Abstract
A speed reducer comprises a high-speed shaft and an intermediate shaft, wherein the high-speed shaft is connected with the intermediate shaft via an intermediate gear. The speed reducer is characterized in that springs are respectively arranged among teeth of the intermediate gear. The springs arranged among the teeth of the intermediate gear can buffer impact on the teeth, thereby solving the problem of unbalanced load in tooth meshing due to error of processing assembly, strengthening bearing capacity of the intermediate gear, and not only prolonging service life of the speed reducer but reducing noise.
Description
Technical field
The utility model relates to the lift that is applied to colliery, metallic ore, nonmetallic ore etc., relates in particular to a kind of retarder.
Background technique
Retarder is an enclosed transmission device independently between motor and the main shaft of hoister device, be used for reducing rotating speed and increase torque, existing retarder adopts conventional type of belt drive, can occur because Gear Processing and assembly error cause the unbalanced phenomenon of load when a tooth meshes, not only noise is bigger, and causes gear to damage easily.
The model utility content
The purpose of this utility model is to provide a kind of flimsy retarder of not allowing.
The purpose of this utility model is achieved in that a kind of retarder, comprises high speed shaft and jack shaft, and described high speed shaft is connected by intermediate gear with jack shaft, it is characterized in that: be provided with spring between the gear teeth of described intermediate gear.
For compact structure, reliable operation, above-mentioned spring is arranged between the described adjacent gear teeth by spring seat.
The above-mentioned gear teeth comprise the revolver tooth and the right gear teeth that are oppositely arranged, and the described revolver tooth and the right gear teeth are installed in the wheel tube that is provided with on the above-mentioned intermediate gear.
Be provided with dividing plate between the above-mentioned revolver tooth and the right gear teeth and pass through bolt, nuts and washers connection.
The utility model has following beneficial effect, the utility model is by being provided with spring between the gear teeth of intermediate gear, can cushion the impact force that the gear teeth are subjected to, the unbalanced problem of load during the individual tooth engagement that solved that error owing to processing and assembling causes, strengthened the bearing capacity of intermediate gear, not only prolong the working life of retarder, and reduced noise.
