Abstract
The invention relates to a gear train device convenient to mount and replace. The gear train device comprises a rope sheave, a rope sheave shaft and a rope sheave shaft fixing rack, wherein the rope sheave shaft is a stepless shaft; two bearings arranged in parallel are assembled between the rope sheave and the rope sheave shaft; a hollow cavity between the two bearings forms an oil cavity; an oil filling nozzle which is communicated with the oil cavity is arranged on the rope sheave; snap springs fixed on the rope sheave are arranged on adjacent end surfaces of both of the two bearings; the snap springs are attached to outer end surfaces of the bearings; the rope sheave shaft is sleeved by a shaft sleeve on the outer sides of the bearings; shaft clamping plates are arranged at the outer ends of the shaft sleeve; one end of each shaft clamping plate is fixed on the rope sheave shaft; the other ends of the shaft clamping plates are fixed on the rope sheave shaft fixing rack. According to the gear train device, the snap springs are arranged on the adjacent end surfaces of the two bearings, the shaft sleeve and the shaft clamping plates for fixation and positioning are mounted at the outer ends of the two bearings; when disassembly is required, the rope sheave shaft can be directly pulled out by only disassembling the shaft clamping plates, the shaft sleeve can drop off naturally, a rope sheave and bearing combined element can be directly replaced, so that the operation is simple, time-saving, labor-saving and very convenient.
Description
Technical field
The present invention relates to a kind of elevators field, be specifically related to a kind of convenient train wheel apparatus installing replacing.
Background technology
Elevator there is a lot of position use wheel train structure, and wheel train structure belongs to consumable accessory, it is frequently necessary to change, when wheel train structure needs to change, limited by elevator structure and space in a lot of situations, this train not easily entirety is pulled down, sometimes for dismounting train, it is necessary to the parts that other is in the way all are dismantled just passable. Need the train of a kind of convenient dismounting badly, improve work efficiency, reduce labor intensity.
The train of existing structure, its axle is Step Shaft, namely axially utilize the pillow block rank at axle center and jump ring to prevent bearing movement vertically, when needing to change, it is necessary to train (containing wheel, axle, bearing and other adnexa) is all pulled down just passable, and limited by elevator structure and space in a lot of situation, this train not easily entirety is pulled down, sometimes for dismounting train, it is necessary to the parts that other is in the way all are dismantled just passable, waste time and energy.
Summary of the invention
The technical problem to be solved is to provide a kind of convenient train wheel apparatus installing replacing, and it is easy to loading and unloading.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of convenient train wheel apparatus installing replacing, including rope sheave, sheave shaft and sheave shaft fixed mount, described sheave shaft is without multidiameter, two bearings being arranged side by side it are equipped with between rope sheave and sheave shaft, cavity between two bearings defines oil pocket, rope sheave is provided with the fuel filler neck connected with oil pocket, two bearings adjacent face is equipped with the jump ring being fixed on rope sheave, the cycle surface of jump ring and bearing is affixed, sheave shaft is cased with axle sleeve outside bearing, axle sleeve outer end is provided with axle clamp, axle clamp one end is fixed on sheave shaft, the axle clamp other end is fixed on sheave shaft fixed mount.
Described axle clamp is installed on sheave shaft, wherein offers polarizing slot on sheave shaft in axle sleeve outer end, and axle clamp one end is stuck in polarizing slot.
Jump ring is being arranged on two bearings adjacent face by the present invention, it is fixed location in two bearings outer end mounting sleeve and axle clamp, when disassembly is desired, only need to dismantling axle clamp, can directly extract sheave shaft out, axle sleeve can drop naturally, directly change rope sheave, Bearing assembly, simple to operate, time saving and energy saving, very convenient.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of the embodiment of the present invention;
Fig. 2 is the A-A profile of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Such as Fig. 1, shown in Fig. 2, a kind of convenient train wheel apparatus installing replacing, including rope sheave 1, sheave shaft 4 and sheave shaft fixed mount 8, sheave shaft 4 is without multidiameter, two bearings being arranged side by side 2 it are equipped with between rope sheave 1 and sheave shaft 4, cavity between two bearings 2 defines oil pocket, rope sheave is provided with the fuel filler neck 6 connected with oil pocket, two bearings adjacent face is equipped with the jump ring 5 being fixed on rope sheave, the cycle surface of jump ring 5 and bearing is affixed, draw-in groove is offered at rope sheave inner ring, jump ring 5 is stuck on draw-in groove, sheave shaft 4 is cased with axle sleeve 3 outside bearing 2, axle sleeve 3 and sheave shaft 4 matched in clearance, the inner ring end face of axle sleeve 3 inner face and bearing is affixed, axle sleeve 3 outer end is provided with axle clamp 7, axle clamp 7 one end is fixed on sheave shaft 4, axle clamp 7 other end is fixed on sheave shaft fixed mount 8.
Axle clamp 7 is installed on sheave shaft 4, wherein offers polarizing slot on sheave shaft 4 in axle sleeve outer end, and axle clamp 7 one end is stuck in polarizing slot.
Owing to the step on axle determines the stock diameter of processing axle, and stepped diameters is bigger than the shaft diameter being actually needed, it is also many that material is removed in the many and processing of meaning raw material, and the optical axis of the application only needs shaft diameter according to actual needs to process, raw material is saved, and removal material has lacked just to be saved process time. Additionally the countershaft stress of the step on axle has impact, and when there being step, stress concentration phenomenon easily occurs in step place, affects the use of axle, optical axis due to without step then without this problem, and the convenient scene of the application is changed and is installed.
