Abstract
The utility model provides a tool for quickly dismounting an engine belt pulley. The tool comprises a thread bushing, inner threads arranged on the upper portion of the thread bushing are internally connected with a lead screw with a cone face arranged at the lower end, and an outer/inner thread barrel matched with the inner/outer threads of the end of a belt pulley taper sleeve is arranged on the lower portion of the thread bushing. The thread bushing of the tool is screwed down on the taper sleeve with the inner (outer) threads of the belt pulley, the cone face of the lower end of the lead screw abuts in a locating hole in the end of a crankshaft, the lead screw is rotated through a handle, the thread bushing pulls the taper sleeve out slowly under the action of axial tension generated by the lead screw, and therefore the belt pulley is easily taken down. The tool is low in manufacturing cost, small in structure, simple in operation, easy to use and capable of being widely applied to the maintenance operation of diesel engines of multiple types, meanwhile, the belt pulley and a shock absorption rubber sleeve are guaranteed not to be damaged, the cost of fittings is saved, and maintenance efficiency is improved.
Description
Technical field
The utility model belongs to instrument, specifically, relates to a kind of instrument of quick-detachment engine belt pulley.
Background technology
In the loading and unloading Transport Machinery of port and pier, most of plant equipment are 6102,6105,6110, the 6113 model Diesel engines that adopt, and above-mentioned engine belt pulley is mounted in crankshaft front end, and coning sleeve is installed on the bent axle, with the belt pulley tensioner.The damping gum cover also is housed in belt pulley.When engine is carried out flight-line maintenance, sometimes need dismantling belt pulleys is got off, after finishing, maintenance installs again.
The dismounting mode of existing belt pulley is to adopt to take off son with the belt pulley of pawl, its pawl is stuck on the outer of belt pulley, and belt pulley is pulled out together with band (interior) externally threaded coning sleeve.Owing to cooperating tension between belt pulley and the coning sleeve, when the son dismounting is taken off in use, frequent appearance is taken off belt pulley broken, perhaps very easily causes the damage of belt pulley damping gum cover, causes former railway carriage belt wheel can't continue to use, reduced the utilization rate of parts, cause simultaneously unnecessary accessory waste, when causing spare and accessory parts directly to damage, the loss that indirectly causes is also larger, to postpone maintenance cycle, improve maintenance cost.
6102, the belt pulley of 6105,6110,6113 serial model No. Diesel engines is mounted in crankshaft front end, utilizes the male cone (strobilus masculinus) of the coning sleeve of (outward) screw thread in the band with the belt pulley tensioner, strengthens the degree of reliability of belt pulley locking.
The dismantling belt pulleys with the Diesel engine of various models that how can be fast and safely gets off, and needs a kind of general adaptive extracting tool that possesses badly.
Summary of the invention
The utility model provides a kind of instrument of quick-detachment engine belt pulley, and it can solve fragile belt pulley and other parts that prior art exists, and the problem that maintenance cycle is long, maintenance cost is high.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of instrument of quick-detachment engine belt pulley comprises thread bush, connects the leading screw of the lower end headband conical surface in the internal thread that thread bush top is provided with, and the bottom of thread bush is provided with the outer/inner thread barrel of adaptive belt pulley coning sleeve termination inside/outside screw thread.
Namely when belt pulley coning sleeve termination was internal thread, the bottom of thread bush was provided with adaptive external screw thread cylinder;
When belt pulley coning sleeve termination was external screw thread, the bottom of thread bush was provided with adaptive internal thread cylinder.
In order to make things convenient for the rotation of leading screw, the top of described leading screw is provided with the flexible handle that is horizontally through leading screw.
Instrument using method of the present utility model is: the thread bush of instrument is twisted in the belt pulley band (outside) on the coning sleeve of screw thread, leading screw passes the internal thread on thread bush top, the conical surface of leading screw lower end is withstood in the locating hole of bent axle termination, axial tension by the rotating threaded shaft generation, thread bush is slowly pulled out coning sleeve, the belt pulley endoporus is in vacant state, thereby easily takes off belt pulley.
6102,6105 serial model No. Diesel engine belt pulleys are to adopt the externally threaded coning sleeve of termination band, when adopting instrument dismounting of the present utility model, adopt the thread bush bottom with the instrument of internal thread cylinder;
6110,6113 serial model No. Diesel engine belt pulleys are to adopt the tapped coning sleeve in termination, when adopting instrument dismounting of the present utility model, adopt the thread bush bottom with the instrument of external screw thread cylinder.
The utility model compared with prior art has the following advantages and good effect:
Tool making of the present utility model is with low cost, structure is little, simple to operate being easy to used, and can be widely used in the maintenance activity of Multiple Type Diesel engine, guarantees that simultaneously belt pulley and damping gum cover are not damaged, and saves fittings cost, improves maintenance efficiency.
