Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, specifically a transmission guide mechanism for transmission machinery. Background Technology

[0002] In the field of mechanical transmission, the transmission guide mechanism is an important component for achieving stable power transmission. It is widely used in various equipment that requires power transmission and has a key impact on the overall operating performance of the equipment. It ensures the smoothness of the power transmission process and adapts to the power transmission needs of the equipment under different working conditions.

[0003] However, in practical applications, especially under complex working conditions such as heavy loads, existing transmission guide mechanisms are affected by changes in working conditions, and the power transmission components are prone to positional deviations, affecting the accuracy and stability of power transmission. This not only reduces transmission efficiency but may also exacerbate component wear, shorten equipment lifespan, or even cause equipment failure, making it difficult to adapt well to harsh working environments such as heavy loads.

[0004] Therefore, a transmission guide mechanism for transmission machinery is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a transmission guide mechanism for transmission machinery, which has the advantages of reducing the positional deviation of power transmission components and improving transmission stability to adapt to heavy-load conditions, and solves the problem that existing mechanisms are prone to positional deviation and have poor transmission stability under heavy loads.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transmission guiding mechanism for transmission machinery, comprising a transmission mechanism, the transmission mechanism including a housing and a cover, a gear set installed inside the housing, a connecting component installed on the gear set, a limiting bracket movably installed on the connecting component, a mounting bracket provided inside the housing, the limiting bracket being positioned and installed inside the housing via the mounting bracket and guiding and limiting the gear set; the gear set including a driven gear and a driving gear, the driven gear meshing with the driving gear; the cover and the housing are connected by mounting bolts.

[0007] Preferably, the connecting assembly includes a first carriage and a second carriage, the first carriage being mounted on the driven gear and the second carriage being mounted on the driving gear.

[0008] In the design, the first slide of the connecting component is mounted on the driven gear and the second slide is mounted on the driving gear, which realizes the precise corresponding connection between the connecting component and the two gears in the gear set, and provides the basis for the connecting structure for subsequent guiding and limiting of the gears.

[0009] Preferably, the first slide and the second slide are used in conjunction with the limiting frame to guide and limit the installation position of the gear set.

[0010] In the design, the first and second slides work together with the limiting frame to guide and limit the installation position of the gear set, realizing the synergistic effect of the connecting components and the limiting frame. This enhances the pertinence and effectiveness of the position constraint on the gear set and avoids the problem of insufficient limiting by a single component.

[0011] Preferably, the cover has a first reserved hole and a second reserved hole. A first bearing is installed in the first reserved hole and a second bearing is installed in the second reserved hole. The first bearing is used to support the shaft of the driven gear and the second bearing is used to support the shaft of the driving gear.

[0012] In the design, a first bearing is installed in the first reserved hole of the cover and a second bearing is installed in the second reserved hole. The first bearing supports the shaft of the driven gear and the second bearing supports the shaft of the driving gear, which realizes the separate stable support of the two gear shafts in the gear set. It has the advantages of reducing the frictional resistance of the shaft rotation and ensuring the rotational stability of the gear set.

[0013] Preferably, a sprocket is mounted on the shaft of the driven gear, and the sprocket is used to cooperate with an external transmission chain.

[0014] In the design, a sprocket is mounted on the shaft of the driven gear, and the sprocket is used to cooperate with the external transmission chain, thus realizing the power connection between the transmission mechanism and the external transmission components.

[0015] Preferably, a drive mechanism is connected to the transmission mechanism, and the transmission end of the drive mechanism is connected to the shaft of the drive gear to provide power input to the transmission mechanism.

[0016] In the design, the transmission mechanism is connected to the drive mechanism, and the transmission end of the drive mechanism is connected to the shaft of the drive gear. This enables the drive gear to receive a continuous and stable power input, ensuring the initial power reliability of the gear set meshing transmission and the normal operation of the entire transmission guide mechanism.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model achieves the effect of reducing the positional deviation of power transmission components and improving transmission stability to adapt to heavy-load working conditions by setting up a gear set, connecting component, limiting bracket, mounting bracket and the connection structure between cover and shell in the transmission mechanism.

[0019] Gear sets consist of driven gears and driving gears that mesh with each other. As core power transmission components, the meshing accuracy of these two gears directly affects the transmission stability.

[0020] By installing a connecting component on the gear set and movably installing a limiting bracket on the connecting component, while using a mounting bracket set inside the housing to position and install the limiting bracket, the limiting bracket can provide a stable guiding and limiting effect on the gear set.

[0021] Under heavy load conditions, when the driven gear or the driving gear has a tendency to shift position, the limit frame can constrain it through the connecting components, effectively reducing the positional deviation between the two.

