Description

Technical Field

[0001] This utility model relates to the field of transmission roller technology, and in particular to a transmission roller conveyor that is impact-proof and dustproof. Background Technology

[0002] In casting production, coated sand casting is used. After the product is formed, a large amount of fine residual sand is formed on the surface of the product. During the operation of this equipment, a transmission roller conveyor is required. During use, the transmission roller conveyor will carry the fine residual sand into the bearing, causing the bearing to seize. This equipment is a tilting type that carries out the product at the same time. During the tilting process, there is a certain height point. The produced products also have a certain weight. When the casting is tilted out, when it reaches the highest point, the product slides down from the height and hits the roller conveyor of the tilting machine directly. Over time, this can easily cause the bearing's load-bearing capacity to decline and the bearing to break. The maintenance cost is high, the service life is short, and the bearing needs to be replaced on average every three days. Each replacement requires a production stoppage of about 3 hours, which seriously affects the production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the prior art by providing a transmission roller conveyor that is both dustproof and impact-resistant. This conveyor provides dust protection while also offering a certain degree of impact resistance, reducing the frequency of replacements, extending the service life of bearings, lowering maintenance costs, and increasing productivity. It is characterized by its wide applicability and strong practicality.

[0004] The technical solution adopted by this utility model is as follows: a dustproof and impact-resistant transmission roller conveyor, comprising two support shafts, a transmission shaft between the two support shafts, an installation step on the transmission shaft, two first rolling bearings on one side of the transmission shaft of the installation step, a roller on the outer ring of the first rolling bearings, an impact-resistant bearing between the two first rolling bearings, a transmission sprocket on the other side of the installation step, one end of the transmission sprocket being inserted into the roller sleeve, a second rolling bearing between the transmission sprocket and the transmission shaft, dust covers on the outer surfaces of the two first rolling bearings, the dust covers being located at the installation step, and a dust sleeve fitted onto the support shaft at the other end of the transmission sprocket.

[0005] As a further improvement, a rubber gasket is provided between the middle position of the roller and the drive shaft.

[0006] Furthermore, an anti-smashing rubber sleeve is fitted on the outer ring of the roller, and the anti-smashing rubber sleeve has multiple axially arranged buffer grooves.

[0007] Furthermore, the anti-smashing rubber sleeve is connected to the roller by multiple locking screws.

[0008] Furthermore, there is a transition fit between the transmission sprocket and the roller.

[0009] Furthermore, the support shaft is provided with a threaded hole.

[0010] Beneficial effects Compared with the prior art, this utility model has the following advantages: This utility model discloses a dustproof and impact-resistant transmission roller conveyor. By installing a dustproof sleeve on the support shaft, fine sand and dust are isolated from entering the interior. Furthermore, a dustproof cover is installed on the outside of the first rolling bearing, effectively preventing dust generated from the transmission shaft surface from entering the bearing. An impact-resistant bearing is installed inside the transmission shaft, increasing the bearing area. Additionally, rubber gaskets further increase the bearing area, providing a buffering effect. When products slide from a height and collide with the roller conveyor, this provides cushioning, thus preventing impact. This device, through its dustproof and impact-resistant functions, effectively extends bearing life, reduces maintenance costs, and increases productivity. It is highly practical and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0014] See Figs. 1-2As shown, this utility model discloses a dustproof and impact-resistant transmission roller conveyor, comprising two support shafts 1, a transmission shaft 2 between the two support shafts 1, an installation step 3 on the transmission shaft 2, two first rolling bearings 4 on one side of the transmission shaft 2, a roller 9 on the outer ring of the first rolling bearings 4, an impact-resistant bearing 5 between the two first rolling bearings 4, a transmission sprocket 6 on the other side of the installation step 3, one end of the transmission sprocket 6 being inserted into the sleeve of the roller 9, a second rolling bearing 7 between the transmission sprocket 6 and the transmission shaft 2, dust covers 12 on the outer surfaces of both first rolling bearings 4, the dust covers 12 being positioned at the installation step 3, and the other end of the transmission sprocket 6 being sleeved on the support shaft 1. The dust cover 8 on the support shaft 1 isolates fine sand and dust from entering the interior. A dust cover 12 on the outside of the first rolling bearing 4 effectively prevents dust generated from the drive shaft 2 from entering the bearing. An anti-smashing bearing 5 inside the drive shaft 2 increases the bearing area, and a rubber gasket 11 further increases the bearing area, providing cushioning when the product falls from a height and collides with the roller conveyor, thus preventing impact. This device, through its dustproof and anti-smashing functions, effectively extends bearing life, reduces maintenance costs, and increases productivity.

[0015] Specifically, a rubber washer 11 is provided between the middle position of the roller 9 and the drive shaft 2 to increase the bearing area inside the drive shaft 2. By utilizing the physical properties of rubber, the rubber washer 11 has a certain buffering effect when a heavy object hits the roller 9.

[0016] Preferably, the outer ring of the roller 9 is fitted with an anti-smashing rubber sleeve 10, and the anti-smashing rubber sleeve 10 is provided with multiple axially arranged buffer grooves 14. When a heavy object falls, the anti-smashing rubber sleeve 10 deforms using the buffer grooves 14 to buffer the impact, effectively reducing the impact force on the internal bearing and protecting the bearing.

[0017] Furthermore, the anti-smashing rubber sleeve 10 and the roller 9 are connected by multiple locking screws 13, which are used to fix the connection and serve a fixing function.

[0018] Furthermore, the drive sprocket 6 and the roller 9 are fitted with a transition fit, which allows the drive sprocket 6 to drive the roller 9 to rotate, thereby realizing the conveying. When it is necessary to convey larger objects, screws can be installed between the sprocket 6 and the drive roller 9 to increase the reliability of the connection.

[0019] Furthermore, the support shaft 1 has threaded holes 15, and both ends are rotated into the threaded holes 15 by bolts, thereby enabling the transmission rollers to be installed on the vertical plates of the conveyor belts on both sides.

[0020] This embodiment of a dustproof and impact-resistant transmission roller conveyor utilizes a dustproof sleeve 8 on the support shaft 1 to prevent fine sand and dust from entering. A dustproof cover 12 on the outside of the first rolling bearing 4 effectively prevents dust from the transmission shaft 2 from entering the bearing. An impact-resistant bearing 5 inside the transmission shaft 2 increases the bearing area, and a rubber gasket 11 further increases this area, providing cushioning when products fall from a height and collide with the roller conveyor, thus preventing impact. This device, through its dustproof and impact-resistant functions, effectively extends bearing life, reduces maintenance costs, and increases productivity. This dustproof and impact-resistant transmission roller conveyor of this invention provides both dustproof and impact-resistant properties, reducing replacement frequency, extending bearing life, lowering maintenance costs, and increasing productivity. It is characterized by its wide applicability and strong practicality.
