Description

Technical Field

[0001] This utility model relates to the technical field of lead screw transmission structures, and specifically to an integrated lead screw transmission module. Background Technology

[0002] In transmission structures, the most common type is the lead screw drive, sometimes also referred to as a lead screw assembly. In the prior art, Chinese patent application number CN202421656739.3 provides a double-nut ball screw, relating to the field of double-nut ball screw technology. It includes a first nut and a second nut, with an installation mechanism between them. The installation mechanism includes two sets of placement slots, each set containing a placement block. A strap is placed between the grooves of two placement blocks, and an elastic card is placed between the two slots. Two fixing blocks are fixed to the surface of the elastic card. This invention, by setting up an installation mechanism, allows for quick assembly and disassembly of the two nuts in the double-nut ball screw.

[0003] This type of ball screw, as a transmission structure, lacks stability. It is also not equipped with a drive motor and requires the use of linear guides. When paired with linear guides, it is relatively large. Moreover, the motor is usually installed at the end of the screw to drive the screw to rotate, so that the nut can move forward or backward. The nut is the driven part, and the two ends of the screw are fixed installation parts. This transmission module structure, with linear guides and motors, has a large overall size and is not convenient for use in narrow installation environments.

[0004] To facilitate the integration of the motor into the lead screw drive for easy installation and use, a new structure needs to be redesigned. Utility Model Content

[0005] To address the technical problems and shortcomings of existing technologies, this invention provides an integrated lead screw drive module that overcomes the technical problems of traditional lead screw drive structures where the motor and linear guide need to be matched and installation is cumbersome, and components are scattered. This module aims to achieve compact motor installation, ease of installation and use, and stable and reliable operation.

[0006] To achieve the above and other related objectives, the present invention adopts the following technical solution:

[0007] An integrated lead screw drive module includes an end seat, a lead screw, a stabilizer bar, a housing, a sliding sleeve, a nut, and a speed control driver. The ends of the lead screw and the stabilizer bar, which are parallel and in the same direction, are fixed on the end seat. The sliding sleeve is sleeved on the stabilizer bar and fixed on the housing, sliding and moving with the stabilizer bar. The nut is rotatably connected to the housing and sleeved on the lead screw for transmission. A driven gear is provided on the nut. The drive gear on the speed control driver meshes with the driven gear. The nut is driven to rotate by the speed control driver, which is installed inside the housing.

[0008] Preferably, the nut is mounted on one side of the housing via a bearing, with a portion of the nut inside the housing and a portion outside the housing, and the driven gear is fixed to the outer end of the nut outside the housing.

[0009] Preferably, the speed-regulating drive includes a motor, a coupling, and a drive gear. The motor and coupling are housed in a housing. The coupling is connected to the housing via another bearing and is connected to the drive gear.

[0010] Preferably, the housing is provided with an oil tank, an oil pump, and a nozzle. The oil pump is used to provide power to supply the lubricating oil in the oil tank to the nozzle. The nozzle has outlets in at least two directions and is installed between the stabilizer bar and the lead screw.

[0011] Preferably, the box body is provided with a partition, which divides the cavity inside the box body to form at least one partition cavity.

[0012] Preferably, the lead screw and the stabilizer are located in the same partition chamber, and the speed control driver is located in another partition chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Compared with the ball screw transmission method of traditional transmission, this utility model integrates a speed control driver, a stabilizer bar, and a housing. The housing integrates the nut and the sliding sleeve together, and the speed control driver uses gear transmission to realize the rotational movement of the nut, thereby driving the entire housing forward and backward on the ball screw. This is the opposite of the ball screw transmission method where the rotation of the ball screw is the active force and the nut is the passive force. The innovation of this solution enables the speed control driver to be integrated and moved on the housing, increasing the overall load-bearing capacity of the housing and thus improving the smoothness of movement. The stabilizer bar not only provides support for the housing but also provides guidance, making the movement of the housing stable and reliable.