[0022] In addition, the cover and the housing are connected by mounting bolts, which can ensure the overall stability of the internal structure of the transmission mechanism under heavy load, avoid the gear position deviation caused by structural loosening, and further improve the transmission stability. This solves the problem that the existing mechanism is prone to position deviation of power transmission components and poor transmission stability under heavy load. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one embodiment of this utility model is provided: a transmission guide mechanism for transmission machinery, including a transmission mechanism 1. The transmission mechanism 1 includes a housing 11 and a cover 15. An installation frame 111 is integrally formed on the inner wall of the housing 11. A gear set 14 is installed inside the housing 11. The gear set 14 includes a driven gear 141 and a driving gear 142. Both the driven gear 141 and the driving gear 142 are rotatably disposed in the housing 11 through a rotating shaft, and the driven gear 141 and the driving gear 142 are meshed and connected to realize power transmission.

[0031] A connecting assembly 13 is installed on the gear set 14. The connecting assembly 13 includes a first slide 131 and a second slide 132. The first slide 131 is fixedly installed on the hub end face of the driven gear 141 by internal hex bolts. The second slide 132 is fixedly installed on the hub end face of the driving gear 142 by internal hex bolts of the same specification. Both the first slide 131 and the second slide 132 have annular guide grooves on the side away from the gear hub.

[0032] A limiting frame 12 is movably installed on the connecting assembly 13. One side of the limiting frame 12 extends into the guide groove of the first slide 131 and the second slide 132, and a sliding sleeve made of polytetrafluoroethylene can be fitted onto the end of the limiting frame 12 that extends into the guide groove. The sliding sleeve can slide and cooperate with the inner wall of the guide groove.

[0033] The limiting frame 12 is adapted to the mounting frame 111 with clearance fit and is positioned and installed in the housing 11. The first slide 131 and the second slide 132 are slidably fitted with the limiting frame 12 through guide grooves to guide and limit the installation position of the gear set 14.

[0034] The cover 15 of the transmission mechanism 1 is a plate-shaped structure adapted to the opening of the housing 11. A first reserved hole 151 is provided on the cover 15 at the position corresponding to the shaft of the driven gear 141, and a second reserved hole 152 is provided at the position corresponding to the shaft of the driving gear 142. A first bearing 153 is interference-fitted in the first reserved hole 151, and a second bearing 154 is interference-fitted in the second reserved hole 152. The inner ring of the first bearing 153 is interference-fitted with the shaft of the driven gear 141 to provide radial and axial support for the shaft of the driven gear 141. The inner ring of the second bearing 154 is interference-fitted with the shaft of the driving gear 142 to provide radial and axial support for the shaft of the driving gear 142.

[0035] The driven gear 141 has one end of its shaft away from the gear body that passes through the inner ring of the first bearing 153 and is connected to the inner hole of the sprocket 16 by a flat key. The outer circumference of the sprocket 16 is provided with tooth grooves that are adapted to the external transmission chain, so as to cooperate with the external transmission chain to realize multi-path power transmission.

[0036] The edge of the cover 15 is evenly provided with three bolt holes along the circumference, and the edge of the opening of the housing 11 is provided with the same number of threaded holes. The cover 15 is threadedly connected to the threaded holes of the housing 11 by three mounting bolts 17 passing through the bolt holes, so as to ensure the sealing of the internal structure of the transmission mechanism 1 and prevent external dust and impurities from entering and affecting gear meshing.

[0037] The transmission mechanism 1 is connected to the drive mechanism 2, which is a servo motor or a hydraulic motor. Its transmission end is connected to the end of the shaft of the drive gear 142 away from the gear body via a flat key, which is used to provide stable power input to the transmission mechanism 1. The part where the shaft of the drive gear 142 is connected to the transmission end of the drive mechanism 2 is also fitted with an elastic coupling, which is used to buffer the instantaneous impact force when the drive mechanism 2 starts.

[0038] When this utility model is in use, after the drive mechanism 2 is started, its transmission end buffers the instantaneous impact through the elastic coupling and transmits the power to the rotating shaft of the drive gear 142. The drive gear 142 transmits the power to the driven gear 141 through meshing with the driven gear 141. The rotating shaft of the driven gear 141 then cooperates with the external transmission chain through the sprocket 16 to realize the multi-path output of power.

[0039] During this process, if the heavy load causes the driving gear 142 or driven gear 141 to have a radial or axial offset tendency, the first slide 131 and the second slide 132 on the gear set 14 will have an offset tendency synchronously with the gear. The limiting frame 12 is fixed in the housing 11 by the mounting frame 111. The guide grooves of the first slide 131 and the second slide 132 will slide slightly along the sliding sleeve at the end of the limiting frame 12. At the same time, the limiting frame 12 constrains the sliding range of the slide to prevent the gear offset from exceeding the meshing allowable range, thereby preventing gear meshing misalignment.

[0040] The first bearing 153 and the second bearing 154 on the cover 15 support the shafts of the driven gear 141 and the driving gear 142 respectively, reducing the frictional resistance when the shafts rotate and limiting the radial runout of the shafts, thus ensuring the rotational stability of the gears. The mounting bolts 17 are evenly distributed along the edge of the cover 15 to ensure that the housing 11 and the cover 15 are firmly connected, preventing the housing 11 and the cover 15 from loosening under heavy load conditions, which would cause displacement of the internal structure. This ensures that the transmission guide mechanism can still operate stably under harsh conditions such as heavy load and impact.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
