Abstract
The invention relates to a worm gear used for crossing shaft transmission shafts, in particular to a worm gear provided with a roll wheel. The worm gear changes a prior worm gear into a roll wheel. A sliding contact during the transmission is changed into a rolling contact to improve the transmission efficiency of a worm and the worm gear. The invention needs no expensive metals. A mounting seat is crossly mounted on a hub core of the worm gear by a bolt and is screwed tightly and connected firmly by a nut. The lower end of a mounting mandrel of the roll wheel with screw thread passes through the mounting seat and is screwed tightly and connected firmly by a nut. The upper end of a mounting shaft extending out of the mounting seat is provided with the roll wheel. The worm gear has the advantages of large transmission rate, light weight, simple structure, easy processing, long service life, low energy consumption in use and the invention is not limited by the transmission power when in use. The invention is broadly used for the transmission devices of worms and worm gears and can save massive copper materials.
Description
Technical field
The present invention relates to a kind of worm gear that is used for the intersecting axle transmission device, particularly, substitute worm gear commonly used with the gear of running roller.
Background technique
Worm screw, the worm screw in the worm gearing, the worm gear that uses all has profile of tooth at present, on-stream is to contact transferring power with sliding friction, thereby transmission efficiency is low, high, manufacturing difficulty that the worm gear processing technique requires, and need with valuable antifriction metal made worm gear and good lubricated and hot cool condition etc., thereby on demanding urgently the structure of worm gear and manufactured materials, seek to solve, to overcome the above-mentioned defective that exists.
Summary of the invention
The invention provides a kind of rim construction that changes worm gear, substitute the worm gear of band running roller of the tooth of worm gear with running roller.The flank of tooth of worm screw is contacted with the surface of the running roller of worm gear, change pure rolling contact of the present invention into by the simple sliding friction of prior art contact.
The present invention realizes with following mode.
A kind of worm gear with running roller, at wheel hub core excircle installation axle and running roller are installed, the fitting seat of running roller is installed on the core wheel through bolt, and screw affixed with nut, the threaded lower end of installation axle of running roller is passed fitting seat and is screwed affixed through nut, the pillow block that axle is installed is bearing on the corresponding step of fitting seat, and running roller is equipped with in the installation axle upper end of stretching out fitting seat, the axle upper end is installed lock screw or clamp ring are housed.Running roller is set with the running roller sleeve outward.Running roller is angular contact ball bearing or tapered roller bearing or needle bearing.Running roller is three angular contact ball bearings.
The worm gear of band running roller of the present invention maintains the performance of conventional Worm and Worm Gear Driving, and is big as velocity ratio, in light weight, compact structure.Because the tooth of worm gear substitutes with running roller, in the worm and worm wheel transmission, become the pure rolling friction contact by the simple sliding friction contact, its transmission efficiency obviously improves, the running roller of worm gear is simple in structure, thereby processing charges is lower, and is easy to manufacture, long service life and for ease of maintenaince.Particularly be not subjected to the restriction that transmission power can not be too big and do not need expensive antifriction metal-tin bronze.Its suitable worm gear of making the worm and worm wheel transmission device uses.

Embodiment
The worm gear of band running roller of the present invention, its structure that mainly is different from existing toothed worm gear are the teeth that replaces worm gear with running roller, and the running roller number of worm gear is identical with the worm gear number of teeth commonly used, thereby the rim construction of worm gear of the present invention is different with worm gear arrangement commonly used.And bring the wheel hub cored structure that corresponding variation is arranged.
Embodiment one, sees accompanying drawing 1.
The end that axle 3 is installed has screw thread; Its other end is equipped with running roller 1, running roller 1 is made of rolling bearing and installation axle 3, the present embodiment rolling bearing adopts three angular contact ball bearings, axle 3 is installed passes fitting seat 4, the pillow block that axle 3 is installed is bearing on the corresponding step in the fitting seat 4, stretch out outside the fitting seat 4 threaded installation axle 3 lower ends, and be installed with pad 8 and screw affixed fitting seat 4 through nut 9.The upper end of axle 3 band running rollers 1 is installed stretches out outside the fitting seat 4, thrust washer 2 is contained in running roller 1 and the corresponding pillow block place that bearing 3 is installed, and is used for support rolling bearing.Axle 3 upper ends are installed to be had baffle plate 2 and has lock screw 13 to be tightened on and install on the axle 3, the slippage that makes progress of the bearing of the running roller 1 that is used for blockading.Fitting seat 4 is put in the groove of wheel hub core 5, and the corresponding aperture that passes wheel hub core 5 and fitting seat 4 with bolt 6 screws affixed through nut 7.
Embodiment two, see accompanying drawing 2
The end that axle 3 is installed has screw thread, and its other end is equipped with running roller 1, is set with running roller sleeve 10 in the outside of running roller 1.Running roller 1 is made of rolling bearing.The present embodiment rolling bearing adopts two tapered roller bearings.Running roller 1 is installed on the corresponding axle collar platform that axle 3 is installed, axle 3 is installed passes fitting seat 4, the pillow block that axle 3 is installed is bearing on the corresponding step of fitting seat 4, and stretch out outside the fitting seat 4 threaded installation axle 3 lower ends, and is installed with pad 8 and screws affixed fitting seat 4 through nut 9.The upper end of axle 3 is installed stretches out outside the fitting seat 4, clamp ring 11 is contained in the upper end that axle 3 is installed, and running roller 1 outside slippage is used for blockading.Fitting seat 4 is put in the groove of wheel hub core 5, and the corresponding aperture and the pad 8 that pass wheel hub core 5 and fitting seat 4 with bolt 6 screw affixed through nut 7.
Fig. 3 is this worm gear user mode schematic representation.When this worm gear is used for the worm and gear transmission, the rolling Contact Transmission schematic representation of tooth of worm screw 14 and the running roller of this worm gear 1.Running roller 1 distribution is installed in the outer periphery of the wheel hub core 5 of worm gear, replaces the tooth of prior art worm gears with a plurality of running rollers 1.
It is big, in light weight that the present invention has a gearratio, and compact conformation is easy to processing, long service life and for ease of maintenaince wait characteristics, When this worm gear is used for the worm and worm wheel transmission device, energy consumption was low when its used, and the transmission efficiency height is applicable to be widely used in worm screw In worm gearing, and can save a large amount of copper materials.
