The gear mechanism comprises an input shaft (1), a first gear (2), a second gear (3), a gear shaft (4), a third gear (5), a cantilever gear shaft (6), a fourth gear (7) and an output shaft (8): first gear (2) are installed on input shaft (1), second gear (3) and first gear (2) meshing, second gear (3) are installed on tooth axle (4), tooth axle (4) and cantilever tooth axle (6) are installed in the reduction gear box through tapered ball bearing (9), tooth axle (4) and third gear (5) meshing, third gear (5) are installed on cantilever tooth axle (6), cantilever tooth axle (6) and fourth gear (7) meshing, fourth gear (7) are installed on output shaft (8).
Description
Technical Field
The utility model relates to a wire rod production technical field especially relates to a reduction gear for tray elevating gear.
Background
At present, a coil collecting system of a supporting plate lifting and vertical type core winding frame is used for high-speed wires, and the coil collecting system is widely adopted due to low failure rate. The process that the coil of strip section of thick bamboo was collected will be gathered to tray elevating gear mainly accomplishes and transports vertical book core frame on, and tray elevating gear comprises motor, reduction gear, synchronizing shaft, chain and tray etc. and the rising and the decline of tray drive the reduction gear by the motor, and the reduction gear drives the transmission shaft, and the transmission shaft drives the chain, and the chain drives tray device and carries out elevating movement. The ascending process is that the no-load is braked at first fast speed and then at slow speed, the load is braked at first fast speed and then at slow speed in the descending process, and the impact generated by the larger load in the descending process is larger.
At present, a cantilever gear shaft is usually adopted in a speed reducer of a tray lifting device to reduce the volume of the speed reducer, and the cantilever shaft is positioned through a deep groove ball bearing. However, in the using process, it is found that the tray is easy to bear large impact in the descending process by adopting the deep groove ball bearing, so that the speed reducer can only bear radial load but cannot bear axial load, and therefore, the working condition of continuously bearing impact load is not suitable.
Disclosure of Invention
Adopt deep groove ball bearing to make the degree of difficulty of examining some discovery hidden danger great and the higher technical problem of maintenance cost ratio in solving present tray elevating gear's the reduction gear, the utility model provides a reduction gear for tray elevating gear.
In order to solve the technical problem, the utility model discloses a technical scheme is:
a decelerator for a tray lifting device comprising an input shaft, a first gear, a second gear, a gear shaft, a third gear, a cantilever gear shaft, a fourth gear and an output shaft, wherein: the first gear is installed on the input shaft, the second gear is meshed with the first gear, the second gear is installed on the gear shaft, the gear shaft is installed in the speed reducer box body through the conical ball bearing, the gear shaft is meshed with the third gear, the third gear is installed on the cantilever gear shaft, the cantilever gear shaft is meshed with the fourth gear, the cantilever gear shaft is installed in the speed reducer box body through the conical ball bearing, and the fourth gear is installed on the output shaft.
The utility model has the advantages that:
through setting up the pinion and cantilever pinion and installing in the reduction gear box through tapered ball bearing, adopt tapered roller bearing to fix a position pinion and cantilever pinion in the reduction gear promptly, realize on the basis that does not increase the reduction gear size, make the reduction gear can bear radial load, also can bear axial load, increased reduction gear skewed tooth constantly with higher speed and slowed down impact bearing capacity repeatedly, improved the life of reduction gear, alleviate workman's maintenance reduction gear's intensity of labour and the cost of maintaining the reduction gear simultaneously. In addition, the conical roller bearing can be judged by auscultation of the sound of the speed reducer when the bearing is abnormal and completely damaged due to the increase of the bearing capacity, so that the sudden accident that the tray falls off due to tooth beating of the speed reducer is avoided, and the potential fault is easy to find.
