and the motor 5 extend out of the housing 1 through the wire outlet hole. The extended wires are electrically connected to the top flow machine controller located outside the housing 1. The magnetic encoder 6 records the rotation angle of the output shaft 2 through the cooperation of the driving gear 7 and the driven gear 6b, so that the output shaft 2 can be automatically returned to the center by driving the motor 5 through the controller. This eliminates the need to manually drive the output shaft 2 to return to the center through the remote control, which has the advantages of being convenient and easy to use.

[0029] To further explain, the top flow machine includes a long strip-shaped base 8, and a housing 1 is installed on the front side of the base 8; the housing 1 is strip-shaped and extends front and back, and the motor 5, gear reduction mechanism, output shaft 2 and magnetic encoder 6 are distributed in sequence along the length of the housing 1, so that the gearbox can be designed to be narrower, thereby reducing the horizontal area occupied by the top flow machine.

[0030] In this embodiment, like Figure 4 and Figure 5 As shown, the gear reduction mechanism includes a drive pinion 11 fixed on the rotor shaft of the motor 5, an input gear 9 sleeved and fixed on the output shaft 2, and a three-stage reduction structure disposed between the drive pinion 11 and the input gear 9. This three-stage reduction structure includes three gear shafts 10, which are vertically rotatable within the housing 1. Large and small gears are formed on the gear shafts 10, with the large gear positioned below the small gear. Specifically, the large gear on the first gear shaft 10 meshes with the drive pinion 11, the small gear on the last gear shaft 10 meshes with the input gear 9, the large gear on the middle gear shaft 10 meshes with the small gear on the first gear shaft 10, and the small gear on the middle gear shaft 10 meshes with the large gear on the last gear shaft 10.

[0031] The installation method of the input gear 9 and the driving gear 7 is as follows: Both the input gear 9 and the driving gear 7 are circumferentially fixed to the output shaft 2 using splines or flat keys, and preferably both the input gear 9 and the driving gear 7 are circumferentially fixed to the output shaft 2 using splines. The output shaft 2 is also provided with a limiting structure, which simultaneously limits the input gear 9 and the driving gear 7 in the axial direction, thereby reducing the number of parts required and making the entire structure simpler. It has the advantages of simple structure and convenient installation.

[0032] The driving gear 7 is pressed against the top surface of the input gear 9. The limiting structure includes two annular limiting members 12, both of which are sleeved and fixed on the output shaft 2. The top surface of the driving gear 7 and the bottom surface of the input gear 9 are pressed against the two limiting members 12 respectively. In the actual product, two annular grooves are formed on the outer wall of the output shaft 2. The annular grooves are coaxially arranged with the output shaft 2, and the limiting members 12 are snap rings installed in the annular grooves.

[0033] like Figures 1 to 3As shown, a handle 13 is fixed at the front end of the housing 1. In the actual product, the rear end of the housing 1 is hinged to the base 8 via a horizontal shaft 14, and the horizontal shaft 14 extends to the left and right. The handle 13 is provided to facilitate the operation of the housing 1 to rotate around the horizontal shaft 14, thereby realizing the folding and unfolding of the top flow machine.

[0034] in, The specific installation method of handle 13 is as follows: The housing 1 includes a long, narrow box-shaped body 1b, and the length of the box-shaped body 1b extends front to back. The motor 5, the gear reduction mechanism, and the output shaft 2 are all housed inside the box-shaped body 1b. The front end of the box-shaped body 1b extends forward to form a mounting cavity 1c for accommodating the magnetic encoder 6. The rear side of the mounting cavity 1c is open and connects to the inner cavity of the box-shaped body 1b. The bottom wall of the mounting cavity 1c and the front end face of the box-shaped body 1b form a receiving area 1d. The front end of handle 13 extends into the receiving area 1d and is fixed to the box-shaped body 1b. The front end of handle 13 is positioned in the receiving area 1d formed by the mounting cavity 1c and the box-shaped body 1b, so that handle 13 and housing 1 partially overlap, reducing the overall length of the gearbox and reducing space occupation.

[0035] To further explain, the handle 13 is a one-piece structure, and preferably a one-piece plastic component. The handle 13 consists of a grip portion 13a, roughly in the shape of a "7", and a connecting block 13b horizontally formed at the front end of the grip portion 13a. The connecting block 13b extends horizontally and presses against and fixes itself to the front end face of the box-shaped body 1b to improve the positioning strength and reliability of the handle 13. Preferably, both ends of the connecting block 13b are fixed to the box-shaped body 1b by screws.

[0036] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference is that the limiting member 12 is a pressure ring, and the pressure ring and the output shaft 2 are threaded together.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