[0015] 2. In this utility model, the housing can protect the nuts and sliding sleeves, and also facilitates the installation of other components on the housing.

[0016] 3. This utility model utilizes an oil tank and oil pump inside the housing to provide lubricating oil. The lubricating oil can be added to the lead screw and stabilizer bar, thereby reducing their friction and wear and extending their service life. In addition, a partition is used for spatial isolation, so that the lubricating oil can be isolated in one space and can be effectively recycled, allowing for repeated lubrication of the lead screw and stabilizer bar.

[0017] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0029] Example 1:

[0030] This invention discloses an integrated lead screw 2 transmission module, as per an embodiment of the invention. Figure 1 , Figure 2 , Figure 3 and Figure 4 The components include end seat 1, lead screw 2, stabilizer bar 3, housing 4, sliding sleeve 5, nut 6, and speed control drive 7. (This is achieved through...) Figure 4 In this design, the parallel and unidirectional ends of the lead screw 2 and stabilizer bar 3 are fixed to end seats 1. This design makes the installation of the lead screw 2 and stabilizer bar 3 very easy; they can be used directly by installing the end seats 1. In practice, there can be two end seats 1, located at both ends of the lead screw 2. The lead screw 2, stabilizer bar 3, and end seats 1 are fixed in place and remain stationary.

[0031] Figure 4 In the middle, the sliding sleeve 5 is sleeved on the stabilizer bar 3 and fixed on the housing 4, and slides with the stabilizer bar 3. The sliding cooperation between the stabilizer bar 3 and the sliding sleeve 5 not only provides support for the housing 4, but also provides guidance for the stable movement of the housing 4, thereby improving the linear motion accuracy of the housing 4.

[0032] Nut 6 is rotatably connected to housing 4 and sleeved onto lead screw 2 for transmission. Nut 6 is equipped with driven gear 8, and drive gear 71 on speed controller 7 meshes with driven gear 8. Nut 6 is driven to rotate by speed controller 7, which is installed inside housing 4. Speed ​​controller 7 can be a gearbox with motor 72, servo motor 72, etc.

[0033] Specifically, in this embodiment, the nut 6 is mounted on one side of the housing 4 via a bearing 9. A portion of the nut 6 is inside the housing 4, and a portion is outside the housing 4. The driven gear 8 is fixed to the outer end of the nut 6 outside the housing 4. This structure improves transmission stability, and the stability of the connection between the nut 6 and the lead screw 2 is enhanced by the increased length of the nut 6. The portion of the nut 6 inside the housing 4 is protected by the housing 4, preventing impact.

[0034] In a specific example, the speed control drive 7 includes a motor 72, a coupling 73, and a drive gear 71. The motor 72 and the coupling 73 are located inside the housing 4. The coupling 73 is connected to the housing 4 and the drive gear 71 via another bearing 9.

[0035] Example 2:

[0036] Combination Figure 4 and Figure 5 Based on Embodiment 1, this solution includes an oil tank 10, an oil pump 11, and a nozzle 12 within the housing 4. The oil pump 11 provides power to supply lubricating oil from the oil tank 10 to the nozzle 12. The nozzle 12 has outlets in at least two directions and is installed between the stabilizer bar 3 and the lead screw 2. This allows the nozzle 12 to simultaneously lubricate both the stabilizer bar 3 and the lead screw 2. A partition 13 is provided within the housing 4, dividing the cavities within the housing 4 to form at least one partitioned chamber. The lead screw 2 and stabilizer bar 3 are located in the same partitioned chamber, while the speed control drive 7 is located in another partitioned chamber. The oil tank 10 and oil pump 11 within the housing 4 provide lubricating oil, which can be added to the lead screw 2 and stabilizer bar 3, thereby reducing friction and wear and extending their service life. Furthermore, the partition 13 provides spatial isolation, allowing the lubricating oil to be isolated within a single space and effectively recycled for repeated lubrication of the lead screw 2 and stabilizer bar 3.
