Description
Technical Field
The utility model relates to the field of elevator equipment, in particular to a pulley assembly.
Background
Along with the development of trade, the steel band ladder accounts for than the volume more and more greatly in low-speed ladder and villa ladder china, and in the steel band ladder now, the rope sheave subassembly by a round steel processing recess, then impress the bearing, adorn the jump ring, according to the requirement of groove number, through the axle installation to the well in, this kind of rope sheave subassembly processing cost is high, the recess is more difficult more processing more to also be difficult in the field installation.
SUMMERY OF THE UTILITY MODEL
Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides the pulley assembly, which effectively solves the problems of high processing difficulty, short service life and inconvenience in installation of the conventional pulley assembly.
The technical scheme for solving the problems comprises an annular sleeve, wherein an annular groove is formed in the outer edge of the annular sleeve, an annular protrusion is arranged on the right side in the annular sleeve, a bearing is arranged in the annular sleeve, the bearing is arranged in the annular sleeve in an interference fit mode and limited by the annular protrusion, and an elastic check ring for holes is arranged on the left side of the bearing.
Preferably, the inner edge of the annular sleeve is provided with an annular mounting groove, and the hole is mounted in the mounting groove by an elastic retainer ring.
Preferably, a positioning retainer ring sleeved on the shaft is arranged between the two adjacent assemblies.
Preferably, the two assemblies at the two ends of the shaft are installed in opposite directions.
Preferably, circlips for shafts are sleeved at two ends of the shaft.
The pulley assembly is novel in concept, ingenious in structure and high in practicability, and effectively solves the problems that the existing pulley assembly is high in processing difficulty, short in service life and inconvenient to install.
Drawings
FIG. 1 is a front sectional view of the installation of a single assembly of the present invention.
Fig. 2 is a left side view of the inventive assembly.
FIG. 3 is a front cross-sectional view of a plurality of components of the present invention as mounted on a shaft.
Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As can be seen from fig. 1 to 3, the present invention includes an annular sleeve 1, an annular groove 2 is provided on the outer edge of the annular sleeve 1, an annular protrusion 3 is provided on the right side inside the annular sleeve 1, a bearing 4 is provided inside the annular sleeve 1, the bearing 4 is installed inside the annular sleeve 1 in an interference fit manner and is limited by the annular protrusion 3, and an elastic collar 5 for holes is provided on the left side of the bearing 4.
In order to realize the installation of the circlip 5 for holes, the inner edge of the annular sleeve 1 is provided with an annular installation groove, and the circlip 5 for holes is installed in the installation groove.
In order to realize the limit of a plurality of assemblies when the assemblies are installed on the shaft, a positioning retainer ring 6 sleeved on the shaft is arranged between the two adjacent assemblies.
In order to achieve the mounting on the shaft, the two components at the two ends of the shaft are mounted in opposite directions.
In order to realize the sealing between the shaft and the end part assembly, two ends of the shaft are sleeved with elastic check rings 7 for the shaft.
The specific working process of the utility model is as follows: the device is sleeved on a rotating shaft and is installed in a well, a steel wire rope can be used after bypassing an annular groove, the components are rope wheel component units, the number of the components is selected according to corresponding requirements, the components are connected in series by a shaft, the method is simple, the components are separated from one another by positioning check rings 6, and all the units do not need to rotate synchronously.
The significant benefits of the present device:
1. the way the present arrangement increases the service life of the bearings 4 is to form separate grooves each with a separate bearing 4 supporting them on the mounting shaft, which increases the number of bearings 4 and results in a reduced load per bearing 4.
2. The processing difficulty is reduced, and the processing precision, namely the concentricity of the annular groove and the hole of the bearing 4, is ensured.
3. Retrench the modularization, and bearing 4, circlip all are standard parts, and processing cost is low, and administrative cost, assembly cost are all effectively reduced.
