Abstract
The invention discloses a high-speed and high-efficiency fixed-shaft pulley. The high-speed and high-efficiency fixed-shaft pulley consists of a central main shaft assembly, a mechanical case body and a baffle cover, wherein the central main shaft assembly comprises a main shaft and a bearing; the front end of the main shaft is provided with external screw threads; the bearing is embedded in the rear part of the main shaft; a stepped hole is formed in the mechanical case body; the inner diameter of a big hole of the stepped hole is matched with the outer diameter of the bearing; the inner diameter of a small hole of the stepped hole is matched with the outer diameter of the main shaft; a pit is formed on the inner side of the baffle cover; and the baffle cover is connected to the rear end of the mechanical case body. In the high-speed and high-efficiency fixed-shaft pulley, the traditional friction sliding is converted into mechanical energy. The mechanical property of the pulley is achieved by means of the mechanical energy of the bearing. The pulley has the advantages that: the effect is good; the use is safe; the speed can be increased; the service life can be prolonged; the friction is reduced; the bearing capacity is increased; and the lubricating property is enhanced.
Description
Technical field
The invention belongs to mechanical slip pulley technical field, relate in particular to that push-and-pull gate runway hangs with boat, portal frame boat is hung the pulley that uses on the runway.
Background technique
Machinery slip pulley can both be used widely in each enterprise, on the building site, on the equipment or the like, brings convenience for the application of society, is to embody the model who innovates.Common its friction factor of friction pulley of single function originally is big, ability to bear is little, noise is big, greasy property is bad, speed is slow, the life-span is short or the like, uses wideless.
Summary of the invention
It can dead axle be pulley that technical problem to be solved by this invention provides the high-speed and high-efficiency that a kind ofly improves speed, runs extended services, increases ability to bear.
Adopt following technological scheme in order to solve the problems of the technologies described above: a kind of high-speed and high-efficiency can dead axle be a pulley, is made up of central principal axis assembly, mechanical casing, door, and the central principal axis assembly comprises that front end is provided with externally threaded main shaft and the bearing that is nested in the main shaft rear portion; Machinery is provided with shoulder hole in the casing, and the macropore internal diameter of shoulder hole matches with bearing outside diameter, hole diameter and main shaft external diameter match; The door inboard is provided with pit, and door is connected mechanical box back.
Central principal axis, mechanical casing and door are all processed by carbon steel material.
Described central principal axis rear portion is connected with bearing through bearing baffle.
The friction slip that the present invention breaks traditions is converted into mechanical energy, relies on bearing mechanical energy to slide, and brings into play its mechanical property.Respond well, safe in utilization, ability raising speed runs extended services, and reduces friction, and increases ability to bear, strengthens greasy property.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of high-speed and high-efficiency can dead axle be a pulley, is made up of central principal axis assembly, mechanical casing, door, and central principal axis, mechanical casing and door are all processed by carbon steel material.The central principal axis assembly comprises that front end is provided with externally threaded main shaft 3, is nested in the bearing 5 at main shaft 3 rear portions through bearing baffle 4; In the silk hole of a diameter 8mm of rear-end of spindle center processing, thus be used to prevent service time of a specified duration or speed is fast, the influence of bearing play was slided when ability to bear was big.Be provided with shoulder hole 2 in the machinery casing 1; The macropore internal diameter of shoulder hole matches with bearing outside diameter, hole diameter and main shaft external diameter match, and adopts mechanical casing to reduce noise, has improved ability to bear; Improve speed, can prevent other foreign material get into influences pulley in the bearing sliding effect again.Door 7 can prevent that through being bolted to mechanical box back other foreign material from getting in the bearing, influences the sliding effect of pulley; The door inboard is provided with pit 6, and pit and bearing are supporting, and inside lubricating oil filling so that the pulley using effect is good, reduces slip resistance, increases the life-span of pulley.
