Abstract
The utility model discloses a reduction gear unit axle assembly's improvement structure for chain lever block. It includes speed reduction piece gear portion, reduction gear unit minor axis and drive gear portion, speed reduction piece gear portion, reduction gear unit minor axis and drive gear portion constitute for one whole together. The utility model discloses prior art speed reduction piece gear and drive gear has been abandoned and the shaft hole need be seted up respectively to and the reduction gear unit axle must set up corresponding axle rank, the substitute is on the reduction gear unit minor axis straight forming for speed reduction piece gear portion and drive gear portion, makes this three close as together that whole the pressure equipment self is exempted from moreover to the bulk strength height in order to constitute single part, and this not only saves and assembles man -hour, and the utility model discloses a single part is higher than the part accuracy that prior art needed three component assembly to become, furtherly the utility model discloses a transmission precision is high, owing to after self exempting from the pressure equipment, then can avoid prior art piece gear easily to produce the problem of deformation when the pressure equipment.
Description
[technical field]
This utility model relates to the improvement knot of a kind of hand chain lever hoist deceleration transmission axle assembly
Structure, the improvement with hand chain lever hoist driving member is relevant.
[background technology]
Existing hand chain lever hoist drive mechanism is typically with double reduction transmission, and biography of slowing down
Axis of a movable block assembly is positioned at the first order decelerating phase, by two set deceleration transmission axle assemblies by a pair
Deceleration blade gear engages with the end tooth transmission of major axis jointly, this deceleration transmission axle assembly be by
Deceleration transmission axle, the deceleration blade gear being loaded on this deceleration transmission axle and travelling gear composition, deposit
Deficiency when press-fiting low precision, assembly fee, and add deceleration blade gear in man-hour and must offer axis hole,
And deceleration transmission axle must offer the axle rank matched with this axis hole, due to deceleration blade gear thickness
Relatively thin, its intensity can be affected after offering axis hole, and easily make when press-fiting deceleration blade gear produce
Deformation.
[utility model content]
The technical problems to be solved in the utility model be the deficiency existed for above-mentioned prior art and
The improved structure of a kind of hand chain lever hoist deceleration transmission axle assembly that need not assemble is provided,
To improve overall construction intensity and assembly precision.
To this end, the technical scheme that the above-mentioned technical problem of this utility model solution is used is as follows:
The hand chain lever hoist improved structure of deceleration transmission axle assembly, including deceleration blade gear
Portion, the short axle of deceleration transmission and transmission gear, described deceleration blade gear part, the short axle of deceleration transmission
A single piece is consisted of together with transmission gear.
This utility model has the advantage that as follows:
Abandon prior art deceleration blade gear and travelling gear has been respectively required for offering axis hole, and subtracted
Speed power transmission shaft must offer corresponding axle rank, the substitute is: on the short axle of deceleration transmission directly
Be shaped to deceleration blade gear part and transmission gear, make deceleration blade gear part, transmission gear and
Deceleration transmission short axle three is combined into overall to constitute single part together, and bulk strength is high, and
Self exempting to press-fit, this not only saves assembly work, and this utility model single part ratio is existing
The element precision that technology needs three parts to be assembled into is high, says further, biography of the present utility model
Dynamic precision is high, after self exempting to press-fit, then prior art deceleration blade gear can be avoided to press-fit
Time be easily generated the problem of deformation, compared with prior art, further increase of the present utility model
Transmission accuracy is high.
When being assembled in hand chain lever hoist as a single piece, follow-up maintenance can realize convenient from
Integral disassembly, assembly on hand chain lever hoist, thus reduce assembling skill set requirements.
[accompanying drawing explanation]
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is right diagram of the present utility model；
Fig. 3 is to be assembled with hand chain lever hoist explosive view of the present utility model.
[detailed description of the invention]
Refer to Fig. 1, shown in 2, be preferred embodiment of the present utility model.
The hand chain lever hoist improved structure of deceleration transmission axle assembly, including deceleration blade gear
Portion 1, the short axle of deceleration transmission 2 and transmission gear 3, deceleration blade gear part 1, deceleration transmission are short
Axle 2 consists of a single piece together with transmission gear 3.
This utility model integrally-built deceleration transmission axle assembly is warm forging.
Warm forging forming temperature is 120 degree.
The small-sized hands that this utility model applies also for used by electric wire, cable stringing is pulled in tightener.
When this utility model is specifically installed: two set deceleration transmission axle assemblies are installed to left casing 6
With on left wallboard 7, make two set deceleration transmission axle assemblies be distributed in the both sides of major axis 4, often overlap
The plate gear portion 1 of deceleration transmission axle assembly all engages with the end tooth 41 of major axis 4, and often set subtracts
The transmission gear 3 of speed power axle assembly all with the final-stage gear 51 of chain wheel assembly 5 side end
Engagement, chain wheel assembly 5 is sleeved on major axis 1.
The short axle of deceleration transmission 2 is designed to short axle construction, and double reduction drive mechanism is compact, transmission
Route is short.
