Description
Technical field
The utility model relates to belt pulley apparatus fields, especially with the belt pulley input unit of rock-steady structure.
Background technique
Belt pulley input unit is made of belt pulley and the installation of speed reducer input unit, and motor pulls belt pulley by belt
The operation of rotate driving speed reducer.Existing belt pulley input unit middle belt pulley is directly installed on input shaft, and electricity is worked as
Since the radial load power being subject to is excessive in machine operational process, it is easy to cause speed reducer input unit inner bearing damage and
Oil sealing oil leak.
Utility model content
Technical problem to be solved by the utility model is: in order to solve technical problem described in background technique, this is practical
It is novel to provide a kind of belt pulley input unit with rock-steady structure, by cancelling gland in input unit side, reequip axis
Seat and bearing gland are held, the radial force directly received on original bearing of input shaft is distributed on the bearing block of installation, it can be with
The spoilage and oil spill rate for greatly reducing input unit internal bearings guarantee that belt pulley input unit operates normally.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of belt pulley input unit with rock-steady structure, including input shaft, input flange, bearing gland, input shaft
Bearing, bearing block, bearing block gland, roller bearing and belt pulley are equipped with bearing of input shaft, input shaft in the input flange
Across input flange and bearing of input shaft, input flange side is fixed with bearing gland, and the input flange other side is fixed with bearing
Seat, bearing block are fixed in the interior steel ring of roller bearing, and the outer rim of roller bearing is fixed in belt pulley, bearing block gland
Bottom is fixed in bearing block.
Specifically, the deep groove ball bearing that the roller bearing is 6219.
Specifically, the roller bearing quantity is 2.
Specifically, the horizontal end face of the bearing block gland is equipped with snap ring, and snap ring is fitted on the hole inner wall of belt pulley.
The beneficial effects of the utility model are: the utility model provides a kind of belt pulley input list with rock-steady structure
Member is reequiped bearing block and bearing gland, will be directly received on original bearing of input shaft by cancelling gland in input unit side
Radial force be distributed on the bearing block of installation, can greatly reduce the spoilage and oil spill rate of input unit internal bearings,
Guarantee that belt pulley input unit operates normally.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；

4 are held, input shaft 1 passes through input flange 2 and bearing of input shaft 4, and 2 side of input flange is fixed with bearing gland 3, input flange 2
The other side is fixed with bearing block 5, and bearing block 5 is fixed in the interior steel ring of roller bearing 7, and the outer rim of roller bearing 7 is fixed on
In belt pulley 8, the bottom of bearing block gland 6 is fixed in bearing block 5.The deep groove ball bearing that the roller bearing 7 is 6219.Institute
Stating 7 quantity of roller bearing is 2.The horizontal end face of the bearing block gland 6 is equipped with snap ring 9, and snap ring 9 is fitted in belt pulley 8
Hole inner wall on.
As shown in Fig. 1, now the bearing gland at bearing on the right side of original input unit is cancelled, installation is determined by 45# material
The bearing block 5 and bearing block gland 6 of system.A pair of of roller bearing 7 is installed on bearing block 5, the model 6219 of roller bearing 7
Deep groove ball bearing, and belt pulley 8 is fixed on roller bearing 7.It can will directly receive on original bearing of input shaft 4 in this way
Radial force is distributed on the bearing block 5 of installation, can greatly reduce the spoilage and oil spill rate of input unit internal bearings, is protected
8 input unit of belt pulley is demonstrate,proved to operate normally.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
